for Tianocore, use the latter only. Needs to be a 24bpp windows BMP, no
larger than the width of the screen and 75% of the height (the image is
centered 38.2% down from top as per BGRT spec). Gimp can be used too
but likely will have a pallette shift if a non B&W image used
Customer sent me a png image of the logo they want to use so have
manipulated it using ImageMagick to give it a black background and
convert it to a Windows 3.x format BMP at 24bpp. Not sure why but the
first go converting it to a Windows 98/2000 and newer format failed.
Is there any reason not to use both with TianoCore? Does the
CONFIG_BOOTSPLASH JPG file not spend long enough on screen to make it
worthwhile using? I tried putting a JPG image (400x400 pixels) into
Coreboot but jpeg_decode() didn’t like it and returned
ERR_HEIGHT_MISMATCH. I haven’t looked into the cause (and may not do if
it really isn’t needed).
