PNGPixelRect can only handle Lum/RGB/RGBA [1/3/4 bpp] images for now

Hello,

I'm migrating to JOGL2 from JOGL1 and I have the following problem.

I load a PNG into a bufferedimage and then use it as a texture

BufferedImage thumbNail=ImageIO.read(new File(localPath+catalogPath+path + txtName));
AWTTextureIO.newTextureData(GLProfile.getDefault(),thumbNail, false));
And I get this exception.
java.lang.RuntimeException: PNGPixelRect can only handle Lum/RGB/RGBA [1/3/4 bpp] images for now. BytesPerPixel 8

Is there a Workaround ? I cannot resave all my PNGs
I did not have this problem in JOGL1

Thanks for your help

Hi

You could modify the buffered image so that it uses a supported pixel format. Which kind of PNG do you use? "BytesPerPixel 8" is weird.

Edit.: You're probably using grayscale or truecolor PNGs with 2 bytes per sample. You can simply drop the least significant byte so that it uses 1 byte per sample, i.e 4 bytes per pixel which is supported by JOGL.

Thanks !

You're welcome.
