Image library (GD) resize problem - El Forum - 02-22-2009

[eluser]RaBu[/eluser]
Hi,

I'm trying to re-size a newly uploaded image-file in a controller function, I get no errors and the image get re-sized just fine, but the quality is crap. The image get very dusty and with a low amount of colors (in the blue-, gray-, white-ish scale).

Code:
$imageconfig['image_library'] = 'GD';

$imageconfig['source_image'] = "uploads/".$uploadFiles['0'];

$imageconfig['quality'] = "100%";

$imageconfig['maintain_ratio'] = TRUE;

$imageconfig['width'] = 250;

$imageconfig['height'] = 150;

$this->load->library('image_lib', $imageconfig);

$this->image_lib->resize();

Anyone else have experienced this problem?

Kind regards,
Rasmus

Here you can see an example of the re-sized files:

Quote:$imageconfig['quality'] = "100%";

did you try and take out the % from 100%?

in the code there is no percent sign, and since text won't convert to an int very easily it'd get converted to 0 i believe.

Code:
class CI_Image_lib {

    var $image_library        = 'gd2';      // Can be:  imagemagick, netpbm, gd, gd2

    var $library_path        = '';

    var $dynamic_output        = FALSE;    // Whether to send to browser or write to disk

    var $source_image        = '';    

    var $new_image            = '';

    var $width            = '';

    var $height            = '';

    var $quality            = '90';

Yes, I have the exact same problem - even if I completely leave out the "quality" parameter.

Are you sure you are using GD instead of GD2 ?

Of course, my phpinfo() says:
GD Version: bundled (2.0.28 compatible)

So changing to GD2 fixed the problem.

Code:
$imageconfig['image_library'] = 'GD2';

Thanks for the pointer Smile

I had the same exact problem... even after switching to GD2 it was still doing it!

Solved by adding the line to my config:

$config['quality'] = '90';

Hope this helps someone else running in to this problem.

I was there done that. basically forget about GD and GD2 if quality of images are important to you. use imagemagick instead.
