LoadPixmapRAW()?

For that matter why isn't there a PF_I16 pixel format?

Um, open the file, read the data into a pixmap.

LoadPixmapRAW()?

Keep in mind that there are many different .raw formats -- they vary between manufacturers and camera models. (Photoshop regularly updates its RAW plugin to support the new flavors)

I finally figured out raw is just binary data, unless you have some proprietary camera format, which defeats the purpose of a no-BS data format.

Here's a convenient function with safeguards:

	Function LoadRaw:Int(url:Object,data:Byte Ptr,width,height,bpp)
		Local stream:TStream
		Local size
		stream=ReadStream(url)
		If Not stream Return
		size=width*height*bpp
		If size<>stream.size() Return
		stream.readbytes data,size
		Return 1
	EndFunction

You could take dcraw and write a BlitzMax wrapper for it. ;-)
