/*
Bindings for [[ Jimmy Lefevre's Text Shape ; https://github.com/JimmyLefevre/kb ]] Unicode text segmentation and OpenType shaping.
Example:
// Basic
OdinAllocator := context.allocator
FontData, _ := os.read_entire_file("myfonts.ttf", OdinAllocator)
Context := kbts.CreateShapeContext(kbts.AllocatorFromOdinAllocator(&OdinAllocator))
kbts.ShapePushFontFromMemory(Context, FontData, 0)
kbts.ShapeBegin(Context, .DONT_KNOW, .DONT_KNOW)
kbts.ShapeUtf8(Context, "Let's shape something!", .CODEPOINT_INDEX)
kbts.ShapeEnd(Context)
CursorX, CursorY: c.int = 0, 0
for Run in kbts.ShapeRun(Context) {
Run := Run
for Glyph in kbts.GlyphIteratorNext(&Run.Glyphs) {
GlyphX := CursorX + Glyph.OffsetX
GlyphY := CursorY + Glyph.OffsetY
DisplayGlyph(Glyph.Id, GlyphX, GlyphY)
CursorX += Glyph.AdvanceX
CursorY += Glyph.AdvanceY
}
}
Example:
// Font collections
OdinAllocator := context.allocator
FontData, _ := os.read_entire_file("myfonts.ttf", OdinAllocator)
Font := kbts.FontFromMemory(FontData, 0, kbts.AllocatorFromOdinAllocator(&OdinAllocator))
_ = kbts.ShapePushFont(Context, &Font)
FontCount := kbts.FontCount(FontData)
for FontIndex in 1..<FontCount {
kbts.ShapePushFontFromMemory(Context, FontData, FontIndex)
}
Example:
kbts.ShapeBegin(Context, .DONT_KNOW, .DONT_KNOW)
kbts.ShapePushFeature(Context, .kern, 0)
kbts.ShapeUtf8(Context, "Without kerning", .CODEPOINT_INDEX)
_ = kbts.ShapePopFeature(Context, .kern)
kbts.ShapeUtf8(Context, "With kerning", .CODEPOINT_INDEX)
kbts.ShapeEnd(Context)
