What I am looking for when I try it is if the pdf files I can get is of high quality. Unfortunaltely that never is the case. So am I just stupid or is there a way to get really high quality pdf from LYX? Yes. Make sure the default font is not a bitmap font. Unfortunately, the default font is a bitmap font. You must change it. So, go "Document->Settings->Fonts" and choose something else instead of "standard". There is "Latin Modern" if you like the look of the standard font on paper, but want nice pdf. Or select something else like Times Roman, Palatino, . . . Helge -- I've been using Century Schoolbook, which shows up as one of the choices with LyX as it comes with Mandriva and Ubuntu. Is Century Schoolbook a vector font? I found Latin Modern too light and stringy. I don't know. Last time I tested, only the "Default" resulted in ugly PDFs. That was a long time ago though. The test is simple enough - write with the font you want to test, and view the resulting PDF in adobe acrobat. In acrobat, zoom in as much as possible. If the huge glyphs on your screen looks ok, then it is a good vector font. If there are "staircase effects" on anything that should be round or slanted, then you have a bitmap font. You should use acrobat for this test. Some other PDF viewers handle bitmap fonts better, and don't get such visible problems. To avoid making this change for every document, save it as the new default. Main purpose is to read on the computer so both images and text should be suitable for that. That took care of the text, now for the images. What exactly is the problem with your images? If you draw something, make vector graphics rather than bitmaps, if possible. If you need screenshots, use png. Never jpeg, jpeg is only for photos. I didn't know .png is a vector graphic. No, png is not a vector format. But a PC/mac screenshot is never in vector format anyway. The point was - when you need bitmaps, use good ones. Jpeg will mess up any hard edges (such as a screenshot with text and window edges in it.) Jpeg is fine for photos - that is what jpeg was designed for. (Joint Photographic Expert Group.) Unfortunately, too many people abuse jpeg for screenshots and line drawing, mistakenly thinking it is some kind of generig graphics format. It is definitely not! I've been converting graphics to PDF before using them -- PDF *is* a vector format after all, and it seems to scale well. However, it would be soo much easier to use .png. Thanks for the tip. If your material is bitmap graphics, then png is a good choice. Note that bitmaps can be converted to PDF, but that does not make it vector graphics. This because PDF can embed bitmaps. (And so can postscript.) If your app can save as pdf, ps, eps or svg, then chances are it makes vector graphics. And then it makes sense to keep the graphics in vector form all the way to the printer or the reader's screen. The problem with bitmaps is that they has limited resolution. If the reader's screen (or the printer ot be used) has higher resolution, then the bitmap has to be upscaled. Upscaling is _never_ a perfect process. It tend to introduce staircase effects on slanted lines, or possibly blurriness in an attempt to cover up the staircase effects. There are always someone with high-end equipment that has a higher-resolution screen than you. And even the cheap printers has much higher resolution than the best screen around. You can fix this by making bitmaps with very high resolution, but then the files get enormous and cumbersome. Vector graphics have no such problems. They are not arrays of pixels, but a set of drawing commands. [Draw a green line from location (5,5) to location (1882,9644) and so on.] Such drawing commands work with any resolution, be it a 96 dpi screen, or a 1200 dpi photosetter. The output is as good as it gets on that output device, no matter what. And the files are considerably smaller than high-resolution bitmaps too. It is the same with fonts. A vector font consist of drawing instructions for each letter. (A "T" is a couple of lines with a specific thickness, and so on.) A bitmap font provides a bitmap. The bitmap is ok at some resolution, and insufficient at higher resolutions. Historically, the bitmap approach was considered easier. As far as the original poster, I've found that the output quality depends as much on the PDF reader as anything else. I've had docs that were beautiful on Acroread and ugly on xpdf, and others that were ugly on Acroread and beautiful on xpdf. I hate to admit it, but if my eBooks look good on Acroread, that satisfies 95% of my potential readers so I let it go that way. Most people use acrobat indeed. Acrobat does not handle bitmap fonts too well, especially not if you magnify. This

