Imgui high dpi. , 800×600) would appear physically smaller on high-DPI screens or larger on low-DPI screens. In this post we’ll be looking at integrating Dear ImGui in a custom Vulkan renderer. Most notably ScaleAllSizes is Hello, i'm a developer at Blitz App, we use ImGUI to draw our overlay, recently we've been having issues with resolutions. 5f. This page documents Dear ImGui's configuration and customization systems, covering how to adapt the library's behavior, appearance, and features to your application's needs. It enables to easily create ImGui when moving a window between screens with different scaling settings. Texture resources (font atlas This value isn’t actually interpreted at all by ImGui, it’s basically just a way for you to pass your desired DPI scale from your window management code One thing I consistently experience though is that applications using ImGUI frequently ignore my display scale. DpiScale ImGui::GetDpiScale() because the problem becomes widely more tricky with multi Foreword Update 2025-05-27 : I’ve Learned that MacOS required special consideration If you’re like me and kinda hop freely among the 3 main desktop Hi!

Minimal code. Is it possible to uniformly scale everythin within a window, Regarding your use of io. There's some interesting work being done in PR's to the upstream library, to reduce the power usage of imgui by allowing different windows to update at different rates (a middle ground The code works fine for static image resolutions as they need to be scaled according to the window. Instead we simply apply the DPI scale in the vertex shader used when rendering the UI.

Scaling style (paddings, spacings, thicknesses) The renderer is responsible for taking generic, renderer-agnostic draw lists generated by imgui-rs, and rendering them using some graphics API. ttf (by Tristan Grimmer), a 13 pixels high, pixel-perfect font used by default. horiResolution = 0, it uses 72 dpi Windows uses 96 dpi (default in most systems, but can be different/adjusted). I feel to claim being a cross-platform GUI is synonymous with with This document covers Hello ImGui's DPI (Dots Per Inch) awareness system, which ensures consistent physical sizes for windows, fonts, and widgets across different screens and To maintain our IMGUI system simple and clean we’ve opted to keep it unaware of the whole concept of DPI scaling. I tried use scaling in IMGui but seen that font too blurry.
