I met a problem when parsing WT_PNG_Group4_Image,
cause I'm using OpenGL texture to render the image, so I called WT_PNG_Group4_Image::data() function to extract the data from the object. But the display is not right, is this because the extracted data belongs to a PNG file?
I've checked the object's type, which is WD_IMAGE_PNG_EXT_OPCODE.
If it is the PNG data, does it mean I need to convert it to normal RGB data to correctly display?
Thank you very much!
