putimage
This function is used to draw the specified image on the current device.
// Draw an image
void putimage(
int dstX, // X coordinates of the draw position
int dstY, // Y coordinates of the draw position
IMAGE *pSrcImg, // Image object pointer to draw
DWORD dwRop = SRCCOPY // Three-element grating operating code
);
// Draw an image (specifying width and start position)
void putimage(
int dstX, // X coordinates of the draw position
int dstY, // Y coordinates of the draw position
int dstWidth, // The width of the draw
int dstHeight, // The height of the draw
IMAGE *pSrcImg, // Image object pointer to draw
int srcX, // Draw the upper-left x coordinates of the content in the IMAGE object
int srcY, // Draw the upper-left y coordinates of the content in the IMAGE object
DWORD dwRop = SRCCOPY // The three-element grating operating code
);
Parameters
See notes in function prototypes.
Remarks
The three-element grating operating code (bit operating mode) supports all 256 kinds of three-element grating operating codes, which are commonly used as follows:
Value | Meaning |
---|---|
DSTINVERT | Destination image = NOT Destination image |
MERGECOPY | Destination image = Source image AND Current fill color |
MERGEPAINT | Destination image = Destination image OR (NOT Source image) |
NOTSRCCOPY | Destination image = NOT Source image |
NOTSRCERASE | Destination image = NOT (Destination image OR Source image) |
PATCOPY | Destination image = Current fill color |
PATINVERT | Destination image = Destination image XOR Current fill color |
PATPAINT | Destination image = Destination image OR ((NOT Source image) OR Current fill color) |
SRCAND | Destination image = Destination image AND Source image |
SRCCOPY | Destination image = Source image |
SRCERASE | Destination image = (NOT Destination image) AND Source image |
SRCINVERT | Destination image = Destination image XOR Source image |
SRCPAINT | Destination image = Destination image OR Source image |
注:
- AND / OR / NOT / XOR for Boolean operations.
- Current fill color refers to the color that is set by setfillcolor for the current fill.
- See all the ternary raster operation codes here: Ternary raster operations.
Return Value
None
Examples
The following snippet copies the 100x100 image from the start of the screen (0,0) to the (200,200) position:
IMAGE img;
getimage(&img, 0, 0, 100, 100);
putimage(200, 200, &img);
