Images quality (definition)

Tuesday 01 December 2009 9:43:07 am

Hello,

Using eZwebin, I have problems with the quality of images, especially the ones uploaded with "Image" attribute. Very bad quality, seems to be extremely compressed.

In the template, image is set with

{attribute_view_gui attribute=$node.data_map.image}

In the image.ini.append.php file, settings are :

[MIMETypeSettings]
Quality[]
Quality[]=image/jpeg;100

What can I do to have good quality images ?

Thanks Gaetano. I didn't know, then you gave a direction to look at. I put

{attribute_view_gui attribute=$node.data_map.image image_class=articleimage}

in the template to have load a different image variation. Indeed, myimage_articleimage.jpg is loaded, but quality is still bad. Original image size is 24 ko and myimage_articleimage.jpg is 5 ko... Quite an awful compression.

Hello Catherine,

Did you make sure that the 'articleimage' transformation (defined in image.ini) is not applying quality-degrading filters ? And what image processing backend are you using ? ImageMagick or GD ?

You may want to give us the details of the 'articleimage' filter btw.

Let us know,
