Some pages on the wiki are generated by this program: http://wiki.freepascal.org/BGRABitmap#BGRABitmapTypes_unit_reference The idea is to add comments with a specific format: - on the line preceding a declaration - using { } brackets - starting with * for a main entry. Example: {* Specifies the shape of a predefined blur } - starting with ** for a sub-entry. Example, one enumeration: {** Gaussian-like, pixel importance decreases progressively } The sections titles are prefixed and suffixed by ===. Example: {=== Miscellaneous types ===}
