    How can you do 2D alpha blending on SGX 350?

    Is the OpenVG Linux driver made ontop of OpenGL ES?

    I tried to use OpenGL 2.0 emulator to blit textures but it didn’t give me the excepted result.

    Here is a screenshot of the orginal, GL_LINEAR and GL_NEAREST:

    Here is the code for this: http://pastebin.com/m49d636e6

    I’m just wondering what I should use for 2D acceleration…

    Hi,

    Are you sure your viewport size is actually 800×480? In windowed environments you have to be careful to set the client area of the window instead of the outer size which includes title bar and borders.

    Regards,

    Georg
