- When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them.
- Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide.
Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render"
phases of your own application. All rendering informatioe are stored into command-lists that you will retrieve after calling ImGui::Render().
phases of your own application. All rendering information are stored into command-lists that you will retrieve after calling ImGui::Render().
- Refer to the bindings and demo applications in the examples/ folder for instruction on how to setup your code.
- If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder.

Q: How can I display an image? What is ImTextureID, how does it works?
A: Short explanation:
- Please read Wiki entry for examples: https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples
- You may use functions such as ImGui::Image(), ImGui::ImageButton() or lower-level ImDrawList::AddImage() to emit draw calls that will use your own textures.
- Actual textures are identified in a way that is up to the user/engine. Those identifiers are stored and passed as ImTextureID (void*) value.
- Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason).
@ -638,7 +639,7 @@ CODE
- In the examples/ bindings, for each graphics API binding we decided on a type that is likely to be a good representation for specifying
an image from the end-user perspective. This is what the _examples_ rendering functions are using:
OpenGL: ImTextureID = GLuint (see ImGui_ImplGlfwGL3_RenderDrawData() function in imgui_impl_glfw_gl3.cpp)
OpenGL: ImTextureID = GLuint (see ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp)
DirectX9: ImTextureID = LPDIRECT3DTEXTURE9 (see ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp)
DirectX11: ImTextureID = ID3D11ShaderResourceView* (see ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp)
DirectX12: ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE (see ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp)
@ -669,26 +670,9 @@ CODE
This is by design and is actually a good thing, because it means your code has full control over your data types and how you display them.
If you want to display an image file (e.g. PNG file) into the screen, please refer to documentation and tutorials for the graphics API you are using.
Here's a simplified OpenGL example using stb_image.h:
Refer to the Wiki to find simplified examples for loading textures with OpenGL, DirectX9 and DirectX11:
// Use stb_image.h to load a PNG from disk and turn it into raw RGBA pixel data:
#define STB_IMAGE_IMPLEMENTATION
#include <stb_image.h>
[...]
int my_image_width, my_image_height;
unsigned char* my_image_data = stbi_load("my_image.png", &my_image_width, &my_image_height, NULL, 4);
// Turn the RGBA pixel data into an OpenGL texture:
GLuint my_opengl_texture;
glGenTextures(1, &my_opengl_texture);
glBindTexture(GL_TEXTURE_2D, my_opengl_texture);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glPixelStorei(GL_UNPACK_ROW_LENGTH, 0);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, image_width, image_height, 0, GL_RGBA, GL_UNSIGNED_BYTE, image_data);
// Now that we have an OpenGL texture, assuming our imgui rendering function (imgui_impl_xxx.cpp file) takes GLuint as ImTextureID, we can display it:
ImGui::Image((void*)(intptr_t)my_opengl_texture, ImVec2(my_image_width, my_image_height));
https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples
C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTextureID / void*, and vice-versa.
Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTextureID / void*.
