Hi there

I'm seeing this PHP error coming from class Image_Transform_Driver_GD:

Warning: imagecolorsforindex() [function.imagecolorsforindex]: Color index 255

It's thrown at line 602. And I can guess why. Some GIF images can have a transparency index higher than 255, especially when animated.

So I recommend you to obtain the palette size first with imagecolorstotal(), here a good example:

Thanks for the bug fix, cheers :)

Description:

package.xml currently lists the role for example files as "php", 
but it may be better to have them listed as "doc" so they don't 
get installed into php_dir. "doc" role for example files seems to 
be the norm for most packages.

Image_Transform: Bug 18592 [Open] Imagick3 compression quality

PHP: 5.3.1 OS:  Package Version: 0.9.4

Description:
------------
I found some issues related to "quality" parameter in Image/Transform/Driver/Imagick3.php class :

First of all, the "setImageCompression" method is mistakenly invoked to set Quality, when it should rather be a call to "setImageCompressionQuality" method...

Also, I noticed that when generating thumbnails, resulting files are much bigger than corresponding GD picture (same quality parameter) ?!? To solve that, I discovered that a call to Imagick::stripImage() would clean extraneous data...


Test script:
---------------
Replace :

$this->imagick->setImageCompression($quality);

By :

$this->imagick->setImageCompression(Imagick::COMPRESSION_JPEG);
$this->imagick->setImageCompressionQuality($quality);
$this->imagick->stripImage();

PHP: 5.3.4 OS: CentOS Package Version: 0.9.3

Description:
------------
When script is called on certain images, errors occur.

Error checking should be improved so that the functions in the 
package calling imagecopyresampled() and imagecopyresized() 
check for potential problems and return a (descriptive) error 
before the function is called.

Test script:
---------------
load($file);
  $i->setOption('quality','100');
  $i->setOption('scaleMethod','smooth');
  $i->fit($width,$height);
  $i->save($file,'jpeg');
?>

Expected result:
----------------

1. Resize image

"You have already resized the image without saving it. Your previous resizing will be overwritten" and save file is not resized :(

I used GD driver and functions "display" and "save" don't have $this->resized = false;

In IMLIB driver functions "display" and "save" have $this->resized = false;

Test script:

$i = &Image_Transform::factory('GD');
$i->keepSettingsOnSave(true);
$i->load($_o_file);
$i->scaleByX($start_x);
$i->save($_n_file, 'jpg', 90);

 GD.php:486   $this->imageHandle = $this->oldImage;

 it probably has to be the opposite
 $this->oldImage =  $this->imageHandle;

else the resource handle is lost unless you've called manipulation functions before and they have set  $this->oldImage

I need a function which returns the image as string for inserting it into a database.
Although it would be possible to save the file and then use get_file_contents(), it would be much nicer to directly get the image as a result from a function, e.g. $content = $image->getFile();

Enhaned version of fit()...
two additional parameters are required:

$exactly (bool) - determines wether the image must have the 
exactly (!) the size as specified by the $width and $height 
parameters

$keepasprect (bool) - determines whether the aspect ratio of 
the orginal image is mainted or not

Test script:
---------------
My version of the fit() function:

    function fit($width, $height, $exactly=false, $keepaspect=true)
    {
        if ($width <= 0 || $height <= 0) {
            return PEAR::raiseError("Invalid arguments.",
                IMAGE_TRANSFORM_ERROR_ARGUMENT);
        }

        $x = $this->img_x / $width;
        $y = $this->img_y / $height;
 		
		if ($exactly == false) {
			if ($x <= 1 && $y <= 1) {
	            return true;
			} elseif ($x > $y) {
	            return $this->scaleByX($width);
	        } else {
	            return $this->scaleByY($height);
	        }
		} else {
			if ($keepaspect == false) {
				return $this->resize($width, $height);
			} elseif ($x == $y) {
					return $this->scaleByX($width);
			} elseif ($x > $y) {
				$res = $this->scaleByX($width);
				if (PEAR::isError($res)) {
					return $res;
				} else {
					return $this->crop($width, $height, 0, round(($this->img_y-$height)/2, 0));
				}
			} elseif ($x < $y) {
				$res = $this->scaleByY($height);
				if (PEAR::isError($res)) {
					return $res;
				} else {
					return $this->crop($width, $height, round(($this->img_x-$width)/2, 0), 0);
				}
			}
		}
    }

Expected result:
----------------
With the additial parameter, this function is perfect for 
creating thumbnails for example!

There may be bugs in my version of fit()

I wanted to suggest to insert this into the manual but we currently don't have documentation for Image_Transform. I don't know the correct PHPDoc syntax to paste this as an example:

$borderimage = Image_Transform::factory('GD');
$borderimage->load('mygraphicborder.jpg');

$imgtr = Image_Transform::factory('GD');
$imgtr->load('tmp/uploaded_image.jpg');
$imgtr->applyBorderImage($borderimage->imageHandle, 7, 7);
$imgtr->save('uploads/image_with_border.jpg', '', 90);
