| Summary | 0000559: Defining the same font twice messes up font expansion | ||||
| Description | See the attached files. It defines (sample.lua) a font twice: local ok,f = define_font("texgyreheros-regular.otf",65782 * 12) local num = font.define(f) local ok,f = define_font("texgyreheros-regular.otf",65782 * 12) local num = font.define(f) When I use the second font, font expansion gets messed up. When I use the first font, everything looks fine. I have used some extreme settings to visualize the problem. And also, the hyphenation is in the wrong language, but thats just for the sake of simplicity. | ||||
| Steps To Reproduce | Unzip the attached zip file and run `luatex sample.tex`. You need texgyreheros-roman.otf somehwere in your TeX installation. The output looks strange. If you remove the first `font.define(f)` line in the sample.lua file (or change the font size or name to some other value) the output looks correct. | ||||

font expansion is partly redone, so this needs to be tested in 0.78+ |
|
|
It appears that the bug is gone now, but I am surprised that other choices for the paragraph line breaks have been made. Is that a side-effect of ex-glyph? (It could also be a different font version) |

in the latest lua/font there has been some kern fixes for disc nodes, so that could be a reason (as standard hz also messes with kerns which is debatable) the current mechanism avoids several (redundant) calculations from the old code as well no longer uses cloned fonts, so maybe there could be less rounding loss |
