Hi, i'm working with the STM32F746 discovery board and i want to display bitmaps from sd card to the screen.

Using the example LTDC_PicturesFromSDCard i've managed to display 24 bit bitmaps on screen, however when the bitmap files are smaller than 80 x 80 pixels the images get display wrong. they then look tilted and under a angle of 30 degrees to the right (like italic letters)!
When i use the smaller bitmaps in the demo LTDC_PicturesFromSDCard they also are tilted the same.

who knows whats wrong here ?
