Image_moo

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.

    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 !!!

      Image paths can not load form a http location, you need the real file path where the image is stored.

    #13 written by Cahva 11 months ago

    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 :P

    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!

    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.

      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.

    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?

    • Mat-Moo
      #68 written by Mat-Moo 3 years ago

      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?

    • Mat-Moo
      #70 written by Mat-Moo 3 years ago

      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.

    this is a nice library, can i use this outside CI?

    • Mat-Moo
      #76 written by Mat-Moo 3 years ago

      I’ve not tried, but I don’t think it would take too much to get it work outside of CI.

    hi !! I have a question

    i need to crop image + make shadow + curve image

    but your lib create image crop image buy shadow not curve
    please help me Y Y

    • Mat-Moo
      #79 written by Mat-Moo 3 years ago

      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.

  • David Arnold
    #82 written by David Arnold 3 years ago

    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/

    • Mat-Moo
      #83 written by Mat-Moo 3 years ago

      Could you not just call resize(200,9999) should cover most options?

  • Jonathan Saw
    #84 written by Jonathan Saw 3 years ago

    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!

    • Mat-Moo
      #85 written by Mat-Moo 3 years ago

      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 ) {

    • moomin

      Good spot, I’ll test that out and update! Would of course need some odd parameters for this to happen but it is possible

      • Cole Thorsen
        #90 written by Cole Thorsen 3 years ago

        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.

    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.

    • moomin
      #94 written by moomin 3 years ago

      CI Image lib also requires 4 params, X, Y, Width, Height… So crop($x,$y,$x+$width,$y+$height)

  • moomin
    #95 written by moomin 3 years ago

    Where on earth $newfile came from, I have no idea! LOL, thanks :) Glad you like it.

  • cahva
    #96 written by cahva 3 years ago

    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) :)

  • Matjaž
    #98 written by Matjaž 3 years ago

    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);

    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.

    Hello,

    public function index() {

    $file_path=’1.jpg’;
    $this->test($file_path);
    }

    public function test($file_path) {
    $this->load->library(‘image_moo’);
    $fonts=’mailrays.ttf’;
    $this->image_moo
    ->load(‘image/’ . $file_path)
    ->make_watermark_text(“MERGE TARE ?”, ‘fonts/’.$fonts, 20, “#160000″,10)
    ->resize(700,700)
    ->watermark(2)
    ->save_pa(”, ‘_thumb’, TRUE);

    return $this->image_moo->errors;
    }

    The name folder “image” was created in the root.
