Dear all,
We use i.MX6DL-SABRE board with LinuxBSP(L3.14.28).
We made a sample code by referring to the Image Processing Unit V3 (IPUV3) Library User's Guide Rev.1.8 document.
We have some questions.
(Q1) For Combine
When X coordinate of Overlay is not a multiple of 8, the Overlay image is displayed in the place unlike an appointed position.
We understand that we can put overlay image in any place.
Is there the method to appoint any position(other than the multiple of 8) of the X coordinate?
(Q2) For Resize
When output resolution is not a multiple of 8, an overlay screen becomes black and it is not resized.
We understand that we can resize overlay image with any size.
Is there the method that an overlay image is resized optionally(other than the multiple of 8)?
(Q3) For screen display
When white and a black image are displayed at high speed in turn, the line such as the white joint area (tearing) is displayed.
Please refer to JPG file.
- with_FBIOPAN_DISPLAY.JPG
- without_FBIOPAN_DISPLAY.JPG
Is there the method that these are displayed seamlessly?
<sample corde>
- combine.c
- resize1.c
- resize2.c
- display_sample_A.c
- display_sample_B.c
<Image Processing Unit V3 (IPUV3) Library User's Guide Rev.1.8>
Could you give me some advice?
Best Regards,
Yuuki

Hello,
IPU requires aligned address for buffer for efficiency. This
may restrict X,Y addressing for pixels. Therefore please use aligned
addresses in applications.
Have a great day,
Yuri
