Import Vector Image
Import Image can be selected from the Tools menu when you have activated a Glyph Edit window or it can be selected from the context menu after right-clicking in the window. When you open a vector based image file, the file will be instantly imported.
In vector based image editing software you can use all kinds of objects to create your images. Such objects can be paths, lines, shapes, text, etc. That's not it, as you can also apply specific strokes to each of these objects. These strokes control thickness, how segments join, and the appearance of both ends of an open path. There are numerous other capabilities like fill objects, gradients, etc.
FontCreator can only extracts the bare paths, thus completely ignores the strokes, fills, etc. And since glyphs can only consist of closed contours, all open paths are automatically closed.
Here is a logo created with Adobe Illustrator. It contains four lines and a rectangle with two rounded corners and a gap at the lower right. All of these objects contain strokes to give them thickness.
When imported into FontCreator, the result is not as intended as the strokes are not imported, thus the thickness of the objects is stripped off. The lines are all discarded as contours with only two points are useless. The rectangle is imported but the gap is no longer there.
One easy step ensures our vector image can be safely imported into FontCreator. In Adobe Illustrator, select all objects, then from the main menu select Object -> Path -> Outline Stroke. The result is shown here:
When we import this version of the vector image the result is a perfect fit!
5 contours with 44 points is the final result.
Tip: You can also paste an image from the clipboard or drag and drop image(s) from explorer into the Font Overview and Glyph Edit windows.
Note: You can't import images into composite glyphs.
