Image_Moo is currently at version 1.1.6 – 5th Feb 2014
The CI library for image manipulation is great, but I found it awkward to use when doing multiple processes. So I wrote my own library which I’m happy for you to play with and send feedback. It is limited to PHP 5 and GD2 only, sorry, but that suits my needs
Download image_moo (v1.1.5 GIT)
Install
Copy the unzipped file to /system/application/libraries for CI > 1.7.2 and /application/libraries for CI 2.
Functions
load($x) - Loads a base image as specified by $x - JPG, PNG, GIF supported. This is then used for all processing and is kept in memory till complete load_temp() - Copies the temp image (e.g. cropped) and make it the new main image save($x,$overwrite=FALSE) - Saved the manipulated image (if applicable) to file $x - JPG, PNG, GIF supported. If overwrite is not set file write may fail. The file saved will be dependant on processing done to the image, or a simple copy if nothing has been done. get_data_stream($filename="") - Return raw data that can be encoded and displayed in an image tag, e.g. $x = $this->image_moo->load('x')->get_data_stream(); $y = base64_encode($x); print '<img src="data:image/jpg;base64,'.$y.'">'; save_dynamic($filename="") - Saves as a stream output, use filename to return png/jpg/gif etc., default is jpeg (This also sends relevant headers) save_pa($prepend="", $append="", $overwrite=FALSE) - Saves the file using the original location and filename, however it adds $prepend to the start of the filename and adds $append to the end of the filename. e.g. if your original file was /this/that/file.jpg you can use save_pe("pre_", "_app", TRUE) to save it as /this/that/pre_file_app.jpg resize($x,$y,$pad=FALSE) - Proportioanlly resize original image using the bounds $x and $y, if padding is set return image is as defined centralised using current background colour (set_background_colour) resize_crop($x,$y) - Proportioanlly resize original image using the bounds $x and $y but cropped to fill dimensions stretch($x,$y) - Take the original image and stretch it to fill new dimensions $x $y, unless you have done the calculations this will distort the image crop($x1,$y1,$x2,$y2) - Crop the original image using Top left, $x1,$y1 to bottom right $x2,y2. New image size =$x2-x1 x $y2-y1 rotate($angle) - Rotates the work image by X degrees, normally 90,180,270 can be any angle.Excess filled with background colour load_watermark($filename, $transparent_x=0, $transparent_y=0) - Loads the specified file as the watermark file, if using PNG32/24 use x,y to specify direct positions of colour to use as index make_watermark_text($text, $fontfile, $size=16, $colour="#ffffff", $angle=0) - Creates a watermark image using your text and specified ttf font file. watermark($position, $offset=8, $abs=FALSE) - Use the loaded watermark, or created text to place a watermark. $position works like NUM PAD key layout, e.g. 7=Top left, 3=Bottom right $offset is the padding/indentation, if $abs is true then use $positiona and $offset as direct values to watermark placement shadow($size=4, $direction=3, $colour="#444") - Add a basic shadow to the image. Size in pixels, note that the image will increase by this size, so resize(400,400)->shadow(4) will give an image 404 pixels in size, Direction works on the keypad basis like the watermark, so 3 is bottom right, 7 top left, $color if the colour of the shadow. border($width,$colour="#000") - Draw a border around the output image X pixels wide in colour specified. This can be used multiple times, e.g. $this->image_moo->border(6,"#fff")->border(1,"#000") creates a photo type of border border_3d($width,$rot=0,$opacity=30) - Creates a 3d border (opaque) around the current image $width wise in 0-3 rot positions, $opacity allows you to change how much it effects the picture filter($function, $arg1=NULL, $arg2=NULL, $arg3=NULL, $arg4=NULL) - Runs the standard imagefilter GD2 command, see http://www.php.net/manual/en/function.imagefilter.php for details round($radius,$invert=FALSE,$corners(array[top left, top right, bottom right, bottom left of true or False)="") default is all on and normal rounding. This functions masks the corners to created a rounded edge effect. Image helper functions display_errors($open = '<p>', $close = '</p>') - Display errors as Ci standard style. Example if ($this->image_moo->error) print $this->image_moo->display_errors(); ignore_jpeg_warnings($onoff = TRUE) - relax the GD strictness for loading jpegs allow_scale_up($onoff = FALSE) - Allow you to stretch images that are too small to match resize/crop request real_filesize() - returns the size of the file in B,KB,MB.GB or T (as if!) set_jpeg_quality($x) - quality to wrte jpeg files in for save, default 75 (1-100) set_watermark_transparency($x) - the opacity of the watermark 1-100, 1-just about see, 100=solid check_gd() - Run to see if you server can use this library clear_temp() - Call to clear the temp changes using the master image again clear() - Use to clear all loaded images form memory
Examples
All the examples here will use the image as shown on the right hand side (click to expand) and we will use the save_dynamic output instead of saving as a file. Of course all the examples are missing 2 bits of common code, to reduce space used. Before image_moo works, you need to load it with $this->load->library(“image_moo”);, and after running a function you should check for errors and report as needed. if($this->image_moo->error) print $this->image_moo->display_errors();.
