Transparency lost in GIF files

Post by rmcmanamy » Wed Dec 09, 2009 1:47 pm

Even in the sample app if you load a gif file with transparency and resave it the transparency is lost. Is this a bug in the toolkit or are we missing setting an output parameter or something in the save process?

GIF files don't support alpha channel transparency. Please use other file format (PNG...)

But gif files do support picking a single color to be the transparent color. Shouldn't this feature be brought through and saved in a gif file? Most image editing software as well as web browsers support it.

Hey Rodney,

Just to confirm is this related to Image XChange ver3 or 4?
As if it's ver3 I am afraid we would not be able to do much.

And is .png not a viable solution?

Best,
Stefan

Sorry, it would be for Version 4 now. We had found a workaround but in the case we were working on at the time it was for gif images and we had to output as a gif again.

Ok so we will consider the initial case closed, and I will see what our dev guys have to say about gifs with transparent colour and our Image XChange SDK.

Best,
Stefan
