8.34 Text Tool
8.34.1 Overview
The Text tool places rendered text as a new selection. Prior to clicking on the
image, the standard GTK font chooser will be displayed. The font that will be used for
rendering can be selected from this dialog.
8.34.2 Text Tool Options
Text Settings
Antialiasing Antialiasing will render the text with much smoother edges and curves.
This is achieved by slight blurring and merging of the edges. This option can
radically improve the visual appearance of the rendered typeface. Caution should
be exercised when using antialiasing on images that are not in RGB color space.
Border The Border option allows a transparent border to be placed around the ren-
dered text. Normally text is rendered with no space between the text and the
layer or selection edge. This option changes that. The number selected here
represents the number of pixels to surround the image with.
Use Dynamic Text This option will display theDynamic Text Dialog in stead of the stan-
dard GTK font selection dialog.