Cropping
The following section shows the various ways Image_moo can crop and resize an image
Simple crop Image is cropped to a max in either axis of 100 pixels, output image will be the same ratio as the input image $this->image_moo ->load("DSC01707.JPG") ->resize(100,100) ->save_dynamic()Crop keep proportions but outputting a fixed size Image is cropped as above, but the output is padded to fit the specified size. Please note I set a funny background colour for visual reasons only $this->image_moo ->load('DSC01707.JPG') ->set_background_colour("#49F") ->resize(100,100,TRUE) ->save_dynamic();
Resize with crop Image is resized to an exact size based on cropping a ratio match from the original image $this->image_moo ->load('DSC01707.JPG') ->resize_crop(100,100) ->save_dynamic();
Borders
In these examples we will add various borders to the output image
Simple photo style border $this->image_moo ->load('DSC01707.JPG') ->resize_crop(100,100) ->border(5, "#ffffff") ->border(1, "#000000") ->save_dynamic();Rounded corners Note that the background colour used can be set with the set_background_colour command, we have left it white for this example. $this->image_moo ->load('DSC01707.JPG') ->resize_crop(100,100) ->round(5) ->save_dynamic();
3d effect $this->image_moo ->load('DSC01707.JPG') ->resize_crop(100,100) ->border_3d(5) ->save_dynamic();
Watermarking
You can also apply watermarks to your images!
Using an image $this->image_moo ->load('DSC01707.JPG') ->load_watermark("matmoo.gif") ->resize(400,400) ->watermark(5) ->save_dynamic();Using your own text $this->image_moo ->load('DSC01707.JPG') ->make_watermark_text("MatMoo.com", "DANUBE__.TTF", 25, "#000") ->resize(400,400) ->watermark(2) ->save_dynamic();
Conclusion
As you can see this library is much easier to use than that default Image_lib that comes with CI, especially when it comes to mulitple picture outputs. For example; once an image is loaded you can run multiple commands and saves on it $this->image_moo->load(“image.jpg”)->resize(600,600)->save(“large.jpg”)->resize(400,400)->save(“medium.jpg”)->resize(100,100)->save(“small.jpg”) and of course you can add watermarks after each resize (or borders) as well.

How to rename the original image’s name?
$this->image_moo->load(‘a’)->save(‘b’);
hello there?
when i resize .gif image it losses its quality and image format…
will anybody help me to solve this issue…?
Would need examples to see why, and what format are you saving out as?
i solved the problem of transparency by making some change in the line of image_moo.php
here are the changes….
