Transparent gif backgrounds rendered black

omike · Post by **omike** » 29 Apr 2008, 18:20

Hi, I'm loving Phoca Gallery so far--easy to install and use. The only problem I'm having is with transparent gifs. Both the thumbnails and the full size pictures have their backgrounds converted to black.

Is there anyway to preserve the transparency?

Using Joomla 1.5.3 and Phoca 1.7.0

Hi, the thumbnails creating is made from GD function which is a part of your PHP... I think, there is no way to change it but I take a look at it...

Ok that makes sense that it's a limitation of GD for the thumbnails. My next question is that it seems as though the full size versions of the images are also being processed by GD. When I click on the thumbnail, the full size image also has the black background. Looks like the file that is being displayed in full view is named "phoca_thumb_l_originalname.gif." Is it possible to have it display the original graphic, rather than the processed graphic?

there is:

small size - backend displaying
medium size - frontend, backend displaying
large size - frontend (detail), backand displaying...
original size - fronten (download displaying)...

Hi think, it is not good idea to display the original image in detail view... Many users have the original image with 3 MB ... Do you think, you will wait for seeing the 3 MB image in detail view or in slideshow...

Hi, I see what you are saying, that it wouldn't be a good idea to show the original image. In my case, it would work better since then my transparent gifs wouldn't have the black background. My images are all resized prior to uploading, so I wouldn't have the problem of a 3MB graphic being displayed.

So is there a way to have it display the original graphic? I don't see that option in the Gallery. Thanks!

Original size: if user click on download link (In Parameters you can set if it will be displayed or not)
