Simple Glyphs - Contours
You can perform several operations on contours while in Contour mode.
To select an external contour of a black area of a glyph click within the black area. To select an internal contour of a black area click within the internal white area.
To select more than one contour, press and hold down the Shift key while selecting contours. Another way is to click on the workspace where no contours are and, while holding down the left mouse button, drag a rectangle around all contours you want to select simultaneously.
Use the Ctrl-A shortcut or select Select All from the Edit menu to select all contours. Holding down the Shift key and clicking a contour already selected will remove that contour from the current selection.
Resize selected contours
When you select one or more contours, a box with "resizing handles" shows up around the selected contour(s). Click and drag one of those resizing handles to change the size of the selected contour(s). By default the selected contour(s) remain proportional to the original size, as you resize it. Press the Shift key while you drag one of the resizing handles located at the corners to resize freely.
To constrain a selection so it moves only horizontally or vertically, press Shift as you drag the selection. Press Alt to ignore the snap to grid and snap to guidelines features.
To copy selected contours to a new position, hold down the Ctrl key as you drag the selection. Hold the Alt key to ignore the snap to grid and snap to guidelines features. Hold down the Shift key to move only in vertical or horizontal direction. Any combination of these keys is allowed.
You can rotate by first selecting a contour (or more) and then select it again (don't double-click). The little rectangles on the corners will change into circles. These can be used to rotate the selected contour(s). The other four rectangles are used to skew the selection. To change the origin for the rotation you can move the little cross in the middle of your selection. To rotate by 15° steps, hold down the Shift key while rotating the selected contours. If Shift is held down on the skew operation, then it will skew by 1° steps.
As mentioned in the simple glyphs introduction, a contour is either made out of quadratic or cubic Bézier curves. When you perform tasks like adding contours, FontCreator will add such contours as either quadratic or cubic, based on the TrueType/OpenType Outline Format setting in the Font Export Settings dialog.
If you wish to convert existing quadratic contours to cubic or vice versa, then select the contours, right-click to open a context menu from where you can select Convert.
Here are some ways to add a contour:
To draw a rectangle, click the Rectangle toolbar icon on the Drawing toolbar. Then click within the Glyph Edit window to set the first corner of the rectangle. While keeping down the left mouse button, move to the opposite corner of the rectangle, and then release the left mouse button. If you want a perfect square, do keep the Shift key down while defining the rectangle.
To draw an ellipse, click the ellipse toolbar icon on the Drawing toolbar and follow the same procedure as described with the rectangle above. Use the Shift key to make a perfect circle. Since outlines are made out of Bézier curves, and such curves can't be used to make a 100% perfect circle, FontCreator will use 12 points which is good enough for most situations. If drawing a circle or ellipse larger than the em square (units per em as defined on the General tab on the Font Properties dialog) it will appear with 20 (quadratic) or 24 (cubic) nodes to provide even more precision.
To insert a new contour, select Contour from the Insert menu. Click with the left mouse button to add points. You can create a curve if you hold down the mouse button while moving it around. Creating points while holding down the Shift key generates straight lines (horizontal or vertical). After you have created your contour you press the Apply button.
If you add a rectangle, square, ellipse, circle or a new custom contour, FontCreator will decide the contour direction, unless it is overlapping another contour. You can always change the direction of a contour if needed.
There are several other ways to add outlines (contours) to a glyph:
•Using the Free Draw Contours tool.
•Drag and drop a glyph from the Samples toolbar into a Glyph Edit window.
•Copy contours from other glyphs, even from other fonts and paste them. (These operations carried out in their respective Font Overview or Glyph Edit windows)
•Import a stored vector or bitmap file of an image of a glyph into a Glyph Edit window using Import in the Tools menu.
•Paste a Clipboard image of a glyph into the Glyph Edit window. The Clipboard image could be created in another application which has graphics editing capabilities e.g. a cropping function. This operation is performed using the Paste option in the Edit menu.
This advanced feature will try to reduce the number of points that make up the contour(s).
Note: the optimize contour feature might slightly change the original outline, so do experiment with it to ensure it suits your needs. At all times you can make use of undo and redo, so it should be easy to compare the optimized contours with the original outline.
