The VBR format is used for "generated" brushes, that is, brushes
|
|
|
|
|
specified by a set of numerical parameters rather than a bitmap or
|
|
|
|
|
pixmap. This format dates back to at least 1998, although it
|
|
|
|
|
has been tweaked several times. The most recent tweak, in August
|
2006-09-24 06:12:30 +08:00
|
|
|
2004, added support for variable shapes. Prior to this, the
|
|
|
|
|
version number used was always 1.0. The version number used for
|
|
|
|
|
shaped brushes is 1.5.

VBR files are plain text tiles, consisting of a set of fields
|
|
|
|
|
separated by line breaks. The number of lines is variable, 10 if the
|
|
|
|
|
brush is "shaped", 8 otherwise. All numerical fields are in float
|
|
|
|
|
format, with a dot as decimal separator, except the number of spikes
|
|
|
|
|
(for shaped brushes), which is an integer.
