The old gray seen in  has ... issues.  shrink factor 8:   shrink factor 9:   So, even when using shrink factor 8, which given the 4x4 pixel pattern used for pixels in grayf.mf seems like it should put 2x2 proof pixels on one display pixel, something goes wrong and we get rows of missing pixels, and when we use an unrelated shrink factor we get something much worse :-(  What gray font / xdvi flags should I use to get my metafont proofs to render correctly?

I'm working through Knuth's Metafont Book as preparation for learning Metapost and I'm running into some problems working through his "experiments".  I've installed the latest TeX Live 2013 distribution on my system but I'm having problems.  Here's the code (contained in file io.mf as recommended by Knuth):  mode_setup;  em#:=10pt#; cap#:=7pt#;  thin#:=1/3pt#; thick#:=5/6pt#;  o#:=1/5pt#; define_pixels(em,cap); define_blacker_pixels(thin,thick); define_corrected_pixels(o);  curve_sidebar=round 1/18em; beginchar("O", 0.8em#, cap#, 0); "The letter O";  penpos1(thick,10); penpos2(.1[thin,thick],90-10);  penpos3(thick,180+10); penpos4(thin,270-10);  x1l=w-x3l=curve_sidebar; x2=x4=.5w;  y1=.49h; y2l=-o; y3=.51h; y4l=h+o;  penstroke z1e{down}..z2e{right}             ..z3e{up}..z4e{left}..cycle;  penlabels(1,2,3,4); endchar;   Now, when running the mf command and loading this file, I get a window that is unfortunately empty.  Supposedly a large letter "O" should appear.  $ mf This is METAFONT, Version 2.718281 (TeX Live 2013) **io (io.mf The letter O [79]) *end Output written on io.2602gf (1 character, 1724 bytes). Transcript written on io.log.  $ gftodvi io.2602gf  gftodvi: fatal: tfm file `gray.tfm' not found.   Then, when trying to use the gftodvi command I get the above error.   Any ideas why my "window" that should display the letter "O" is blank/empty? How do I resolve the gray.tfm error? Are the two related?   Note: I'm using Ubuntu 14.04, but the TeXLive installation is NOT from the Ubuntu repository.  I used the installer from  and created a local "portable" installation.

In Fedora 22, in KDE (plasma) System Settings -> Font -> Fonts, the setting for "General" is "Sans Serif 10", for "Fixed width" is "Monospace 10", for "small" is "Sans Serif 8", for "Toolbar" is "Sans Serif 9", for "Menu" is "Sans Serif 10", and for "Window title" is "OxygenSans 10".  How can I figure out which font file is being used for the generic "Monospace" alias?  (I'm sure I can follow the same procedure to figure out Sans Serif.)  fc-list shows 30 files, but fc-list | grep -I monospace shows nothing.  ("Monospace" must be an alias, and isn't the name of an actual font.)  fc-match --all shows 30 files, but likewise, fc-match | grep -I monospace shows nothing.  ls -la ~/.config | grep font shows nothing.  (No ~/.config/fontconfig)  /etc/fonts/fonts.conf lists font directories, accepts deprecated aliases, and points to /etc/fonts/conf.d.  /etc/fonts/conf.d/60-latin.conf is an XML file with element alias, with child family ("monospace") and prefer families ("Bitstream Vera Sans Mono", "DejaVu Sans Mono", "Incolsolata", "Andale Mono", "Courier New", "Cumberland AMT", "Luxi Mono", "Nimbus Mono L", Nimbus Mono", and "Courier").  /etc/fonts/conf.d/61-oxygen-mono.conf has child family ("monospace") and prefer family ("Oxygen Mono").  /etc/fonts/conf.d/69-gnu-free-mono has child family ("monospace") and prefer family ("FreeMono").  /etc/fonts/conf.d/69-unifont.conf has child family ("monospace") and prefer family ("FreeMono").  Now, in this case, the only prefer family quoted above that is installed is "Oxygen Mono" (in OxygenMono-Regular.ttf), so the system must be using that font.  But, what if some of the other prefer families were installed?  Isn't there a simple command that lets you see what a generic system alias like "Monospace" is mapped to?  I only see fc-{cache, cat, list, match, pattern, query, scan, and validate} on my system, and the only two that looks like they might perform this (list, match) don't seem to have this feature.

I watched a video on youtube (I lost it) that shows rendering parts of the screen to combine them in a single image. I followed it to the point where I couldn't adjust the dimensions under the "set render border", but in the video he had dimensions and I have nothing.  I need it for 4K and 8K renders (without anti-aliasing), but my laptop can't handle it all at once and I don't have time for a 4 hour waiting so this feature will work perfectly.  I'm using version 2.76 so is it moved to another place or removed. Maybe a bug?

I'm wondering why my browser (Firefox) add blue tints on the right and brown tints on the left of a solid grey (#333333) font color as shown in the image below.    Could somebody explain to me why this happens?

I was reading  on this site, and this was a sample of a cursive font from that discussion:     I really like it, but immediately noticed that it could not have been written by a human, because of how perfectly similar all of the t's and d's looked.   I think that creating convincing "dynamic" typefaces would be an interesting challenge. I don't know of any particularly good applications for it, other than to help out those folks with terrible handwriting, who don't have artistic skill, or who have disabilities (hooray for speech recognition!).   There should be a set of several glyphs for each character, so that they may be randomly chosen when typeset.   In order to get letters to flow together (as they should when using a cursive style) it seems like there needs to be ways to specify "regions" where lines can be bent to accomodate different combinations.   When not dealing with cursive, it is a much simpler problem, but I still don't know of any systems which focus on facilitating the creation of "variable" print. It would be dead simple: an extended font file, and a RNG.    So what I want to know is, has anybody else ever been bothered by this issue, where no cursive font has ever looked convincing? Are there any typographical systems which do these things I describe?

