L_INT LImageViewerCell::SaveRegion(pFileName, nSubCellIndex, nStartPage, uFlags)
Saves the region of the specified cell or sub-cell image to a file.
Character string that contains the name of the file to save.
A zero-based index into the image list attached to the cell. This sub-cell contains the image region that will be saved. Pass -2 to refer to the selected sub-cell. If the cell contains 1 frame then the nSubCellIndex should be 0.
The page number of a multipage file, which can contain more than one image.
Flag that is used to determine the way of saving the region. Possible values are:
| Value | Meaning |
|---|---|
| CONTAINER_FILE_CREATE | [0x00000000] Create a file. |
| CONTAINER_FILE_APPEND | [0x00000001] Append an existing file. |
| CONTAINER_FILE_REPLACE | [0x00000002] Replace the region in the index nStartPage in the existing file with the new region. |
| CONTAINER_FILE_INSERT | [0x00000003] Insert the region in the index nStartPage in the existing file. |
The following flags that determine whether to apply the feature on the one cell only, or more than one cell. This value can only be used when the cell is attached to the LImageViewer through the function LImageViewer::InsertCell. Possible values are:
| Value | Meaning |
|---|---|
| CELL_APPLYTOTHIS | [0x00000000] Apply the feature to this cell only. |
| CELL_APPLYTOALL | [0x10000000] Apply the feature to all the cells in the Image Viewer. |
| CELL_APPLYTOSELECTED | [0x20000000] Apply the feature to the selected cells in the Image Viewer. |
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
This function saves the region into an encrypted file. To load the saved region file use the LImageViewerCell::LoadRegion function.
Required DLLs and Libraries
This example will create a bitmap region on the first frame of the first image, save it, and then apply it to the rest of the frames.
