ImGuiFonts

Cross-target font loading helpers (hand-written, never regenerated).

With Dear ImGui 1.92 dynamic fonts (RendererHasTextures backends), fonts can be added at any time and are rasterized on demand at any size, so sizePixels is usually left at 0 (the size then follows style.fontSizeBase and pushFontFloat).

var font = ImGuiFonts.addFontFromBytes(myTtfBytes);
ImGui.getIO().fontDefault = font;            // global default font
// or per window / per widget:
ImGui.pushFontFloat(font, 18);
...
ImGui.popFont();

Add a TTF/OTF font to the atlas from haxe.io.Bytes. Returns the ImFont handle (target-typed). sizePixels = 0 uses the dynamic default size.

With merge = true, the font is MERGED into the previously added font instead of creating a new one: use this to add fallback glyphs (e.g. Japanese/CJK coverage, icons) to a base font. Order matters: add the merge font right after its base font.

The TTF data is copied to native memory that stays alive for the whole app lifetime (the atlas does NOT own it, fontDataOwnedByAtlas=false, to avoid any cross-target allocator mismatch; native malloc memory is not garbage collected so no retention is needed).

Add ImGui's built-in default font (ProggyClean) to the atlas and return its handle. Useful to keep the pixel font around after switching io.fontDefault to a custom TTF.
