This function is called by the LMemoryFile::SaveFileBuffer function to save the specified image data.
#include "ltwrappr.h"
virtual L_INT LMemoryFile::SaveFileCallBack(pLBitmap, pLBuffer, uRow, uLines)
Pointer to an LBitmapBase object that contains the image data.
Pointer to an LBuffer object into which the bitmap will be saved.
Number of the first row of data that the callback will write to the buffer.
Number of lines that the callback will write to the buffer.
Value | Meaning |
---|---|
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
If this function is overridden, the user must supply the image data that the function will save. The base class implementation saves data from the class object's associated bitmap.
This function does not support signed data images, unless they are DICOM images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image that is not a DICOM image is passed to this function.
Win32, x64.
