1hp2xx-3.4.4 2 3This is mainly a bugfix release to correct some problems found in 3.4.3. 4In addition, it provides a tentative framework for truetype font support 5and a few other minor enhancements. 6I would greatly appreciate receiving bug reports, patches or even sample 7HPGL files.

Depending on the font, this should 30 produce better-looking text than the default stick font at the expense 31 of higher CPU and memory consumption. Support for non-ASCII characters 32 is lacking, and the rendering is at the mercy of the still imperfect 33 polygon rasterizer. 34- Support for the rectangle mode of the PE statement (Eugene Doudine) 35- NR is now recognized as an image terminator in multi-plot files. 36- DXF output provides optional translation of pen number and/or width 37 into DXF group 62 line attributes (Georg Viehoever). 38- The error handler now tries to report the offending HPGL command sequence, 39 not just its position in the input stream 40- New option for mapping pen 0 commands to another pen, to avoid changing 41 the background color in raster output modes. 42 43Bug fixes: 44 45- penwidth was erroneously set to the default 0.1 mm after drawing a label 46- xfig and rgip output did not yet handle the changed pencolor and width 47 settings 48- polygons sometimes had the wrong sections filled in for some of the 49 scanlines 50- forcing penwidth via the -p commandline option no longer worked for 51 the conventional values between 1 and 9 52- PJL parser now handles input lines of up to 256 characters 53- polygon sides could escape clipping in some circumstances 54- WG support was broken in 3.4.3 (coordinate error resulted in odd shapes) 55- simplified HPGL output would write very small numbers in exponential 56 notation, which is not allowed by any HPGL standard. 57- DT handling was both incorrect and incomplete 58- pdf and eps modes were using much too large miter limits 59- exporting to raster modes could fail in some circumstances due to 60 wrong linewidth corrections being applied in the raster buffer. 61- arcs drawn with 'deviation distance' chord tolerance parameter were 62 drawn as acute angles or even crashed hp2xx 63- PNG export of color graphics was broken in 3.4.3 64- SP command in PE mode did not update the internal pencount, potentially 65 leading to use of a reduced color palette in the raster modes. 66- Using -h,-? or even -help no longer generates an error message before the 67 usage text is shown. 68
