When I have TikZ images or I include
.png graphics, I need to use PDFLaTeX instead of plain
vanilla LaTeX. (That is, I need to use PDFLaTeX all the time, rather than just when I want to produce the final PDF).
Sometimes I forget that my current document (or one
\included in it) contains one of these things. The compilation using latex doesn't work. The errors I get out when this happens don't seem to be meaningful: they don't just say
No such file
LaTeX can't work TikZ
or the like. Is there anyway I can make these kinds of errors more transparent?
I've often spent ages fiddling with insignificant other bits of code, because I haven't realised it's the image that is messing up the compilation.
beamer also sometimes messes up in LaTeX, but I normally spot that one.
