How to use DM365 for resizing and stitching ?

abins

Hi,

Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4

I want to resize four D1 images in YUV420 semiplanar format to CIF resolution and display it on a D1 resolution display in a 2x2 grid. I am using DMAI BufferGfx type buffers to hold the images.

The example DM365 resizer code provided can resize a YUV420SEMI image. However this code gives the resized image with linelength equal to the output width and hence I have to do an additional framecopy to copy the resized image to the proper position in 2x2 grid of the final buffer for display. Can the resizer be configured so that it can output the image to the final position without needing any additional framecopy?

Regards,

I don't know about the S/W implementation, but there is register related to this. Please check the code related to this register setting.

RZA_SDR_Y_OFT(RZA_SDR_Y_OFT)

Hello Sang-Yong,

Thanks for the suggestion. I think I need to modify the driver code for setting the RZA_SDR_Y_OFT register. The current driver code sets this register to the width itself for YUV420SEMIP format.
