Next: Image Instantiator Formats, Previous: Image Specifiers, Up: Images [Contents][Index]
Conversion is applied to image instantiators at the time they are added
to an image specifier or at the time they are passed to
make-image-instance
.
This function sets the image-conversion-list for consoles of the given console-type. The image-conversion-list specifies how image instantiators that are strings should be interpreted. Each element of the list should be a list of two elements (a regular expression string and a vector) or a list of three elements (the preceding two plus an integer index into the vector). The string is converted to the vector associated with the first matching regular expression. If a vector index is specified, the string itself is substituted into that position in the vector.
Note: The conversion above is applied when the image instantiator is added to an image specifier, not when the specifier is actually instantiated. Therefore, changing the image-conversion-list only affects newly-added instantiators. Existing instantiators in glyphs and image specifiers will not be affected.
This function returns the image-conversion-list for consoles of the given console-type.
