### Emacs-Lisp Functions

The file 3DLDF-1.1.5.1/CWEB/cnepspng.el contains definitions of two Emacs-Lisp functions that can be used to convert Encapsulated PostScript (EPS) files to structured PostScript (PS) and Portable Network Graphics (PNG) files.

 convert-eps filename do-not-delete-files Emacs-Lisp function
 Converts an EPS image file to the PS and PNG formats. If called interactively, convert-eps prompts for the filename, including the extension, of an EPS image file. It follows the procedure described above in Converting EPS Files, to create filename.ps and filename.png. If do-not-delete-files is nil, the .tex, .dvi, and .log files will be deleted. This is the case when convert-eps is called interactively with no prefix argument. If convert-eps is called interactively with a prefix argument, or non-interactively with a non-nil do-not-delete-files argument, these files will not be deleted.

 convert-eps-loop arg start end Emacs-Lisp function
 Converts a set of EPS image files to the PS and PNG formats. The files must all have the same filename, and the extensions must form a range of positive integers. For example, convert-eps-loop can be used to convert the files 3DLDFmp.1, 3DLDFmp.2, and 3DLDFmp.3 to 3DLDFmp.1.ps, 3DLDFmp.2.ps, and 3DLDFmp.3.ps on the one hand, and 3DLDFmp.1.png, 3DLDFmp.2.png, 3DLDFmp.3.png on the other. If convert-eps-loop is called interactively, it prompts for filename with no extension and the starting and ending numbers of the range. For all i \in \INT and start \le i \le end, convert-eps-loop checks whether a file named filename.i exists. If it does, it calls convert-eps, passing filename.i as the latter's filename argument. do-not-delete-files is also passed to convert-eps. If it's nil, the .tex, .dvi, and .log files will be deleted. This is the case when convert-eps-loop is called interactively with no prefix argument. If convert-eps-loop is called interactively with a prefix argument, or non-interactively with a non-nil do-not-delete-files argument, these files will not be deleted.