===============================
/near of line 553… add this line
//if padding, fill background…
if ($pad)
{
$col = $this->_html2rgb($this->background_colour);
if($this->background_colour != “”){
$bg = imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]);
imagefilledrectangle($this->temp_image, 0, 0, $tx, $ty, $bg);
}else{
imagecolortransparent ( $this->temp_image , imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]) );
}
}
===============================
//and finally use…
$this->image_moo
->load(‘source_image.png’)
->set_background_colour(“#TRANSPARENT”)
->resize(100,100,TRUE)
->save(“saved_image.png”); //remember save to png
Hello dude,
when i upload .png image to resize…it’s transparent background turns to white…
will u plz help me to solve this issue
i am using like this
here is my code…
==============================================
public function index()
{
$this->load->library(‘image_moo’);
$TempImageName = $_FILES[‘uploaded_image’][‘tmp_name’];//temp image name
$OldImageName = $_FILES[‘uploaded_image’][‘name’]; // real image name
$main_image_saved_dir = “assets/uploaded/img/”;
$this->image_moo->load($TempImageName)->resize(1024,768)->save($main_image_saved_dir.$OldImageName); $this->image_moo->load($TempImageName)->resize(600,600)->save($main_image_saved_dir.”600×600″.$OldImageName)->resize(400,400)->save($main_image_saved_dir.”400×400″.$OldImageName)->resize(100,100)->save($main_image_saved_dir.”100×100″.$OldImageName);
}
==============================================

Hi Mat,
I need to resize just the height.
How can i do it.
Set the height you want, but set the width to 99999 that way it will always be restricted to the height.
Dude, your lib rocks!
But is there a way to blur images?
Untested, you should be able to do $this->image_moo->filter(IMG_FILTER_GAUSSIAN_BLUR)…;
I love your work, i’m testing and compare default image library with your extends image library… good service dude.
Hello,
It’s a good library.
But can i use it to convert png and gif to jpg ?
Yes just save and specify the file name
Looking at the code/error message you are trying to crop it to a larger dimension than the original image.
Hi,
Am thanks for the such a good library
Am using your library to crop and resize the images, it is working fine in the way,
But while crop some of the larger images am getting following error
Array ( [error] =>
Invalid crop dimensions, either – passed or width/heigh too large 0/0 x 1106/240
)
What i have to do ?? can i set the default height and width for the crop, if i set default Height and Width, the crop will work ??
Hi.
Why doesn’t work my code ?
$this->load->library(‘admin/image_moo’);
$this->image_moo->load(FCPATH.’Dosyalar/orjinal/’.$fileName)->resize(200,100000)->save(FCPATH.’Dosyalar/kucuk/’.$fileName)->resize(350,100000)->save(FCPATH.’Dosyalar/orta/’.$fileName)->resize(800,100000)->save(FCPATH.’Dosyalar/buyuk/’.$fileName);
These codes redirect me to a blank (white) page. I’m sure files were uploaded and path is correct.
If u have any sugegestion i ll be grateful,
Thanks a lot.
I would turn on error logging in CI to try and see what is going on… how big is the source image? could be running our of memory etc.
Hi,
I solved the problem. I saw that image_moo requires GD library. I am a poor PHP coder. 🙂
Thanks so much.
I had the same problem ! ubuntu 14 with apache 2.4 php 5.5
Solved it by running this in my terminal
apt-get install php5-gd
then I restarted apache, now it works flawless!
Hi there
i fix the rotate functions and now is working with alpha png
public function rotate($angle)
//———————————————————————————————————-
// rotate an image bu 0 / 90 / 180 / 270 degrees
//———————————————————————————————————-
{
// validate we loaded a main image
if (!$this->_check_image()) return $this;
// if no operations, copy it for temp save
$this->_copy_to_temp_if_needed();
// set the colour
$col = $this->_html2rgb($this->background_colour);
//$bg = imagecolorallocate($this->temp_image, $col[0], $col[1], $col[2]);
$bg = imagecolorallocatealpha($this->temp_image, 0, 0, 0, 127);
// rotate as needed
$this->temp_image = imagerotate($this->temp_image, $angle, $bg);
imagealphablending($this->temp_image, false);
imagesavealpha($this->temp_image, true);
// set sizes
$this->_set_new_size();
// return self
return $this;
}
Thanks I’ll add that in and get the code on Git
Hi, Excelent work,
Im new in CodeIgniter, (like 3 weeks),
I have a very stupid question: How to display the image in the view file?
The next code give me an image error:
‘The image “http://localhost/ci_projects/ci_metronic_1/test” cannot be displayed because it contains errors.’
