Alpha channel set to zero
Cool design! I load a GIF (non-animated, single frame), where there is no transparency. Preview looks great. Export RGB32 shows the alpha channel set to zero. (every value shows like $001E1915 as an example). While I can ignore this in code, I really wanted RGB565 output. So, if you select that, you get all zeros (no image data). Perhaps I'm doing something wrong. I've attached the GIF if that helps. For now, I'll load the 32-bit data, force the alpha channel to 0xFF, and do the RGB565 conversion in code (but it doubles the code size and slows painting the image).
Hi, sorry for the delay and thanks for the bug report.
I suspect that's a bug, I'll try and get a fix out today :)
No problem. I’ve attached an image if it helps. It was created in Photoshop, and I first inserted a black background, and then when creating the GIF, I turned off transparency.
I know you likely hate feature requests 😊, but option I’d love to have is output the image file as a C++ array of hex bytes (all bytes, no conversion). It makes for a small array in a byte limited controller. It does requires more decoding code on my end, but not a huge deal.
Best regards,
Frank.

Thanks for the extra information. I'm working on it now. I'll hopefully have a fix today or tomorrow :)
