file mode fixes, added shebang to rendertext example script 2011-12-08 00:25:42 +00:00			`#!./kpdfview`
added freetype text rendering (still buggy) this allows to render glyphs and also brings a simple engine for rendering UTF-8 strings onto the framebuffer. blitting to uneven offset is implemented here, too, but needs more work and is still buggy. In the end, this will allow for a simple GUI. 2011-12-01 00:35:53 +00:00			`require "rendertext"`
major overhaul of the code structure, more OO like 2011-12-07 23:45:39 +00:00			`require "graphics"`

moved blitting over to blitbuffer API the framebuffer "object" now has a "member" that exposes the blitbuffer API for the framebuffer pixmap. This allows to reuse blitting & Co for blitbuffer-to-blitbuffer operations 2011-12-02 00:31:13 +00:00			`face = freetype.newBuiltinFace("sans", 64)`
			`--face = freetype.newFace("test.ttf", 64)`

Added kerning for rendering text 2011-12-01 15:11:43 +00:00			`if face:hasKerning() then`

fixed bug in rectangle painting and added example 2011-12-02 00:43:55 +00:00			`fb.bb:paintRect(1,1,599,300,7);`
