Image_Transform Bug

PHP: 5.2.5 OS:  Package Version: 0.9.3

Description:
------------
 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

Image_Transform: Feature/Change Request 7412 [Verified] Need function which returns image content

PHP: Irrelevant OS:  Package Version: 0.9.0

Description:
------------
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();

Image_Transform: Feature/Change Request 7405 [Open] Enhanced fit() function

PHP: Irrelevant OS:  Package Version: 0.9.0

Description:
------------
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);
