import-pixmaps

Arguments: directory output-file &key make-masks filenames

Converts a set of .bmp pixmap files into a new file of Lisp source code. This is useful for building the pixmaps into the single image file of a delivered application, without needing to distribute the .bmp files themselves.

directory is a pathname or path namestring that names a directory containing one or more .bmp files to convert. (When a namestring, the final slash is optional.)

output-file is a pathname or path namestring that names a lisp source code file that will be created and contain generated lisp source code that creates the pixmaps. If a file already exists at this path, then it is replaced, so take care not to inadvertently destroy a needed file.

If make-masks is true, then generate-mask will be called on each pixmap so that the generated code creates a mask for each pixmap. The transparent-pixel-value passed to generate-mask will be nil, so the masks will be based on the upper-left pixel of each pixmap.

If filenames is nil or unspecified, then all of the .bmp files in the specified directory will be included. Otherwise it should be a list of strings which are the pathname-names of a subset of the dirctory's .bmp files to include.

The name of each pixmap in the generated code will be a keyword symbol whose name is the pathname-name its .bmp file, converting any spaces in the filename to dashes. The generated code also calls cache-pixmap on each pixmap that it creates, so that each one can be found at run time by calling find-pixmap on its name.

A similar effect can be achieved by calling load-pixmap and then calling recreation-code on the returned pixmap, but import-pixmaps makes this process more convenient.
