The Source may transfer the data in a different format--the information may be transferred in "strips" or "tiles" in either compressed or uncompressed form. See the TW_IMAGEMEMXFER structure for more information.
The term "sample" is referred to a number of times in this structure. It holds the same meaning as in the TIFF specification. A sample is a contiguous body of image data that can be categorized by the channel or "ink color" it was captured to describe. In an R-G-B (Red-Green-Blue) image, such as on your TV or computer's CRT, each color channel is composed of a specific color. There are 3 samples in an R-G-B; Red, Green, and Blue. A C-Y-M-K image has 4 samples. A Grayscale or Black and White image has a single sample.
Note: The value -1 in ImageWidth and ImageLength are special cases. It is possible for a SourcetonotknoweitheritsWidthorLength. Applicationsneedtoconsiderthiswhen allocating memory or otherwise dealing with the size of the Image.
