outline determines whether a shape adds or subtracts to the image (the absolute
values of the result is used in the image). Furthermore this means that the
library only supports curve types that are used for drawing glyphs; specifically
- this means that lines and quadratic Bézier curves are supported by cause this
+ this means that lines and quadratic Bézier curves are supported because this
is what is required to draw vectorised bitmap fonts and TrueType fonts, but also
cubic Bézier curves as this is required for OpenType fonts and circular arcs
as this is commonly used for corners when stroking the outline of a glyph.
- The create an image, first create a buffer using rtgrpblib_create_raster(3)
+ To create an image, first create a buffer using rtgrpblib_create_raster(3)
(if you already have one that is large enough, you can reinitialise it with
- rtgrpblib_reset_raster(3)), and than using the drawing functions
+ rtgrpblib_reset_raster(3)), and then use the drawing functions
(rtgrpblib_draw_linear_bezier(3), rtgrpblib_draw_quadratic_bezier(3),
rtgrpblib_draw_cubic_bezier(3), and rtgrpblib_draw_circular_arc(3)) to
draw the components of each shape's outline. When done, create an image
using the rtgrpblib_fill_shapes(3) function: you will receive a ink-level
map, where the value 0 means background, and 1 means foreground, and values
- between are colours between (no transfer function is applied).
