Member Function Documentation
| void drawImage | ( | gfxLcd * | glcd, |
| int | xOffset, | ||
| int | yOffset | ||
| ) |
Draw bitmap to the LCD.
- Note:
- There is no image buffer in this class instead the image is read from the fs every time it's drawn. This should be still fast enough as mBeds flash is still faster than the LCD.
- Warning:
- This class doesn't understand padding so images must be resized to size where paddings isn't needed. Also because of one bit BMP format the iamge width should be divisiable by 8.
- Parameters:
-
*glcd Reference to gfxLcd object. xOffset Start drawing from point x. yOffset Start drawing from point y.
