v1.13

What's Changed

Added support for the new Dear ImGui (1.92+) font atlas and its managed textures. This allows blitting glyphs as they are used instead of pre-rendering all of them into a large texture. NetImgui automatically forward the font atlas glyphs to the NetImgui Server with the desired DPI without any library user intervention.

Take a look at SampleTexture for more insights into using Dear ImGui's managed textures.

Version 1.13

(2026/01/05)

• API Changes
  • Added support of new ImTextureRef parameter to NetImgui::SetBackground(...)
  • NetImgui::eTexFormat enum entries shuffled
  • 'FontCreation callback' parameter in ConnectToApp(...) and ConnectFromApp(...) now ignored in Dear ImGui 1.92+
    • No need to regenerate texture atlas on DPI change anymore, making the callback pointless
    • Callback is left as a parameter for programs using Dear ImGui versions from before 1.92
    • If you did implement the callback, the code can be safely removed (on version 1.92+)
  • Disabled Custom Texture format
    • Allows transmitting data for user managed custom texture format but has not been made functional with updated texture system yet
• Backend change
  • Upgraded to Dear ImGui 1.92.5
  • Added support for new Dear ImGui 1.92+ font atlas
    • Font texture atlas contains needed glyphs only, doesn't pre-render all glyphs at each font point
      • This means much a smaller texture
    • Improved handling of monitor DPI
      • Transparent to library users
  • Added support for Dear ImGui managed textures
    • Automatic hookup into textures creations/update/destruction
    • Partial texture region update support
• Samples
  • Reworked 'Sample Textures' to demonstrate...
    • Creating, updating and using Dear ImGui managed textures
    • NetImgui automatically forwarding all of the managed textures operations to the NetImgui Server
    • The ability of still using your own textures objects
      • These need to be manually send to the NetImgui Server
  • Removed Sample DPI
    • Uneeded now that DPI is automatically handle without user needing to implement anything
  • Removed Sample DualUI
    • Can no longuer re-use same remote Imgui draw data to re-use for local display so remove it
• Misc
  • Updated Sharpmake version to 0.92
    • Added Visual Studio 2026 support
    • Used by Server and Samples solutions generation (not needed by library users of NetImgui's client code)
  • NetImgui Server application now remember previous window placement on launch
