Mirrored Image #12

Closed snap2222 closed 7 years ago

snap2222 commented 8 years ago

Hi Henner, I have my display working great except the image is mirrored. Is there a solution?

Thanks.

You could write a transformer and hook it into the transformer chain or simply modify the call to SetPixel() with the appropriate math (e.g. if it is mirrored in X direction, then you would say SetPixel(draw_canvas->width() - x, ...)

In both cases you need small modifications in the source.

May be beyond my ability, but I will certainly give it a try! Damon
