Screenshot for draw/frame

[Abhishek Deshpande]

Hi,

I am using below arrangement

GLES APP => ANGLE (built with Vulkan BackEnd) => In House Vulkan loader/driver => HW

How do I get a screenshot (bmp/jpg) of a particular GLES draw/frame ?

Can LunarG screenshot layer help here ?

Or is there some ANGLE specific extension/switch that I can use ?

Thanks in advance,

AD

You can use glReadPixels to read back the data from an OpenGL framebuffer and then save that data to an image yourself. Libraries like stb_image can do the image file compression.
