Appends boxes of eBoxType to the file in buffer. This function is available in the Document/Medical Toolkits.
Parameter |
Description |
pBuffer |
Pointer to a JPEG 2000 file in the memory. |
uBufferSize |
Size of the JPEG 2000 file in bytes. |
lpOutBuffer |
Pointer to a pointer to be updated with an array of bytes that contains a JPEG 2000 file with new appended boxes. You must free this buffer by calling the Windows LocalFree() function. |
puOutBufferSize |
Address of a variable to be updated with the size of the output memory buffer in bytes. |
eBoxType |
Type of the boxes to be appended. |
pBoxes |
Point to an array of boxes of type eBoxType. |
uNumOfBoxes |
Number of boxes in the array. |