As in , the code  \draw[step=0.5cm,color=gray] (-1,-1) grid (1,1);   gives me a nice finite 4x4 grid. But when I choose a different starting point, like  \draw[step=0.5cm,color=gray] (2,2) grid (4,4);   then the left and the bottom border of the grid disappears. What is the problem and how can I fix it so that I have all the borders? I know I can draw a rectangle there, but I assume there is some cleaner solution.

I this setup as shown in the screenshot. The image transparency plugs into the mix factor, the transparent and principled nodes plug into the mix shader inputs. I'm trying to figure out how to introduce translucency into the setup. Any help would be appreciated.

I have a document, where I want to use $\tau_{ff}$. If this is rendered it looks like a space is inserted between the two f's. $\tau_{rl}$ looks fine ...   Where does this additional space come from and how can I avoid it being inserted?  (Miktex 2.9 on windows, if this is relevant).

I was planning to do a 1920x1080 wallpaper from my favourite musician's cover. Everything was going good so far until I used correction brush which totally ruined my whole work. There are pixelated lines (how do I call these?!) everywhere! They're everywhere, it's very visible when zooming. Using Content-Aware Fill did nothing about it. I beg for help. Sorry if I did something wrong writing this post, i'm a beginner.

Is there a simple way to display a color bitmap in grayscale with just HTML/CSS?  It doesn't need to be IE-compatible (and I imagine it won't be) -- if it works in FF3 and/or Sf3, that's good enough for me.  I know I can do it with both SVG and Canvas, but that seems like a lot of work right now.    Is there a truly lazy person's way to do this?

How do you make an enumeration where the enumeration counter appears within a frame decorated with Metafun?  The idea is to have something similar to an example on pg. 144 of the Metafun manual:    Except that "Zapf (1)" would be a counter rather a manual label.  Here is the code that reproduces the example with the manual frame:  \startuseMPgraphic{FunnyFrame}   picture p ; numeric w, h, o ;   p := textext.rt(\MPstring{FunnyFrame}) ;   w := OverlayWidth ; h := OverlayHeight ; o := BodyFontSize ;   p := p shifted (2o,h-ypart center p) ; draw p ;   drawoptions (withpen pencircle scaled 1pt withcolor .625red) ;   draw (2o,h)--(0,h)--(0,0)--(w,0)--(w,h)--(xpart urcorner p,h) ;   draw boundingbox p ;   setbounds currentpicture to unitsquare xyscaled(w,h) ; \stopuseMPgraphic  \defineoverlay[FunnyFrame][\useMPgraphic{FunnyFrame}] \defineframedtext[FunnyText][frame=off,background=FunnyFrame] \def\StartFrame{\startFunnyText} \def\StopFrame {\stopFunnyText } \def\FrameTitle#1% {\setMPtext{FunnyFrame}{\hbox spread 1em{\hss\strut#1\hss}}} \setMPtext{FunnyFrame}{}  \starttext  \FrameTitle{Zapf (1)} \StartFrame Coming back to the use of typefaces in electronic publishing: many of the new typographers receive their knowledge and information about the rules of typography from books, from computer magazines or the instruction manuals which they get with the purchase of a PC or software. \StopFrame  \stoptext   I was able to make enough progress to add an answer to this problem, but I'm still unsure if it's the right way to go.

What could cause this? f12:    Viewport:    (the f12 has fewer samples, but even when the viewport is at lower samples it looks different..)  I know about color management, but that is at the defaults..    EDIT: oops.. I know 'log' is not a default, but that is because I was fiddling with it. The image above is rendered with 'default'    The material is quite simple, only a translucent shader. (for testing) I even tried appending everything into a new file to reset all the settings, but no difference.  EDIT2: Uploaded blend

Does anyone know how to bold calligraphic \mathscr fonts in a math environment? I can get a fancy calligraphic font if I use \mathscr, but \boldsymbol does not work, nor does \mathbf. There is a hack which uses poor man's bold, but I was wondering if there is an alternate way to do this "cleanly". I've also seen \bm used for \mathcal font, but that's not what I'm looking for unfortunately.  I'm using calligraphic fonts with the following packages:  \usepackage{amsmath} \usepackage{amsfonts} \usepackage{mathrsfs}

Browsing through a copy of Counterexamples in Analysis (Gelbaum  &amp; Olmsted), I'm quite enjoying the typeface used for 'script' letters (see links to examples below); visually it's somewhere between what I'd now call calligraphic and fraktur, and semantically it's used where now we'd use mathcal, mathfrak or mathbb.  I was therefore procrastinatiously looking for a LaTeX-usable font to include these characters, but couldn't seem to find any. I'm certain they're not unique to this text or publisher, so figured my lack of success was probably more to do with searching with the wrong keywords. If anyone has any ideas I'd be grateful.

I wanted to amplify the effect of specifying the font size. So I tried: {\tiny\tiny Super tiny text!} But that doesn't seem to work. I needed suggestions to achieve the same goal.

i've installed mac version from kyngchaos including all required packages ... ... and just noticed the following:  while windows version behaves like expected when trying to render an ordinary tif via "singleband pseudocolor" (see the image)   the same procedure on the current mac-release returns:   interesting detail: pressing "apply" in mac version doesnt change anything and if you press "OK" and re-open layer properties the "render type"-setting has  swiched back to "singleband grey".  even more interesting: "singleband grey" is faulty too: none of the options "color gradient", "min", "max", "contrast enhancement" does affect the way the tif is displayed,  neither do the "load min/max values" settings !  anyone any ideas?
