The problem is that I would not know how to do this. This LHS whitespace is buried within several layers of boxes. A lot of formatting would break if I tried to dissect formatting buried as deep as that. And it cannot be reassembled: for example, in a list involving AMSLaTeX displays, often an equation number is placed into a right-shifted hbox. When disassembling this stuff, the shift gets lost. > For now, this works well enough and is pretty fast: > pngtopnm trial004.png | pnmcrop - > trial004.ppm If it is just displayed equations you are bothered by, one suitable solution for the LHS whitespace would be to use the fleqn document-wide option when generating previews. Of course, this changes the veracity of the previews somewhat, but so would do other ways of cropping. I do remember vaguely that the implementation of this option might actually bypass display math mode, in which case automatic previews would not work, but a manual "preview" environment will always do the trick. > One more dumn question.

See the stuff that André quoted in a separate post. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum Email: [EMAIL PROTECTED]
