I have a graphical image with a yellow border that will be set as the transparent colour, which works but the issue I have is that the JPG compression is messing up the yellow and introducing different yellow shades.
I zoom in on the image I can see the shades and using flood fill set at 50%, it changes these to the yellow colour I need (0x00FFFF01) but as soon as I hit save, the yellow shades appear. This happens in the VS2022 editor and with Paint .NET so when I tried to draw this I see yellow dots all around the image instead of just the middle section. This is the image.
Due to the file size and number of images, I cannot save as BMP.