Untitled Document
image_moo
->load('assets/uploads/soldiers.jpg')
->resize(100,100)
->save_dynamic()
?>
but if i remove all HTML tags, the image is displayed.
How to display the image in the view file?
Thanks for this good library.
Got it,
just i write the code in a function display() of my controller Image(); then in my view, the img src=”image/display” and thats it.
All the configuration of the image to display is in the controller, not in the view.
EXCELENT LIBRARY !!!
Felicitaciones, justo lo que estaba buscando. En 2 pasos, pude terminar mi trabajo. Muchas gracias por este gran aporte.
does not work at all.
I cant see errors, writing
if($this->image_moo->error) print $this->image_moo->display_errors();

Image paths can not load form a http location, you need the real file path where the image is stored.
There was a bug on image rotating.
on line 670 $$this->background_colour should be $this->background_colour
Did a pull request on github with the fix https://github.com/darkness/codeigniter-image-moo/pull/2
Other than that, nice script 🙂 very handy to use!
The git repo is not mine, need to put one on my account 🙂
ah ok, I just assumed it was 🙂
what u mean by real path ?
i am using the http path and the result is “no main image loaded!” !! ?
what the solution?
http://php.net/manual/en/function.realpath.php
You need to load using a full local file reference, not a http path
Moo! (as in Hi!)
A little problem with watermarking. If the watermark image or watermark text image is too big, it does not show the watermark at all. This gives a little problem because our customers should be able to set the font-size + text or image and the watermark is added to all pictures that they upload, even smaller ones.
I guess I could circumvent this by first creating the watermark image on the fly depending on dimensions of the uploaded image first and then add the watermark to that.
PS. Aww crap! I just read the source and you have that “// check watermark will fit!” comment there 😛
For the time being, I just commented it out and watermark works now (It doesnt matter if it doesnt fit completely in every pic).
Thanks for great lib!
Ah, classic TODO 🙂 glad you find it useful
Hi,
I recently switched to Laravel from CI, and could not find any good image processors, so I decided to port yours! 😀
http://forums.laravel.io/viewtopic.php?id=6159
I already gave you full credit, I just wanted to drop this, I hope everything’s okay.
Thanks again for the awesome library.
Cheers,
Thanks for letting me know 🙂 I’ll get the latest version out soon
Hi
i thak you all for giving valuable notes .you all helped me to get this and work great. Please continue your service .
Thank you
Thanks, It work well
Thanks for your work.
It helps me to fix the issue when I unzip, save, then make thumb and resize for multiple files.
When use CI Image lib, it doesn’t work. but use yours it work
I really appreciate that.
Great script, excelent work, and also it is very easy to use. You just saved my day 😀 Keep up the good work
I just started using this after finding it in the GroceryCRUD package. It is a nice addon to codeIgniter bacause it has some functions the CI image manipulation library is missing.
Hi, i want to ask some question
i have image 200 x 120
and i want to resize to 460 x 290
Why the image output still same 200×120?
not 460×270.
image type jpeg.
Thanks.
What code are you using?
Hello
Thank u for your hard work.
I have been trying for 12 hours nonstop to make it work when I upload 2 or more pictures that require different resizing. Imagine that I may want to upload a thumb and then the other pics at a larger size.
In your explanations you write about doing different things to a single picture, but I am using the grocerycrud library and I have one upload button for thumb and another one for pic, which should be resized at different sizes. Cant find the right way to use the after_upload callback functions.
Never used the grocerycrud library, sorry 🙁
Just a quick note. I noticed that set_watermark_transparency($x) is backwards where 1 gives you a solid and 100 is invisible.
Depends if the glass if half full or half empty 🙂
Using it with image area select for cropping and it rocks!
Great job,
Thanks 🙂
Hey, just wanted to say thanks, this library rocks 🙂
Hello Mat,
First of all I want to thank you for your great plugin 🙂
I have been using it on a project before and it works just fine.
I am currently trying to resize transparent PNGs but I get a black background and the transparency is lost….
Any clue on what to change to allow transparent PNGs resizing ?
I found a fix for my issue !
