Indeed. I was giving a quickie approach for those who can't get to the proper aspect ratio. Realistically, starting with the correct DPI setting in Gimp is the best way to maximize your returns. While scaling with an SVG might seem logical, it indeed does not produce the best results. You must customize and touch up your palette specifically to your target size. There is no avoiding this. SVG will give you an approximation, but the antialiasing and such is directly related to your final output. Using a gradual crunch back to 16 colors will ultimately result in the best image, constantly checking your antialiasing and discarding color information as you go. > > Anyone tried to get a usplash to conform to a Gimp 16 color palette > > generated png?

Here are the steps I followed: 1) Obtain an optimum 16 color palette via careful scrunching. 2) Import the palette via Gimp's palette tool. 3) Scuttle the palette entries around in accordance with https://wiki.ubuntu.com/USplashCustomizationHowto?highlight=%28usplash% 29 4) Re-work the working image down to a 16 color palette based on the final palette (Mode shift option in Gimp). 5) Try to run 'pngtobogl usplash-artwork.png > usplash-artwork.c' 6) usplash-artwork.c results in an error with too many colors in the file.
