The Transform panel Window > Panels > Transform allows you to apply simple transformations to the selected area or to the whole glyph layer when in the Glyph window, or to several selected cells when in the Font window.
- Before you apply a transformation to a whole layer or selected area, set the transformation origin using the button on the top-left.
- Click on the Apply button to perform transformations after you have entered values in the panel.
- Use the Reset button to change all fields back to their original values.
If you transform cells selected in the Font window, the transformation is applied not only to the elements but to the glyph metrics as well. If you have several layers/masters in the glyph the Transform panel affects them all.
The following transformations are available in the panel:
To mirror the layer or selection horizontally or vertically, use the buttons to mirror. The Scale transformation below can also be used to mirror.
The buttons can be used to align selected objects vertically or horizontally.
The offset transformation offers two modes: if the icon is visible, you can offset to the absolute position defined by the values you enter for X and Y co-ordinates; while if the button is visible, you can move by the designated distance based on the the values you enter for X and Y co-ordinates. You can switch between the modes by clicking on the icon that is currently visible. When applying the transformation, note that positive X and Y shift values move the layer or selection right and up, and negative values move them down and left.
The scale transformation lets you scale the layer or selection either proportionally and non-proportionally. Proportional scaling, the default, is represented by . Click on the icon to toggle non-proportional scaling, represented by . Values for scaling can be added in either percentage (displayed as %) or absolute units (displayed as u). Clicking on the currently selected method opens a dropdown menu where you can choose the option you prefer.
Note that the scale transformation can also be used to mirror/flip the layer or selection by using negative values. If you choose proportional scaling and enter 80% as the scaling factor, the selection will be scaled down to 80%. However, if you enter -80%, not only will the selection be scaled down, it will also be mirrored both vertically and horizontally.
To rotate the layer or your selection, enter the rotation angle in degrees. Positive values will rotate counter-clockwise and negative values rotate clockwise. You can also click on the corresponding icon to enter the rotation value.
To slant the layer or your selection, enter the slant angle in degrees. Positive values slant to the right, and negative values slant to the left. You can also click on the corresp icon to enter the slant value.