Just added two lines at line 545 after:
$this->temp_image = imagecreatetruecolor($tx,$ty);
Here is the code:
imagealphablending( $this->temp_image, false);
imagesavealpha( $this->temp_image, true);
Thanks for that – I need to spend some time improving png transparency all around 🙂
Justo lo que andaba buscando para mis aplicaciones, funciona a la perfección. Thanks!
It’s working now. I changed the code on codeigniters forum solution.
I just changed $this->width and $this->height for $tx and $ty
This is how the code should look on lines 555 to 560
Yep, I need to make an update, sorry 🙁
Hey, just wanted to say thanks for this library. I’ve used it in the past for a big B2B e-commerce project and now I’m using it for one of my smaller personal projects.
All the best,

Your welcome! Donations welcome 🙂
Hello,
i am tried to load a simple image
class image extends CI_Controller {
function index(){
$this->load->library(“image_moo”);
$this->image_moo
->load(“/../imagini/r.jpg”)
->resize(100,100);
if($this->image_moo->errors)
print $this->image_moo->display_errors();
}
}
but i have a error “Could not locate file”.
I am created a folder “imagini” where is the main folders(application and system). I gave the path “/../imagini/r.jpg” and nothing . Can give me a solution .
Thank you ,
The path will depend on your config, I can’t tell you what it will be. You could user $_SERVER[“document_root”] to get teh correct root folder of the website and append the path to that.
Hello again ,
i have the same error:
i am tried this
….
$path= base_url().’imagini/r.jpg’;
$this->load->library(“image_moo”);
$this->image_moo->load($path)
…..
/// Could not locate file http://localhost:8080/cc/imagini/r.jpg
The path is correct but i do not understand why does not work.
Thank you ,
I’m not sure what to say, that error is set with http://php.net/manual/en/function.file-exists.php so maybe it’s a safe mode restriction?
the folder where i have saved image have permission 777?
Any solution ?
The problem is yours not mine, I’ve told you the code it’s failing on, it’s a standard php function. If that fails then I suggest you have a problem, but it is NOT the fault of image_moo. If you want full support then you can communicate via email and pay for support, but the issue is yours not mine.
Thank you , i did it 🙂
Care to share your solution?

Hi, i’m having trouble by using your library. After loading the library I get ‘Undefined property: Image_moo::$error’, not being able to see the actual error of why My image is not being resized. I just copyied the example an it’s throwing this… any idea?
Line number or anything? there is no error, only errors which is an array.
Thx man, I will wait for new version! Great job!
Hi there, im trying use the save_dinamic, but i only see squads, how i proceed?
Thx again
I replied to your post on the CI forums 🙂
Thx, the saga continues there!! ^^
Rly thks man.
Very good stuff ! Thanks for this good library.
Hi
I’ve downloaded the library, but I’m getting errors when loading from a view
$this->load->library(“image_moo”);
$this->image_moo->load(“../images/img01.jpg”);
A PHP Error was encountered
Severity: Notice
Message: Undefined property: CI_Loader::$image_moo
Filename: views/vista_datos_cuenta.php
Line Number: 270
Sorry for the delay (See my post about not being able to access WP-Admin!)
In CI you don’t normally do work in the view itself, the view is just that. What are you trying to achieve?
Thank you for this super library! I found it on Google, and it is exactly what I am looking for.
Thanks again!
Im getting “Function ereg_replace() is deprecated” when i do
$this->image_moo->check_gd();
Am I doing something wrong?
Yep, fixed for the next release, will try and get it on tonight 🙂
Great library mate. Saved plenty of time!!!
This library looks pretty good – I was looking for something like this but with a bit more functionality (flip horizontal, vertical, text with stroke). Would you consider putting the library on github so that I (and others) can fork it, make changes and send you any pull requests for you to review?
Adding flip is pretty easy, just never had a need for it myself 🙂 In terms of text with stroke, is that for watermarking? For now I’d rather keep the library hosted on here, you are free to do what you want with it though.
Thanks very much for this library – just one question, can it retain PNG transparency after resizing?
Not sure, why don’t you try it out and let me know 🙂 On another note I have a small update I need to upload soon.
I have tried this out and it doesn’t seem to work each resized png with transparency gets a black background.
