[VB6] - DIB's how change the array dimensions

i read several tutorials about DIB's and every them have their way on building arrays(1D,2D,2D+RGB).

we can create arrays with any dimensions:

Code:

ReDim ImageData(0 To ByteAlignOnWord(24, bm.bmWidth) - 1, 0 To bm.bmHeight - 1)

and i know use GetDIBits() api function:

Code:

GetDIBits SrcPictureBox.hDC, SrcPictureBox.Image, 0, bm.bmHeight, ImageData(0, 0), bmi, 0

my problem is: how i know that GetDIBits() put only the colors or the RGB colors?
(the tutorials,that i found, don't explain these question... i did with 2D array sample, but we can do with 1D or even with 3D. but the tutorials don't explain how do these... can anyone explain to me?)
