You've got me interested. I (finally) took a look at the splash.rgb file...
I don't have kde, but I do have imagemagick installed, and using # identify -verbose I get a long list of technical specs, that only differ from bo105-splash.rgb or danube-splash.rgb in a couple areas: Image: an2-splash1.rgb Format: SGI (Irix RGB image) Class: DirectClass Geometry: 512x512+0+0 Type: TrueColorMatte (Type: TrueColor in bo105) Endianess: Undefined Colorspace: RGB Channel depth: Red: 8-bit Green: 8-bit Blue: 8-bit Alpha: 8-bit Alpha: 1-bit in danube, and 0 bits in bo105 Channel statistics: Red: Min: 0 (0) Max: 255 (1) Mean: 53.1742 (0.208526) Standard deviation: 75.8434 (0.297425) Green: Min: 0 (0) Max: 255 (1) Mean: 66.2499 (0.259804) Standard deviation: 79.7865 (0.312888) Blue: Min: 0 (0) Max: 255 (1) Mean: 84.0289 (0.329525) Standard deviation: 82.9706 (0.325375) Alpha: Min: 255 (1) Max: 152 (0.596078) Mean: 254.998 (0.999993) Standard deviation: 0.403287 (0.00158152) Colors: 40641 Colors: much less in other files Rendering intent: Undefined Resolution: 72x72 Units: Undefined Filesize: 467.566kb Filesize: not the largest seen Interlace: None Background color: white Background: black in bo105 Border color: rgb(223,223,223) Matte color: grey74 Transparent color: none Page geometry: 512x512+0+0 Dispose: Undefined Iterations: 0 Compression: RLE [snip] I tried loading it in Gimp, and saving in the same manner I have created the other rgb via sgi files, as I commented last week from the documentation. It didn't work. Still SegFaults with error 11. So, since the Alpha channel is the biggest difference, I tried Flattening the image, and it loads! Conclusion: 1-bit alpha is supported. 8-bit alpha is not. Hey, nice picture Yurik!

That's an interesting detail I don't know about.
