Hi Galfar,

  thank you so much for the prompt reply. I'll try to implement.  :)

Best regards,

Hi, it should be quite easy to convert TImageData to CMBitmap:

CMBitmap.image is TImageData.Bits
Width and Height is easy
CMBitmap.pixelSize is 8 * Fmt.BytesPerPixel (use GetImageFormatInfo function to get this)
CMBitmap.rowBytes is Width * CMBitmap.pixelSize

Then you need to set CmBitmap.space according to TImageData.Format,
mostly cmRGB24Space or cmRGBA32Space is used.

Hi,

  I'm using Lazarus (Mac OSX) and the Vampyre library. I'm trying to find out how to use the colorsync for color conversion with icc profiles.  :'( The mac colorsync API function "CWMatchBitmap" needs CMBitmap. Does Vampyre provides a function for converting TImagingBitmap/TImageData to CMBitmap? if not how can do the conversion to CMBitmap?

The structure/record of CMBitmap is definded in Lazarus as following:

CMBitmap = record
image: CStringPtr;
width: size_t;
height: size_t;
rowBytes: size_t;
pixelSize: size_t;
space: CMBitmapColorSpace;
user1: UInt32;
user2: UInt32;


Thanks!  :)
