2. Basics of Image Processing / 2.3 Layers

### 2.3.3 Text Layers

Text layers are useful - like the name lets suppose - for adding text to a picture.

Most image processing application are able to set text into a picture in some way. This has the disadvantage that the text is no longer editable afterwards.

Against that text layers stay editable. You can change the font or the size afterwards or fix a spelling error.

Text layers are very flexible. Not only one-line-text is possible but whole paragraphs. These paragraphs can - similar to a word processor - be left aligned, right aligned, centered, justified or forced justified. By using forced justified all lines of a paragraph - including the last one - are stretched in order to fill the line space.

A text layer can contain fonts in any number, the user is not limited to just one font.

PhotoLine offers another text option: path text. Path text is a text layer whose text isn’t displayed inside a rectangle but that is running along a vector path. Each subpath is used as separate line for path text (see chapter 6.2.9).

PhotoLine supports spell checking in text layers (see chapter 6.2.9). On Mac OS X the built-in spell checker is used. On Windows you will have to install Aspell. Aspell is Open Source can be downloaded from http://aspell.net/win32.
