Hi,

I have this code:

Code:

if ($ds->loadImage($img_final)) {
   $ds->resizeToSize(125, 0);
   $cc->_imgOrig = $ds->_imgFinal;
    $cc->cropToSize(CROP_W, CROP_H, ccCENTRE);
   $cc->saveImage($img_mini);
    $cc->flushImages();
}


This works fine with JPG and GIF images, but when I try to upload a big PNG it doesnt save the image ($cc->saveImage($img_mini) )

Before adding the resizeToSize function and using only the CropCanvas class , it was working great.

Any help would be appreciated....thanks

Hi, and welcome to the board!

What are the sizes of CROP_W and CROP_H? If they are bigger then what your image ends up being then it will product an error. Is '$img_mini' set to a path location and is it writable? Does your GD installation have PNG support?

Try turning on debugging in the classes and see what messages it gives you when trying to process the png file.

Andy

125 and 125

Ok...But Ive deleted that line, and it doesnt work with this code:
Code:
if ($ds->loadImage($img_final)) {
   $ds->resizeToSize(125, 0);
   $cc->_imgOrig = $ds->_imgFinal;
   $cc->saveImage($img_mini);
    $cc->flushImages();
}


Is '$img_mini' set to a path location and is it writable?
Yes, because it works with jpg,gif and small png

Does your GD installation have PNG support?
Yes, because it works with small png

Sad

I was thinking in your post about the CROP_W and CROP_H, and Ive fixed it with this code Very Happy

Code:

if ($ds->loadImage($img_final)) {
   $ds->resizeToSize(125, 125);
   $cc->_imgOrig = $ds->_imgFinal;
    $cc->cropToSize(CROP_W, CROP_H, ccCENTRE);
   $cc->saveImage($img_mini);
    $cc->flushImages();
}
