L_LTKRN_API L_INT L_PutBitmapRowCompressed(pBitmap, pWorkBuffer, pRunBuffer, nRow, nLines)
|
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
|
L_UCHAR* pWorkBuffer; |
/* pointer to a work buffer */ |
|
L_UINT16* pRunBuffer; |
/* pointer to the source buffer */ |
|
L_UINT nRow; |
/* number of the first row to update */ |
|
L_UINT nLines; |
/* number of the rows to update */ |
Puts one or more rows of 1-bit compressed data from a buffer to a bitmap that is maintained in its compressed format.
|
Parameter |
Description |
|
pBitmap |
Pointer to the bitmap handle referencing the bitmap to copy the rows into. |
|
pWorkBuffer |
NULL or a pointer to an optional work buffer. Allocating the work buffer speeds processing if you call this function more than once, because if you do not allocate a work buffer, the function allocates and frees a temporary buffer each time it is called. The size of this buffer should be the same as the bitmap handle's BytesPerLine field. |
|
pRunBuffer |
Pointer to the input buffer, which contains 1-bit compressed image data. |
|
nRow |
Number of the first row to update. |
|
nLines |
Number of rows to update. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
This function is useful for working with 1-bit images that are loaded in their compressed formats for faster loading and display. For more information, refer to Speeding Up 1-Bit Documents.
