Potential rotated bitmap code update needed for compatibility with 2.7.5

Right, think its understood, up to now the code was having to deal with the buggy behaviour noted at drawRotatedBitmap Draws from wrong center if degrees is one of the four cardinal directions

But as of SDK 2.7.5, the line

github.com/timboe/FactoryFarming

src/ui.c

main


      
              pd->graphics->setDrawMode(kDrawModeFillWhite);
              char text[16] = "";
              snprintf(text, 16, "x%u", (unsigned) m_buySellMultiplier[m_mode]);
              pd->graphics->drawText(text, 16, kUTF8Encoding, DEVICE_PIX_Y/2 + 3*TILE_PIX, tY());
              pd->graphics->setDrawMode(kDrawModeCopy);
            }
          
            pd->graphics->popContext();
          
            pd->graphics->pushContext(m_UIBitmapRight);
            pd->graphics->drawRotatedBitmap(m_UIBitmapRightRotated, 0, 0, 90.0f, 0.0f, 0.0f, 1.0f, 1.0f);  
            pd->graphics->popContext();
          
            //UIDirtyBottom(); // why?
          }
          
          void drawUITop(const char* _text, LCDBitmapDrawMode _mode) {
            m_UITopVisible = (_text != NULL);
            if (_text == NULL) {
              return;
            }

needs to change to

pd->graphics->drawRotatedBitmap(m_UIBitmapRightRotated, TILE_PIX, 0, 90.0f, 0.0f, 0.0f, 1.0f, 1.0f);

to apply a 16 pixel offset in x.

Checking other games too...
