On the other hand some errors are, in fact, warnings and do not necessarily impair the glyph’s outline quality.FontLab Studio is thenext-generation professional font editor created for Windows. You can switch off any of the FontAudit tests by switching off their check boxes in the FontAudit panel’s options:Īs you can see, FontAudit testing can detect errors that are invisible without you having to do a tough, lengthy analysis. Line or curve is short enough to be deleted. not exactly horizontal or vertical)Ĭontour visually appears to be closed but is defined as open This refers to the direction of the straight segment is close to vertical or horizontal but is not parallel to one of the axes (i.e. Handles are present but have zero in their length field Intersecting handles make the curve segment to loop which is almost always unwanted Сusp is a special version of the loop, where the curve loops as a single sharp point

This refers to what looks like a smooth connection but is labeled as a sharp connection This error can cause problems with rasterization of the glyphĪ straight segment and curve or two curves are connected very close to a smooth connection, but not precisely. There are “invisible” extreme points on curves. It is better to break such a curve into two curves with a node at the inflection point Collinear refers to a single straight line with one or more extra nodes in the middleĭetects curves that have inflections - points where the curve changes direction without a node present. Two sequential straight segments are collinear therefore the first straight segment can be removed. Although if the curve is truly perfectly flat this will not cause rendering issues, but it makes the font file bigger for no reason, and makes it easier to cause the line to be accidentally curvy again In fonts with PostScript outlines this error can cause problems with rasterizationĬurves that can be replaced with a straight segment without loss of quality (a “curve” that is really a straight line). Unnecessary straight segment on a contour, leaving a zero-length “ClosePath” between the last point and the first point in the path. Lines or curves that have no length (example: two nodes on top of each other)Ĭontours consisting of one vector having only two nodes on its endsĪny contour which is not closed including empty contours.

The shape of the contour may benefit from reconfiguration of the curve Use Genius connections to improve smoothnessĬontrol points of this curve are unbalanced. Node is located very close to the point of a smooth curvature connection. Tests that are new in FontLab VI are listed first. Here is a short description of each test and the error that it detects. Glyph > Fix FontAudit Problems will do Fix All for all selected tests, applicable to currently selected glyphs or to the active glyph in the Glyph window. Use the Fix feature carefully and be prepared to Undo an automatic fix. Sometimes correcting one error causes others, so on occasion when you press the Fix (or Fix All) button you will see even more errors. This dialog has two buttons, Fix and Fix All, which you can use to try to automatically fix an error ( Fix button) or all errors in the glyph ( Fix All).

For a full description, click on the mark to see the FontAudit error details. Hover the mouse pointer over the mark to see the short name of the error. Or it marks cells in the Font window with red marks in the right top corners: If FontAudit finds what it thinks is an error, it shows a red arrow error pointer in the editing field of the Glyph window. You can check glyphs selected in the Font window as well: select several cells and choose Glyph > FontAudit Glyphs. FontAudit will be visible in the Editor and Elements modes of the Glyph window. To turn on FontAudit, go to the menu bar, and select View > Show > FontAudit. Making a Font From Color Vector GraphicsįontAudit is a set of algorithms that analyzes a glyph’s outline to easily spot odd points and suspicious curves or technical errors that may cause the glyph to not render as well on screen or in print.Detecting Element References or Composites.
