setrop2
This function is used to set current binary raster operation mode.
void setrop2(int mode);
Parameters
mode
Binary grating operating code. This function supports all 16 binary grating operator codes, as listed below:
| Value | Description |
|---|---|
| R2_BLACK | The drawn pixel color is black. |
| R2_COPYPEN | The drawn pixel color is the current color (default). |
| R2_MASKNOTPEN | The drawn pixel color is screen color AND (NOT current color). |
| R2_MASKPEN | The drawn pixel color is screen color AND current color. |
| R2_MASKPENNOT | The drawn pixel color is NOT screen color AND current color. |
| R2_MERGENOTPEN | The drawn pixel color is screen color OR (NOT current color). |
| R2_MERGEPEN | The drawn pixel color is screen color OR current color. |
| R2_MERGEPENNOT | The drawn pixel color is NOT screen color OR current color. |
| R2_NOP | The drawn pixel color is screen color. |
| R2_NOT | The drawn pixel color is NOT screen color. |
| R2_NOTCOPYPEN | The drawn pixel color is NOT current color. |
| R2_NOTMASKPEN | The drawn pixel color is NOT (screen color AND the current color). |
| R2_NOTMERGEPEN | The drawn pixel color is NOT (screen color OR the current color). |
| R2_NOTXORPEN | The drawn pixel color is NOT (screen color XOR the current color). |
| R2_WHITE | The drawn pixel color is white. |
| R2_XORPEN | The drawn pixel color is screen color XOR current color. |
Attention：
- AND / OR / NOT / XOR for Boolean operations.
- "Screen Color" refers to the color of the screen pixels that are drawn.
- "Current Color" refers to the color to be drawn.
Return Value
None
Remarks
The binary raster operator mode set by this function affects only the output of lines and fills, including IMAGE fills, and does not affect the output of text and IMAGE.
