[XeTeX] ifpdftex, ifxetex and dvipdfm

[Pablo Rodríguez]

Hi there,

thinking about helping to extend movie15 to dvipdfm (I cannot promise 
anything, because I must first learn how to do it ;-)), I have 
encountered an issue.

movie15 is written with two outputs in mind: pdftex and dvips. The main 
structure is based on ifpdf-conditionals. To improve dvipdfm support in 
movie15 (without having to rewrite the package from scratch), it would 
be necessary a conditional to separate different outputs for dvips and 
dvipdfm.

I guess ifxetex is not the package, because xdv2pdf cannot process 
dvipdfm specials (AFAIK), but even then dvipdfm(x) are still there and 
xetex doesn't use them.

I'm new to this, but the issue here is that both dvips and dvipdfm come 
  after TeX processes the source file, so an ifdvipdfm cannot be used 
here. At least, as far as I know.

Is there a way to write a conditional that avoids the use of options in 
the package? Or how can I get different outputs for dvips and dvipdfm?

Thanks for your help,


Pablo
