The menu of choices for grid-fitting and rounding any control point depends on whether you’re using a tool for the X or Y direction:
Rounding menus for the X and Y directions.
Each menu offers the same six choices (shown below for the Y direction only):
Option |
What It Means |
|
Fit the control point to the grid without rounding it. |
|
Fit the control point to the nearest grid line (“round to grid”). |
|
Fit the control point halfway between two grid lines (“round to half-grid”). |
|
Fit the control point to the nearest grid line or halfway between two grid lines, whichever is closer (“round-to-double-grid”). You’re fitting the control point to the nearest grid line in an imaginary grid with twice as many grid lines. This option is the most flexible, giving the rasterizer more options for positioning the point. |
|
Fit the control point to the next lower grid line (“round down to grid”). |
|
Fit the control point to the next higher grid line (“round up to grid”). |
You’ll use the first four methods most often. The round-down-to-grid and round-up-to-grid methods are used only to increase or decrease the tendency of distances and weights to reduce to nothing.
The second and third rows repeat the rounding choices of the first row, but you’ll use them only for control points in italic glyphs. For details, see Chapter 8, “Controlling Diagonals and Italics.”
To help you keep track of your hinting, you may want every point to display the rounding method, if any, you’ve applied.
