Detailed Description
A layer that allows you to have a bitmap image printed in the mpWindow.
Use SetBitmap() to load the image in the right place. You can retrieve the image from the layer at anytime you want with getBitmapCopy()
Member Function Documentation
◆ DoPlot()
|
protectedvirtual |
Pure virtual method to plot the layer.
Must be overridden and implemented by derived classes.
Implements MathPlot::mpLayer.
◆ SetBitmap()
| void mpBitmapLayer::SetBitmap | ( | const wxImage & | inBmp, |
| double | x, | ||
| double | y, | ||
| double | lx, | ||
| double | ly | ||
| ) |
Change the bitmap associated with the layer (to update the screen, refresh the mpWindow).
- Parameters
-
inBmp The bitmap to associate. A copy is made, thus it can be released after calling this. x The left corner X coordinate (in plot units). y The top corner Y coordinate (in plot units). lx The width in plot units. ly The height in plot units.
