We have an application running on customized i.MX6 using DirectFB for displaying images.
We now have a requirement of converting to portrait mode, currently the LCD is in landscape mode.. So , we want the image to be displayed 90 degrees rotated.
DirectFB only supports 180 degree rotation, If i pass "layer-rotate=90" or "layer-rotate=270", it throws error: "UNIMPLEMENTED".
I tried the rotation example from IPU examples, but it was rotating one image.. Now suppose if I want to use this IPU code and add it into the DirectFB for frame buffer rotation of 90 degrees.
I find some ipu example, hope helpful for you
