Please note that windows application needs explicit enabling of dpi awareness. I think there's something with rust's winit crate itself, because if I change the scale factor in OS settings, all the desktop elements are scaled, but the imgui stays the same. 80 Branch: docking Back-ends: imgui_impl_opengl3. Dragging canvas will add a render offset between ImGui content and the Modifies GUI.

This repo will remain intact, but archived, if you're too stubborn to use Vulkan. Unfortunately this method seems only to return the DIPFactor of the primary monitor. Three signatures are provided: HelloImGui::Run(RunnerParams &): full signature, the most customizable version. Outside of your specific use (appending new columns while table a showing): Dear ImGui uses 16-bit indexing by default, so high-density ImPlot widgets like ImPlot::PlotHeatmap() may produce too many vertices into ImDrawList, which causes an assertion failure and will result in data truncation and/or visual glitches. Note that I want the scaling I have implemented since it saves performance, I just want to turn off image scaling from ImGui side. Until they fix the problem, it is essential to remember to select "scale with screen space". Compiler, OS: Windows 11 + MSVC.

Namespace:ImGui Assembly:ImGui. Net + FNA (C#) Operating System: Windows. I've used DPI awareness with many other opengl applications successfully and that worked fine for properly scaling the Windows window itself, Scaling/Zooming #6074. isWindowsFont - if this is true, then the fileName will be appended to the Windows Fonts path, so it loads a Windows font. Reference⚓︎. 8 as the imgui_wgpu crate was still on 0. public struct Rect : This library is poorly documented at the moment and expects the user to be acquainted with C/C++. )Call ImGui::EndFrame after the last ImGui::End in your update function, if you update more than once before rendering. . 7 at the time. But the value is only being inherited from an immediate parent (not the whole window set up to the root). Option 1: Enable 32-bit indices by uncommenting #define For good reason (at least to ease avoiding resources leak) the ImGui_ImplDX11_CreateFontsTexture(); is a static procedure in imgui_impl_dx11. Call ImGui functions (ImGui::Begin(), ImGui::Button(), etc. Hello @ebachard,. Therefore, it is HIGHLY recommended that you EITHER:. cpp Compiler: Apple Clang Operating System: \\ here put in a call to user code the scales the fonts and UI based on the contents of mode - the following is just an example of code that changes the font to among a few pre-determined ones The initial idea was to use the ImGui::Image function to display the image, use the second parameter of the ImGui::Image function to control the size of the image, then use the ImGui::SetCursorPos() function and the ImGui::GetCursorPos() function to control the center of the image, and then ImGui::GetCursorPos() function to control the center You signed in with another tab or window. The docs in the demo says: I did try the ScaleAllSizes but it doesn't work correctly. The MediaPlayer component to display: Scale Mode: Aspect ratio fitting mode to use: Color: The color to multiply the video by. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use Long story short: The ImGUI window looks perfect on 1080p, but, obviously it looks tiny on resolutions such as 4K. using UnityEngine; using System. For example, I enabled per monitor DPI awareness and played with different DPI values, but it didn't scale imgui. My goal is to have an application that correctly DPI I have decided to include a few better color themes in the default packaging, perhaps as soon as next release (1. * remove stale code * compile API docs for the ImGuiStyle_ScaleAllSizes function from the imgui_dart library, for the Dart programming language. But perhaps I just overcomplicate things. However, we do use ImFontAtlas::TexGlyphPadding to facilitate a hack we have that adds an outline to the glyphs in the font texture. SDL2, GLFW3, and Glutin basically don't seem to have proper support for reading the frame buffer scale on X11, Wayland or Win32. ; 20+ Back-ends: ImGui. But, it`s ok as below. Icons⚓︎.

Recent 1. But moreover, if I'm right, if you actually insert a call to ImGui::SetWindowFontScale() in the child window of a window that already set the current window scaling, it'll actually multiply the two Due to Dear ImGui issue ocornut/imgui#5301, the font scaling on HiDPI setup (only on macOS) is not correct and results in blurry text. Image Each window can be polled for its DPI scale factor and they are correctly resized if moved to a window with a different scale factor or the user changes the monitor scale factor while the application is running. dll Syntax [Serializable] public struct Rect : IFormattable. You switched accounts on another tab or window. It demonstrates all the widgets, together with an example code on how to use them. For element types we use the same names as in ImGui itself. Solved I can pass an image, however, it doesn't seem to want to scale correctly to the viewport which I find most frustrating (below is an image for reference). * check DisplayFramebufferScale * start making a shim * automatic detection of scale factor on macos * make nix build succeed. Thank you. Initial scale: Result when increasing window size: (Due to extreme scaling, image pixels are visible) Result when decreasing window size: You should refer to those also to learn how to use the imgui library. Skia. The black rectangle represents a canvas border. public class ExampleClass : MonoBehaviour { private Vector2 scale = new Vector2(1, 1); private Vector2 pivotPoint; Version/Branch of Dear ImGui: Version: 1. Regards. 50). And that is what ImFontConfig::Density is for. It is fast, portable, renderer agnostic, and self-contained (no external dependencies).
