While the PDF format has advanced support for different color spaces and rendering intents, the current PDF backend just uses DeviceRGB and whatever the default rendering intent is. I wonder if some kind of different color space or such setting would help - but this is a subject that I know almost nothing about, and the PDF support is so complex that I don't even know what the next reasonable step would be above just using DeviceRGB. Does the bluemarble image come with a specification or documentation that mentions a color space, or what the pixel values are supposed to mean, or how they are recommended to be rendered? > Another thing you can do is to modify the bluemarble that > comes with matplotlib using the gimp, as it is just an image file you can > edit easily. Starts looking like data cooking, tho' ;-) The fact is that different devices (displays, printers, projectors) have different gamuts, and unless there is a specified color space, a set of pixel values has no "right" mapping to the colors of the gamut (and even if the space is known, mapping out-of-gamut colors can be done in several ways). So I wouldn't call it "data cooking" if you are just trying to get a reasonable contrast in your visualization of some data that consists of values in some arbitrary space, although of course it will not be any kind of true-color image either. -- Jouni K.
