    How to write to a GL_SRGB8_ALPHA8 texture in a compute shader?

    cybernoid

      I create a texture as:

       

      glTexStorage2D(GL_TEXTURE_2D, 1, GL_SRGB8_ALPHA8, 128, 128);

       

      Then tried to bind it to a compute shader as:

       

      glBindImageTexture

        (

        0,//unit

        texture,

        0,//level

        GL_FALSE,//layered for volume/array textures

        0, // layer

        GL_WRITE_ONLY,

        //GL_SRGB8_ALPHA8

        GL_RGBA8

        );

       

      And I get an invalid operation error but the compute shader seemingly writes the data?  I have tried a multitude of different formats for glBindImageTexture() but can't get past such errors.  What is the correct way to write to an GL_SRGB8_ALPHA8 texture in a compute shader?
