virtual void mrpt::utils::CEnhancedMetaFile::setPixel | ( | int | x, |
int | y, | ||
size_t | color | ||
) | [virtual] |
Changes the value of the pixel (x,y).
Pixel coordinates starts at the left-top corner of the image, and start in (0,0). The meaning of the parameter "color" depends on the implementation: it will usually be a 24bit RGB value (0x00RRGGBB), but it can also be just a 8bit gray level. This method must support (x,y) values OUT of the actual image size without neither raising exceptions, nor leading to memory access errors.
Implements mrpt::utils::CCanvas.

int | y0, | ||

) | [virtual] |
Places a text label.
x0 | The x coordinates |
y0 | The y coordinates |
str | The string to put |
color | The text color |
fontSize | The font size, in "points" This method may be redefined in some classes implementing this interface in a more appropiate manner. |
