imagetools.py: bugfix for lv.canvas() #169

Closed PGNetHun closed 3 years ago

PGNetHun commented 3 years ago

If PNG decoder is initialized (using imagetools.py), then lv.canvas() throws AttributeError: 'NoneType' object has no attribute '__dereference__' exception in this line: png_header = bytes(lv.img_dsc_t.__cast__(src).data.__dereference__(24))

So, basically do the following:

  1. init PNG decoder
  2. show a PNG image
  3. initialize a canvas: lv.canvas(lv.scr_act())

Merged!

Thank you.
