I'm creating a PDF document consisting of text only, where all the text is the same point size and font family but each character could potentially be a different color. Everything seems to work fine, but the default space between the lines is slightly greater than I consider ideal. Is there a way to control this?
According to the PDF specification, the distance between the baseline of two lines is called the leading. In iText, the default leading is 1.5 times the size of the font. For instance: the default font size is 12 pt, hence the default leading is 18.
You can change the leading of a
Paragraph by using a constructor that accepts a
You can also change the leading using one of the methods that sets the leading. For instance:
The first parameter is the fixed leading: if you want a leading of 15 no matter which font size is used, you can choose fixed = 15 and multiplied = 0.
The second parameter is a factor: for instance if you want the leading to be twice the font size, you can choose fixed = 0 and multiplied = 2. In this case, the leading for a paragraph with font size 12 will be 24, for a font size 10, it will be 20, and son on.
You can also combine fixed and multiplied leading.
