I need to display a GeoTIFF image as a Windows bitmap using CreateBitmap API.
But I notice that the image is inverted vertically. I read in tiff2dib.c that in the tiff file, the lines are saved from up to down and in a DIB, the lines must be save from down to top. Does that means that when creating my bitmap, the bits from the TIFF image should be inserted bottom-up?
Windows and OS/2 DIBs are stored with bottom-to-top scanline ordering. Under Windows you can use a negative value for the DIB height to achieve top-to-bottom ordering.
