      +
    • Stroke or Fill
      • +
        +
      • cairo_stroke walks path outline with pen
        • +
      • cairo_fill paints interior of path
        • +
      • both operations consume the path, resetting the current path to empty
        • +
      +
    • Clip

        • +
      +
    • Fills interior
      • +
    • Even/odd or winding fill rules
      • +
    +     + + + + + +
  • cairo_set_source_rgb sets a solid color source
    • +
  • Source color is used for any drawing operation (stroke, fill, or
    • +
  • others)
    • +     + + +
  • cairo_stroke/fill_preserve preserve the path
    • +
  • Could just walk the figure twice

      • +
        +
      • translate, scale != scale, translate
        • +
      +
    +     + + + + + +
  • Even/Odd counts edges, fills when odd
    • +
  • Winding counts up for clockwise edges, down for counterclockwise, fills when !zero
    • +     + + +
  • Cairo memory surfaces are images
    • +
  • cairo_show_surface paints one surface into another
    • +
  • Transformed through matrix
    • +
  • No projective transforms yet
    • +     + + + + + + + + + + + +
  • Nearest Neighbor
    • +     + + +
  • Apply one surface as pattern on another
    • +
  • Pattern transformed through source surface matrix
    • +
  • Patterns may repeat
    • +     + + + + + +
      +
    • Source surface holds matrix
      • +
    • Constructed with matrix operations
      • +
    • Some thought to changing this API
      • +
        +
      • Need to add projective transformations
        • +
      • May want procedural patterns
        • +
      +
    +     + + + + + +
      +
    • No primitive gradients in cairo
      • +
        +
      • Implemented as patterns
        • +
      • Bilinear interpolation smooths result
        • +
      +
    • Future API may include more
      • +
        +
      • Procedural patterns
        • +
      • Triangular patches
        • +
      +
    +     + + + + + + + + + + + +
      +
    • API is getting replaced
      • +
    • “Toy” API will be similar to current code
      • +
    • “Full” API will have
      • +
        +
      • OS dependent font selection
        • +
      • Use Glyph Ids instead of Unicode chars
        • +
      +
    • New implementation will provide device-independent fonts
      • +
    • Old API worked only on X
      • +
    +     + + +
      +
    • Simple font selection
      • +
        +
      • family, weight, slant
        • +
      • OS independent
        • +
      • No font listing support
        • +
      +
    • UTF-8 text drawing and extents functions
      • +
    • Still supports full font transformations
      • +
    + + + + + +
  • C has no exceptions
    • +
  • Checking each return is tedious
    • +
  • C programmers rarely bother
    • +
  • Lots of broken programs result
    • +     + + +
  • Cairo returns status
    • +
  • Status is “persistant”
    • +
  • cairo_status function returns error state
    • +
  • API “shuts down” when an error occurs
    • +
  • All cairo functions are benign (and well defined) after any error.
