Poor image quality - to much compression

Poor image quality - to much compression

Thursday 17 March 2005 3:08:33 pm - 12 replies

I run eZp v.3.5-1 and every image I load into the admin gets compressed to death. I've got both GD and ImageMagick on my system. Think it's the latter one who's active and causing the blurry images.

Probably an easy task but how do I reduce imagecompression in settings?

Hi Valentin,

Look in to settings/image.ini file. There you can change image settings like quality, size, etc

Hi Lukasz, thanks for quick reply: I know about the image.ini override in my siteaccess, but this file has grown more advanced since prior versions of eZp. Would be great if u guys could be a bit more specific in which parameters to tweak. Thanks! blunk.gif Emoticon

This might be what you are looking for in image.ini

[MIMETypeSettings]
# Set JPEG quality from 0 (worst quality, smallest file) to 100 (best quality, biggest file)
Quality[]=image/jpeg;75

Thanks for your input, but I've tweaked this one without any effect. Seems like some other setting is overriding imagecompression..

Perhaps there is a way to avoid any compression if image file is less than say 50 Kb?

I ran into exactly the same problem, did you find a solution to increase the image quality ?

Dirk, set the image quality as pointed out by Hans-Henry Jakobsen to a higher value in both image.ini and/or any image.ini override. Also using imagemagick, check if it's enabled, instead of GD will give you better/sharper images.

Hi, I'm still not satisfied with my image quality. Seems like eZ is compressing them to death. Here's my image.ini-settings. I would be very thankful for any hints.

As posted here:
http://www.ez.no/community/forum/...always_creates_png_but_i_do_need_jpg

I do also have quality problems with png images that were generated with the "image()" funktion.

Perhaps it is the same problem!

Hi there..

I have the same problem. I tried the various tips here, but no change can be seen..

I tried GD and I tried ImageMagick.

Is there a way to turn of compression, i.e. only make the various sized version with the same compression as the original?

Me too. Has anyone had any success with this?

I am making a website for a firm that makes bathroom furniture, and blurry, overcompressed images is no good way to persuade the public to buy their stuff!

I have changed the settings in the override with no success. I run version 3.5.6 and (currently) GD.
