![]() ![]() The first looks for points at the extrema that is, the uppermost point, lowest point, and leftmost and rightmost points of the glyph. More Points Than Appendix B of the PostScript Language Reference manual says that an interpreter is only required to support paths with 1500 points on them. In the Paths tab, both the Check Missing Extrema and More Points Than val tests can be valuable. Documentation on validation states : 'FontForge has two variants of Add Extrema, one which adds what it thinks are 'Good' extrema, and one which will add all. I use curve points throughout in the light of the enormous number of glyphs involved, I dont want to continuously switch between different types of points, and most hieroglyphs are curved in most places anyway. Hello, FontForge reports a font I'm working on as having a lot of missing points at extrema, so I'm trying to find the right way out to fix this problem. pfm at least none of the options offered seem to match that. Check Missing Extrema Both PostScript and TrueType would like you to have points at the maxima and minima (the extrema) of a path. Two problems in particular: 1) Missing extrema. also forestalls endless headaches with missing extrema points down the road. I note that the Import function in FontForge does not seem to allow import of a. The first thing we have to do is import the scan into the FontForge drawing. We recommend that virtually all curves have nodes at their extreme points (the only exception would be for very small features, whose position is not important to the imaging of a glyph). But even so, almost all fonts will translate imperceptibly close to the original without the metrics.Ĭurious: I had no difficulty selecting a font from the page in Safari. To automatically insert nodes at the extreme points of curves (or extrema), choose the Contour > Nodes at Extremes command. Then go to the menu and choose File > Import > Metrics and open the. In FontLab, I first open the binary data (the. Yes, to perfectly translate a font to another format, your should have access to the metrics. pfm files, which does not ask for, are of any use my understanding was that the. For sfd fonts it will also notice: Any open contours (more an issue in sfd files than in released fonts) Adjacent points too far apart in a glyph Unknown glyph referenced in GSUB/GPOS/MATH For PostScript fonts it will also notice: More points in a glyph than allowed by PostScript. So the site is pretty obviously geared towards Windows users. I then tried sending various types of Mac fonts and it returns an error message every time of Please select a file to upload before submitting. ![]() Now, if I do 'Find problems', the offending points are brought to my attention, and happily there is a 'Fix. I tried the site you linked to and it does work very well for Windows Type 1 PostScript of TrueType fonts. I use curve points throughout in the light of the enormous number of glyphs involved, I dont want to continuously switch between different types of points, and most hieroglyphs are curved in most places anyway. So I couldn't tell you why FontForge was generating so many errors. ![]()
