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 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. + +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. + + +Shaped brushes: + +Line 1: Must always contain the magic string "GIMP-VBR". + +Line 2: Version number, always "1.5". + +Line 3: The name of the brush. This is a UTF-8 string, with a maximum + length of 255 bytes. + +Line 4: A string giving the shape of the brush. Currently "circle", + "square", and "diamond" are supported. The possible shapes + are defined by the GimpBrushGeneratedShape enum in + core-enums.h. + +Line 5: The brush spacing. + +Line 6: The brush radius, in pixels. + +Line 7: The number of spikes for the shape. + +Line 8: The brush hardness. + +Line 9: The brush aspect ratio. + +Line 10: The brush angle. -- cgit v1.2.3
