The GIMP Generated Brush File Format Version 1 (.vbr)
|
|
-----------------------------------------------------
|
|
|
|
Updated August 24, 2006.
|
|
|
|
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
|
|
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 ASCII, 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, except the
|
|
number of spikes (for shaped brushes), which is an integer.
|
|
|
|
Non-shaped brushes:
|
|
|
|
Line 1: Must always contain the magic string "GIMP-VBR".
|
|
|
|
Line 2: Version number, always "1.0".
|
|
|
|
Line 3: The name of the brush. This is a UTF-8 string, with a maximum
|
|
length of 255 bytes.
|
|
|
|
Line 4: The brush spacing.
|
|
|
|
Line 5: The brush radius, in pixels.
|
|
|
|
Line 6: The brush hardness.
|
|
|
|
Line 7: The brush aspect ratio.
|
|
|
|
Line 8: The brush angle.

|
|

|
