CopyImage

CATResult CATImage::CopyImage ( const CATImage *  srcImg, CATImage *&  dstImg, CATInt32  xOffset, CATInt32  yOffset, CATInt32  width, CATInt32  height   ) [static] CopyImage() creates a new image of the same type as srcImg and stores it in dstImg. The data from srcImg is copied into a buffer owned by dstImg. Caller must call CATImage::ReleaseImage() on the returned image when done. This version allows you to specify offsets, width, and height of the data to copy into a new image. Parameters: srcImg  - source image to copy from dstImg  - uninitialized image ptr. Contains copy of srcImg on return. xOffset  - relative x offset for top-left of copy. yOffset  - relative y offset for top-left of copy. width  - width of destination image. height  - height of destination image. Returns: CATResult result code See also: CATImage::ReleaseImage() Definition at line 234 of file CATImage.cpp. References AbsWidth(), CAT_ERR_IMAGE_INVALID_SUB_POSITION, CAT_ERR_IMAGE_NULL, CAT_SUCCESS, CATASSERT, CATFAILED, CATRESULT, CreateImage(), fData, fHeight, fWidth, kBytesPerPixel, XOffsetAbs(), and YOffsetAbs().
