[hlx] \image and ps2image

[Ralf H. <ra...@he...>]

Hello,

I had a problem when using

    hyperlatex -image

in conjunction with the default \htmldirectory{.}.

hyperlatex produces a file.makeimage with the command

    mv file.png .

Of course this results in an error since the file is already there and
cannot be moved to itself.

Yes, it would be possible to convince my Makefile to ignore such an
error, but I think I have another solution. See the modified files in
the attachment.

hyperlatex.sty:
    I have modified \endimage to produce a command suitable for the
    modified ps2image. So instead of

    ps2image -png ... file.ps > file.png
    mv file.png .

    it will produce

    ps2image ... file.ps htmldir/file.png

ps2image:
    This script recognises the target filetype from a parameter that ends
    in .png or .gif. The extension .ps is always assumed to be the input
    filename.
    Since the target filename includes the targed directory, an additional
    move of the file is unnecessary.

    It even seems ps2image is a bit shorter. ;-)


The only problem that remains is the following.
It is now possible to say

\begin{image}{dir/file} ... \end{image}

and the picture file.png (or file.gif) will be generated in the
subdirectory 'dir', but only if 'dir' already exists. There is no code
at the moment, that would generate such a missing directory.

Maybe I could think about putting some extension code into my rhxxname
package, but this will take some more spare time.

Best regards
Ralf
