Version 1.10

(2023/12/30)

• API Changes
  • ConnectToApp() and ConnectFromApp() functions now accept a callback to be used by the NetImgui Server when wanting to update the font to a specific DPI scale.
    • Can be left untouched, with null used by default.
    • Without a callback, we apply the text scaling to ImGuiIO.FontGlobalScale instead of requesting the generation of a new font with increased pixel size.
    • Using ImGuiIO.FontGlobalScale gives a blurier text result than recreating the font with the exact DPI needed.
    • See SampleFontDPI for more info.
  • SendDataTexture() now support a new texture format kTexFmtCustom.
    • It requires that the dataSize parameter is specified since we can't deduce it anymore (but not used for other formats)
    • It allows user to send a texture command with custom data that also needs to be added to NetImguiServer codebase.
    • This could be used for movie streaming, etc...
    • See SampleTexture for more info.
• Upgraded Dear ImGui support to 1.90
• Added monitor DPI support
  • The Server now scale the text up on a high resolution monitor, so it can still be read
  • The Server font atlas is regenerated with a higher pixel size to match the resolution
  • The Client connected will be asked to regenerate their font atlas if they provided a callback when connecting
    • When this callback is received, the client codebase should regenerate the font atlas using the provided scale
    • When no callback has been assigned, the client automatically relies on ImGuiIO.FontGlobalScale when drawing (blurier results)
    • See SampleFontDPI for more info.
• Added Clipboard support
  • Can now seamlessly use text clipboard between Client and Server!
  • Text copied on the Server PC is now sent over to the NetImgui Clients and can be pasted inside their Dear ImGui content
  • Text copied inside the Client's Dear ImGui content is now received by the Server PC and can be used on it
• Shared Client configs
  • When adding a Client configuration on the NetImgui Server application, the property Shared can now be specified
  • When enabled, it will save the config in a User Directory instead of the current Working Directory
  • This means that user can have NetImgui Server applications in various locations, but they can all still share the same Client Configs.
  • Note: Requires that the function HAL_GetUserSettingFolder() is implemented in the NetImgui Server codebase. It has been done for Windows.
• Various small changes and fixes
  • When the NetImgui Server config file netImgui.cfg is detected readonly, now tries to create a second one. This should help if user submit the default config file to perforce but still want to add new Clients.
  • Quickly typed text was dropping characters when received by Client
  • DirectX textures error when quickly recreating them

• Upgraded Dear ImGui support to 1.89.5
• Various small changes and fixes

Fixed a memory leak in the NetImguiServer application. (Client code remains unchanged).

Version 1.7.5

(2022/01/31)

• API Changes
  • None
• Bug fixes
  • NetImgui Server memory leak fix

Note: Please use release v1.7.5. (Contains a memory leak fix on the NetImguiServer application)

Description A few bug fixes, to resolve some out of sync issue when compression active.

Version 1.7.4

(2022/01/30)

• API Changes
  • Removed the bWait parameter from Shutdown()
    • Always wait for Shutdown completion before returning now
    • This prevents multithread data release issues
  • Added a NETIMGUI_API define prefix to functions exported in NetImgui_Api.h
    • Similar to IMGUI_API, allows library user to control dll import/export
    • Takes the same value as IMGUI_API by default
• Bug fixes
  • Compression feature causing some out of sync issue with NetImgui Server
  • 32bits index support crash

New

• Data compression to greatly reduce bandwidth.

  • Can reduce the bandwidth by 100x+ with low overhead !

• Visual Studio 2021 support.

• NetImgui Server OpenGL3 support

Version 1.7

(2022/01/10)

• API Changes
  • Added SetCompressionMode(...) / GetCompressionMode(), allow library user to manage the data compression feature
    • By default, Client relies on Server Setting
• Data Compressions Support
  • Drawing data generated by the Client can now be compressed before being sent to Server
    • Greatly reduce the bandwidth between Client/Server at a negligible cost on the Client
    • Using Delta Compression. The draw data usually vary little from previous frame. Sending only the changed bytes produce great results at low overhead
  • Highly dynamic UI content lower improvements
  • A new sample (SampleCompression) demonstrate the use of data compression and its metrics
    • At 30 Fps, data rate send from client goes from ~ 3400 KB/s to ~ 22 KB/s (~ 160x improvement !)
    • Since it depends on static content, moving around a Window reduce the benefits
• Other Changes
  • Added OpenGL3 support to NetImgui Server
    • Still DirectX11 by default
    • OpenGL3 support helps with the Server Application port to non Windows OS
    • To enable, set HAL_API_PLATFORM_GLFW_GL3 define to 1 and HAL_API_PLATFORM_WIN32_DX11 to 0
  • Added support for Visual Studio 2021
  • Support up to Dear ImGui 1.86 has been tested

• Mostly some bug fixes **

Version 1.6

(2021/08/09)

• API Changes
  • None
• Other Changes
  • Mostly some small bug fixes
  • Fixed issue with keyboard input
  • Fixed 16/32bits index handling (NetImgui Server app now handle both case without recompiling)

• Dear ImGui 1.83 support
• Mostly some bug fixes and reduction of CPU/GPU usage by the NetImgui Server

Release notes

(2021/05/30)

• API Changes
  • None
• Other Changes
  • Mostly some small bug fixes
  • Reduced NetImgui server CPU/GPU usage
  • Better handling of NetImgui server's window move between 4K and lower resolution monitors

Release of NetImgui v1.4

• Dear ImGui 1.81 support
• Auto interception of Dear ImGui ImGui::NewFrame() / ImGui::Render() (no longuer need to use NetImgui::NewFrame() / NetImgui::EndFrame())
• User can now specify their own custom background image and color in their Client window.
• Updated the Client background rendering on the Server, for better handling of alpha channel (makes text more readable)
• Some bug fixes

Release notes

(2021/03/13)

• API Changes
  • Added SetBackground(...) letting user configure the client window background appearance
    • The new sample SampleBackground demonstrate its usage.
  • Removed support of empty API functions when NETIMGUI_ENABLED is false
    • Keeps NetImgui client code clutter to minimum.
• New
  • Auto interception of Dear ImGui ImGui::NewFrame() / ImGui::Render()
    • Using Dear ImGui 1.81's Callbacks support, replacing theses Dear ImGui functions call with NetImgui::NewFrame() / NetImgui::EndFrame() can now be avoided
    • This means less changes to existing codebase wanting to use NetImgui, only requiring a single call to :
      • Startup
      • Shutdown
      • ConnectToApp or ConnectFromApp
    • However, calling directly NetImgui::NewFrame() / NetImgui::EndFrame() has the additional benefit of being able to skip drawing when not needed
