We are working on STM32F429ZI controller board with STEmwin. Right now we are facing two issues.

1) By default display is portrait . We want to show images with Landscape mode. So used GUI_SetOrientation(GUI_SWAP_XY | GUI_MIRROR_Y); function and got landscape mode of a LCD. But now touch is misbehaving. We touch some where but Cursor is shown at some difference location. In case of portrait mode, touch works perfectly. How to get touch to work with changed Landscape display ?

2) Using GUI builder i made one .c file using PNG images. But when i try to compile it gives me an error : no definition for IMAGE_SetPNG.
I checked this link. Both the files are present but still there is no success. JPEG images works perfectly. How to resolve this issue ?

Okay i solved this problem by using TM_EMWIN_Rotate(TM_EMWIN_Rotate_270);


But issue 2 is still there. Any solution for it ??

Solved this issue by downloading PNG library mentioned in User manual.
