Mantra Custom Image Format (AOVs)

[nicholas_yue]

Hi,

 

    Using the IMG_Raw.C example, I am writing out a custom format/display-driver.

 

    However, when I started adding "Extra Image Planes" in the mantra ROP, I noticed that each plane triggers a new instance of my IMG_File derived class, I believe that's cause by the call to IMG_Format::create().

 

    Is the above to be expected and one should handle that in the ::create() method to only create one instance ? If not, what would be the correct approach ? Is there example code which handles multiple planes ?

 

    For my use case, I want perform the display-driver initialization once for all the planes and iterate each plane's data to send to the display application.

 

Cheers

In your custom IMG_Format class, override isDeepRasterSupported() to return true. That should cause your format to be recognized by SOHO as a multi-plane (AOV) image format.