Let me try to defuse some objections from the discussion 1 1/2 years ago:
"LM are [...] not by default included in all LaTeX distributions, for
example not in MiKTeX."
1. This would indeed be a problem, but is this still true today?
2. The Debian LyX package could recommend the "lmodern" package.
The Windows-Installer could recommend loading at least the T1 encoded
LM fonts.
"LM are included in basic versions of TeXLive and MiKTeX, but the problem
is that we still have teTeX users where LM is not included."
A. I argue that teTeX users are by now a minority that can be expected to
change a setting that suits most users of up-to-date LaTeX
installations.
"there's no reason to force users to use a certain font and not the LaTeX
default one."
1. There is a reason:
* LyX does not use the default TeX font encoding (OT1) but
the T1 encoding (for sensible reasons).
* In this encoding, the TeX default fonts (CM) are only available as
bitmaps.
2. We do not force users to use a certain font but set a working
font-encoding/font combination as initial default.
My suggestion is *not* to change the meaning of [Default] but to set
[Latin Modern] in the standard *template*. This is easily reversed by
the user:
* Make a document
* use the menu Document->Settings->Fonts
* Set the Roman font, Sans serif font and Typewriter font to "Default".
* Use the button "Save as Document Defaults".
"Why do you think we should especially use LM and not TeXGyre or one of
the various other beautiful fonts?"
1. Principle of minimal change/surprise:
We'll let the pre-set font *look like* the default one.
2. As CM lookalike, LM works best with the various extensions/symbols
created for CM. Hence LM has the best available math support.
3. "If you want a font, select one and then it's up to you how the result
looks and you are aware of that selecting a different font leads to a
different output."
"LM and CM differs also in shapes, a good example is the German sharp s
"ß" character."
1. These changes are still minor in comparision to selecting a completely
different font, so they do not impede the compatibility with other
fonts designed to work with CM.
2. Opinions differ, but for me the Geman sharp s 'ß' (the es-zet) is an
example for the "Internationality" of the LM fonts. The LM ß is the
version recommended in German typesetting ("Sulzbacher Form"), while
the CM ß is a ligature of ſ (long s) and s.
"I don't think that they should be set as default. When you create a
new document, the corresponding latex file should ideally be
\documentclass{article}
\begin{document}
\end{document}
"
A. In this case, you would need to turn off hyperref anyway.
Just reset the fonts to [Default], too.
"you could choose to load your own font package in order to substitute
standard fonts with something else. So, if we load, without you knowing
it, the lmodern package, a clash could arise"
A. You will see [Latin Modern] in the font selection GUI. Just reset the
to [Default].
"lmodern is about 12 MB to download and we got complaints that I we even
check if this font is installed as this could lead to a package download,
but not everybody has a flatrate "
A. Without flatrate, you should not set up non-interactive package download.
"> This one's easy to argue against. First of all, LyX is a 24MB download

36 instead of 24 MB is 50% extra, and this only for a font.

A. LM is ~ 50 % of LyX, but less than 50 % of LyX + (LaTeX - LM).

My (admittedly quite trivial) point was that people should not assume a PDF file is in vector graphic format when---thanks to the enormous popularity of the file format---some application software will offer to save bitmaps as pdf, thus (perhaps) misleading the user into thinking they have produced a vector graphics when that's not the case.

Stefano Franchi schrieb: Only PDF and SVG are vector graphics. EPS is also a vector graphics format but many EPS images are only wrapped bitmap images. Isn't the same true for PDF? You can wrap bitmap files in it, I think Yes, it is the same but rather seldom used. So check that you have a real vector graphic, zoom into it. regards Uwe
Re: lyx and pdf fonts
I get great PDF output, that can be scaled to any size. The only thing I did was to set the encoding to OT1. If you don't use international characters, that should enable LaTeX to use vector fonts.

