gdkpixbuf.pixbuf_module_pattern

Module for [PixbufModulePattern] class

Types 1

The signature prefix for a module.

The signature of a module is a set of prefixes. Prefixes are encoded as pairs of ordinary strings, where the second string, called the mask, if not NULL, must be of the same length as the first one and may contain ' ', '!', 'x', 'z', and 'n' to indicate bytes that must be matched, not matched, "don't-care"-bytes, zeros and non-zeros, respectively.

Each prefix has an associated integer that describes the relevance of the prefix, with 0 meaning a mismatch and 100 a "perfect match".

Starting with gdk-pixbuf 2.8, the first byte of the mask may be '*', indicating an unanchored pattern that matches not only at the beginning, but also in the middle. Versions prior to 2.8 will interpret the '*' like an 'x'.

The signature of a module is stored as an array of GdkPixbufModulePatterns. The array is terminated by a pattern where the prefix is NULL.

GdkPixbufModulePattern *signature[] = {
 { "abcdx", " !x z", 100 },
 { "bla", NULL,  90 },
 { NULL, NULL, 0 }
};

In the example above, the signature matches e.g. "auud\0" with relevance 100, and "blau" with relevance 90.
