L_LTIMGCOR_API L_INT L_GetMarksCenterMassBitmap (pBitmap, pMarkPoints, pMarkCMPoints, uMarksCount, uFlags)
Finds the center of mass for each of the registration marks specified by pMarkPoints.
Pointer to the bitmap handle referencing the bitmap to be used in center of mass computation.
Pointer to an array of points containing mark locations.
Pointer to an array that will be filled with points which represent the center of mass for each of the supplied registration marks. The first center of mass point corresponds to the first registration mark in the
pMarkPoints array and so on
Number of marks, must be 3.
Reserved for future use. Must be 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
This function is used to determine the center of mass for each supplied registration mark, to be used in detecting image rotation, scaling and translation.
The results (that is, the points representing each center of mass) returned by this function are multiplied by 100 in order to obtain more precision (00.00). To get the actual results, divide by 100.
This functions uses values that are divided internally by 100.
This function can be used in the following manner:
This function does not use L_SetStatusCallback.
If you simply want to automatically straighten a bitmap, use the L_DeskewBitmap function.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in the Document and Medical Imaging toolkits.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.
