Imgui: image, texture

Created on 24 Mar 2016 · 4Comments · Source: ocornut/imgui

Hi,

Sorry for some beginner questions.
Can you provide any short examples for loading a image in IMGUI?

i.e. .... img = ... loadimage('.....');
texture = /////
tex_id = ...
ImGui::Image(tex_id,....)

What type is ImTextureID, is it possible to get from a gl::Texture2dRef or ?

Thanks!

imgui isn't an image library. It is up to you to have the raw texture data
already uploaded to the GPU and ready to use for imgui to reference. You
should find another library or write your own code to get texture data into
memory and upload to DirectX or OpenGL.

The imgui.h header has type of ImTextureID, which is void *. It's simply a
type agnostic way of passing around texture references until it hits your
renderer to use. Type cast it to the type you expect for the rendering
backend that you have.
