png transparency not working?

[jed]

Hi I'm loading an imageset that uses a png file. I'm using it as a sprite essentially so I don't want it drawn as a simple square. The png has transparency turned on. the png shows up with the correct transparency in photoshop.
I call Image::draw()
the image appears but rather than the area marked transparent being see through it is white. Do I need to do something other than call Image::draw to get it to work correctly?

Transparency doesn't seem to work with gifs either.

Here is a simple example:

Code: Select all

CEGUI::Imageset* unitImages=CEGUI::ImagesetManager::getSingleton().createImageset("units.imageset");

MouseCursor::getSingleton().setImage("units","cursor");


The cursor becomes a white block with the image. Do I need to call something else?

Strange, as for me it seems to work (drawing transparent png's). You could try to display that image in a StaticImage to see if it's CEGUI having problem with your image or your drawing code having problems.

There are more people having the problem that their images are showing up white. Wonder what it is.

StaticImage doesn't work either. The png is definitely transparent, it works fine in a webpage. Do you think it needs a specific bit depth of png? Could someone send me a png that works for them?

Also I just tried it as a .tga and it works fine.

Ok, it's sure that it is the png file. This picture works for me.

I have the same problem. Does anyone have any ideas?? I have also tried the suggestion from this thread.

Witch renderer do you use ? Witch image loader library do you use ?
Do you also have the same problem with the TaharezLook.tga file ?

Ogre Renderer - Found out it just uses Built in D3D file loading. The problem was something else un-related. Thanks.
