inserting pdf in lyx document
hi, i have a PDF document containing diagrams generated from an application (rather than a document processor) and i want to include it in my lyx document. actually i want to add it as an appendix section. i'm tired of googling and my trivial solution is to print empty pages in the lyx document and just insert the paper copy of the PDF in the right place (void pages to preserve the numbering/TOC order). however, i lost the page header/footer styles for this section. i tried to convert the PDF to PS, then insert as an image but i failed so, how can i insert a PDF in lyx/latex document? thanx, mustafa -- Mustafa M.

Italics in bibtex record
I'm using pybliographic to manage bibliography. Some titles I have quote book titles, and those words should be italicised. Is there any way to italicise these words either manually, or to mark those words as a book title (in such a way that jurabib might be coaxed to put them in italics)? Thanks, Declan

numbered within sections (but I think with the section number included):

Graphics quality in PDF vs. PS, etc.
Hi, all, I'm currently producing documents using LyX, in which graphics are often XFig figures. I like the fact that LaTeX fonts can be embedded in such figures, and look great when the final document is produced*. However, if such a figure is relatively complicated (for example, a large color plot of experimental data in which there's lots of small detail), the final .pdf (using pdflatex) from LyX usually has quite a bit of detail lost in the figure (small details seem averaged out and therefore blurry), whereas a .dvi or postscript document usually seems to retain most of the detail of the original graphic. Is this because of a convoluted conversion path, where at some (maybe more than one) step, some graphics detail is lost? Is there a way to possibly fix this? Thanks, Curtis O. * The original .eps figures are often produced using Mathematica. I then run these through pstoedit and make final adjustments (often none) in XFig. But because (I think) these figures aren't *originally* produced in XFig, the start XFig with LaTeX fonts and 'special' flag setting makes no difference when looking at the figures in XFig. NEW documents have the special flag and LaTeX fonts enabled; pre-existing documents do not. Therefore I run the final figures through another Mathematica script which simply turns all the text to LaTeX fonts (just sets one of the flags in the text portions of the XFig file to 0 ). If anyone has a better (regex?) way to do this, I'd love to hear about it! Down with categorical imperative! [EMAIL PROTECTED] or [EMAIL PROTECTED]

Re: SVGs with alpha channel transparency
sam2p mentions that alpha channel and transparency supported only for Indexed images: only one color may be transparent http://www.inf.bme.hu/~pts/sam2p/ This effectively means that sam2p does *not* support real alpha channel, since indexed images such as GIF support a single special color for complete (100%) transparency, as opposed to various 'cellophane' colors as permitted when a full alpha channel implementation is provided.

Serious performance problem with LyX 1.4.1 on OS X
When I first installed LyX 1.4.0 on OS X I had such serious performance problems that even on my dual proc G5 with 1 gig of Ram I could trivially type faster than LyX could print out my characters. So when LyX 1.4.1 was released with a focus on performance I was very excited. Unfortunately LyX 1.4.1 is as slow for me as LyX 1.4.0 is. In fact even on simple documents containing little more than text (e.g. http://www.goland.org/webtemplate.lyx) just typing simple text is so slow that I can easily out type LyX. Please note that I made sure to delete LyX 1.4.0 and do a new install of LyX 1.4.1 and then confirm that my newly installed program is indeed LyX 1.4.1 If anyone has any suggestions or ideas I would love to hear them because I depend on LyX for a book I'm writing and as things now stand I'm in trouble.

I'd post a minimal example, but the graphics files I'm working w/ are on the order of 5MB. I may be able to make up something simpler in a few days. Best wishes, and thanks, Curtis O.
Re: SVGs with alpha channel transparency
sam2p mentions that "alpha channel and transparency supported only for Indexed images: only one color may be transparent" http://www.inf.bme.hu/~pts/sam2p/ This effectively means that sam2p does *not* support real alpha channel, since indexed images such as GIF support a single "special" color for complete (100%) transparency, as opposed to various 'cellophane' colors as permitted when a full alpha channel implementation is provided.

Uwe pointed out that a recent version of inkscape provides a transparent pdf output. Another pointer, borrowed from the TexLive mailing list: http://www.inf.bme.hu/~pts/sam2p/ I read there that "sam2p can create EPS and PDF images with transparency" Alas, sam2p starts from bitmaps, not from vector graphics... -- John Pye Department of Mechanical and Manufacturing Engineering University of New South Wales, Sydney, Australia http://pye.dyndns.org/
Serious performance problem with LyX 1.4.1 on OS X
When I first installed LyX 1.4.0 on OS X I had such serious performance problems that even on my dual proc G5 with 1 gig of Ram I could trivially type faster than LyX could print out my characters. So when LyX 1.4.1 was released with a focus on performance I was very excited. Unfortunately LyX 1.4.1 is as slow for me as LyX 1.4.0 is. In fact even on simple documents containing little more than text (e.g. http://www.goland.org/webtemplate.lyx) just typing simple text is so slow that I can easily out type LyX. Please note that I made sure to delete LyX 1.4.0 and do a new install of LyX 1.4.1 and then confirm that my newly installed program is indeed LyX 1.4.1 If anyone has any suggestions or ideas I would love to hear them because I depend on LyX for a book I'm writing and as things now stand I'm in trouble. Thanks, Yaron