You can wrap bitmap files in it, I think (e.g. when scanner software offer a "Save as pdf" option). File format in itself is not necessarily an indication of bitmap vs. vector graphics. With the possible exception of SVG, perhaps (which I use but am pretty ignorant about)?

PNG is as well as JPG or GIF a bitmap graphic. the difference is inly the compression method. Only PDF and SVG are vector graphics. EPS is also a vector graphics format but many EPS images are only wrapped bitmap images. You can check of an image is a vector graphics by zooming into the image. When it becomes pixeled, it is a bitmap. regards Uwe

Steve Litt schrieb: I didn't know .png is a vector graphic. It isn't. As Helge said, it's pretty useful if you need some pixel graphics with relatively large areas of similar colors like screenshots. It is relatively small and has lossless compression. For Photos, jpeg is better but has lossy compression, tends to introduce artefacts. SteveT

Helge -- I've been using Century Schoolbook, which shows up as one of the choices with LyX as it comes with Mandriva and Ubuntu. Is Century Schoolbook a vector font? I found Latin Modern too light and stringy. > > To avoid making this change for every document, save it as the new default. > > > Main purpose is to read on the computer so both images and text should be > > suitable for that. > > That took care of the text, now for the images.

I've been converting graphics to PDF before using them -- PDF *is* a vector format after all, and it seems to scale well. However, it would be soo much easier to use .png. Thanks for the tip. As far as the original poster, I've found that the output quality depends as much on the PDF reader as anything else. I've had docs that were beautiful on Acroread and ugly on xpdf, and others that were ugly on Acroread and beautiful on xpdf. I hate to admit it, but if my eBooks look good on Acroread, that satisfies 95% of my potential readers so I let it go that way.

See http://wiki.lyx.org/FAQ/PDF#toc5 Main purpose is to read on the computer so both images and text should be suitable for that. I gues it means that I need ttf or otf fonts in the pdf? Yes, you need vector fonts. The above link describes how to do that. Btw. the LyX documentation files (except of the Intro manual) you find in the Help menu also use vector fonts, when they look OK for you, your documents will look OK too. I think I asked this 5-6 years ago but it seems nothing has changed :( S back to Microsoft Word again :( Wow, you're giving up before you've got a reply to you email. regards Uwe

Sorry, but what do you mean by high quality? As far as I can see, my documents are perfect. I can zoom to whatever level and quality is perfect. I use eps graphics, and it is highest possible quality as well. Could it be your PDF reader the problem? Luca

So am I just stupid or is there a way to get really high quality pdf from LYX? Yes. Make sure the default font is not a bitmap font. Unfortunately, the default font is a bitmap font. You must change it. So, go "Document->Settings->Fonts" and choose something else instead of "standard". There is "Latin Modern" if you like the look of the standard font on paper, but want nice pdf. Or select something else like Times Roman, Palatino, . . . To avoid making this change for every document, save it as the new default. Main purpose is to read on the computer so both images and text should be suitable for that. That took care of the text, now for the images. What exactly is the problem with your images? If you draw something, make vector graphics rather than bitmaps, if possible. If you need screenshots, use png. Never jpeg, jpeg is only for photos. I gues it means that I need ttf or otf fonts in the pdf? I think I asked this 5-6 years ago but it seems nothing has changed :( Nothing much need to change. Have been making quality PDFs for more than 5-6 years. All you need is to know a few things, such as changing from the default font. Most software has a few things you need to know, and you can find it out on this mailing list if you want to. S back to Microsoft Word again :( Whatever you like. You'll be harder pressed making quality PDFs with word though. Helge Hafting

To get really high quality PDF from LaTeX, you need minimal study about LaTeX and vector fonts, microtype and images/pictures. LyX is not guilty of PDF quality as it is only editor using LaTeX to produce results. Your lack of knowledge is guilty in this case. If you would like to kindy ask for help on this list I am sure lot of people would help you with that, and you would get documents much better that from Word. So... please stick with Word and never return. Thank You! -- Manveru jabber: manv...@manveru.pl gg: 1624001 http://www.manveru.pl
