Hello !

I’ve made a canvas using wxGraphicsContext and I need to print drawing I make with my canvas

How can I do it??
wxPrinterDC don’t work with wxGraphicsContext

wxGraphicsContext is still new and doesn't have printer support yet. The best that can be done currently is to render the context to a bitmap using a wx.MemoryDC and then print the bitmap using the normal print framework

yes it can be a good alternative
can you give me a example of the use of wx.MemoryDC ? because I’ve tried to render into a memoryDC and then blit it on the printerdc but it didn’t work

thank you

You can try using DrawBitmap instead of blitting. Maybe something like this:

  bmp = wx.EmptyBitmap(width, height)
  dc = wx.MemoryDC(bmp)
  self.DoDrawing(dc)
  del dc

  printerDC.DrawBitmap(bmp, 0,0)

thanks you, it works !

I have do this :

bmp = wx.EmptyBitmap(width, height)
dc = wx.MemoryDC(bmp)
dc.SelectObject(bmp)
self.DoDrawing(dc)

printerDC.DrawBitmap(bmp, 0,0)

(dc)
del dc

    printerDC.DrawBitmap(bmp, 0,0)
