void textPath(string utf8)Adds closed paths for text to the current path. The generated path if filled, achieves an effect similar to that of [cairo.context.Context.showText].
Text conversion and positioning is done similar to [cairo.context.Context.showText].
Like [cairo.context.Context.showText], After this call the current point is moved to the origin of where the next glyph would be placed in this same progression. That is, the current point will be at the origin of the final glyph offset by its advance values. This allows for chaining multiple calls to to [cairo.context.Context.textPath] without having to set current point in between.
designers call the "toy" text API. It is convenient for short demos and simple programs, but it is not expected to be adequate for serious text-using applications. See [cairo.context.Context.glyphPath] for the "real" text path API in cairo.
utf8 | a NUL-terminated string of text encoded in UTF-8, or null |
