    Hello,

    I would like to do pixel interpolation on a given image with SGX540. I have Pandaboard Ubuntu or Android both setup with everything working regarding SGX540. Note that I don’t have any screen output on the device and I want to do pixel interpolation millions of times on a single image.
    My questions are:
    – what’s the best way to import a fixed image into PVR (without the need to render anything on screen as there is not screen output). Any resource I could leverage?
    – then, how can I do pixel interpolation on the image?

    Any help would be appreciated!

    Hi,

    what’s the best way to import a fixed image into PVR

    Do you mean you want to store a raw image your application has generated in a PVR texture container?

    then, how can I do pixel interpolation on the image?

    For any image convolution, I would recommend using OpenGL ES 2.0 GLSL ES fragment shaders on full screen quads.