Also trying to reset the background to white I still get a background colour of black 🙁
Great library but would be great if you could work in support for this.
I have made some improvements on this, but I haven’t had time to finish testing it. The black background is due to the alpha channel and the code not correctly processing alpha channels (mostly I use it for jpegs). I’m rather constrained for time at present, but I will at some point put an improved version up.
PS See http://codeigniter.com/forums/viewthread/161469/P40/#886580
Greatjob dude. Keep it up.
this is a nice library, can i use this outside CI?
I’ve not tried, but I don’t think it would take too much to get it work outside of CI.
Thank you very much, amazing job…

Well you would need to crop->curve->shadow, but with the current code the shadows are restricted to square only. I do have an idea on how to improve this, but not the time to implement it at the moment, sorry.
I guess you could, it just seems kind of strange 🙂
What’s strange is that you are pointing out a flaw that isn’t even one.
Great work!!
One thing this Library really needs is the ability to have it resize() to just the width or just the height.
Basically the way this works is you have resize(200,0) so what it is saying is that it will NOT try to match the height, it will only focus on matching the width (and constrain proportions). Here is a script that uses this idea http://tech.mikelopez.info/2006/03/02/php-image-resize-script/
Could you not just call resize(200,9999) should cover most options?
This is simply amazing! I have a quick question. For the padded crop, is there a way we can only add padding to one direction of the image (e.g., add padding to the right of an image)? I’m trying to add a one sided pad and a watermark on the right of an image.
Thanks!
Hmmmm. Would it not be better to just resize then pad as needed using css?
Hi,
i have problem with image quality after saving :
$this->image_moo ->load($upload_path . $file_name)
->load_watermark(“wm.png”) ->set_jpeg_quality(100)
->watermark(3,TRUE)
->save($original_path . $file_name);
i set set_jpeg_quality to 100, but the result is same image quality and bad wotermark quality …
how to set watermark image quality to 100%.
Thanks in advance and sorry for my bad english
Hi Pavel,
Can you send me a copy of the files to play with? (I’ll email you)

First off thanks for the library, it is a great improvement on the default CI library and saves us a ton of time.
One thing I noticed when I ran a pretty fringe case was I don’t think you calculate the new dimensions quite correctly int he resize method On line 511 you check to see if the image width is greater than the image height. If it is then you use the crop width as the new width. However this doesn’t always yield the proper results take for instance this example:
max_h = 200
max_w = 1000
image_h = 300
image_w = 400
new_h = 750
new_w = 1000
however if you change line 511 to check the ratio to decide which should be max you will always keep it within the bounds of max width and max height
if( $this->width / $this->height > $mw / $mh ) {
Good spot, I’ll test that out and update! Would of course need some odd parameters for this to happen but it is possible
The way I was running it I wanted to make sure it only resized based on width so I had set the height to a ridiculously high number. Thats really the only way I can think of it happening.
good job man..
ur library saved my time!
thanks
Your welcome!
Hi, how can I crop image, if i have only 2 coordinates: x_axis and y_axis in CI´s Image Manipulation Class. image_moo requires 4 parametres: x1,x2,y1,y2. Thank you.
CI Image lib also requires 4 params, X, Y, Width, Height… So crop($x,$y,$x+$width,$y+$height)
Where on earth $newfile came from, I have no idea! LOL, thanks 🙂 Glad you like it.
The save_pa function is still broken. The error is now in line 237:
Original:
$this->save($newfile,$parts[“dirname”].’/’.$prepend.$parts[‘filename’].$append.’.’.$parts[“extension”], $overwrite);
..should be:
$this->save($parts[“dirname”].’/’.$prepend.$parts[‘filename’].$append.’.’.$parts[“extension”], $overwrite);
Anyway, great lib and works like a charm(after the bugfix) 🙂
Really good library, thanks
This looks excellent! Thanks!
Although I found a minor bug in save_pa function. Line 233 should probably say:
$this->save($parts[“dirname”].’/’.$prepend.$parts[‘filename’].$append.’.’.$parts[“extension”],$overwrite);
Thanks, fixed and will upload soon.
