When searching for the word find in the PDF file in this Link before Ghostscript optimization the results will give pages number 4,7 and 13 but after the optimization it gives only pages 4 and 13 ignoring page number 7, the script im using for the optimization :
D:/gswin64c -sDEVICE=pdfwrite -dMaxSubsetPct=100 -dAutoRotatePages=/None -dMaxInlineImageSize=0 -dPDFSETTINGS=/ebook -dColorImageResolution=96 -dDetectDuplicateImages=true -dColorImageDownsampleThreshold=1.1 -dDOPDFMARKS -dUseTrimBox -sOutputFile="D:/temp/search_text.pdf" -dNOPAUSE -dNOGC -dBATCH -dNumRenderingThreads=8 -c 50000000 setvmthreshold -f "D:/temp/iphone_user_guide.pdf"
I've tried to add several fonts related parameters to the script such as -dEmbedAllFonts=true and pointing to fonts path also I've tried to play with the parameters by eliminating some but with no result
what could be the cause of this problem?
Ghostscript doesn't do 'optimization'. See my answer here:
GhostScript issues with a CropBox
for some details on what it does do.
Wihtout seeing your file I cannot tell you for certain what the difference is, but most likely the missing text has been drawn as images instead of text for some reason.
By the way, a lot of the options you are sending have absolutely no effect (eg NumRenderingThreads, for a device which doesn't do rendering). You should NOT select -dNOGC, that's a really bad idea, -dDOPDFMARKS is already set for the pdfwrite device.

I'm using the GNU texinfo package to generate both PDF and .info files from a .texi file.
I'm trying to update an old .texi file (not changed since 2001) and generate the same PDF output. I've resolved a number of issues, but there are a couple outstanding. In the old PDF, the title was in Helvetica and body text is Liberation Serif. In the new PDF, both are Computer Modern.
I've read everything that I can find about fonts, but I'm not able to change the fonts. Nothing that I do seems to work. Everything I have tried generates errors.
In my .texi file, before any \setfont directives, I have \def\fontprefix{uh} which, if I read the pdftex.map file correctly, should select the NimbusSanL font set (e.g. uhvr8a.pfb). I get the following errors:
mktexnam: Could not map source abbreviation for uhss10.
kpathsea: Running mktexmf uhss10
! I can't find file uhss10'.
<*> ...ljfour; mag:=1; ; nonstopmode; input uhss10`
Does anyone have a example .texi file which sets the font family to use? Or an explanation of what I'm doing wrong?
I have been trying to compile my latex code in overleaf.com, but it keeps giving the errors as follows, and it does not point in which line of the code the error is located in:
It seems like a font issue there and here is the raw log of the error:
{/usr/local/texlive/2021/texmf-dist/fonts/enc/dvips/ly1/texnansi.enc}
! error: (type 1): cannot open file for reading 'ugmm8a.pfb'
! ==> Fatal error occurred, no output PDF file produced!
I need to solve this error to get my output document.
The urw-garamond fonts works just fine with texlive2021, you just need the ugmr8a.pfb from https://www.ctan.org/tex-archive/fonts/urw/garamond
https://www.overleaf.com/read/cmvfrqrkrnrq
(... however it might give better results not to use such a legacy font if you're already using lualatex, overleaf has many good fonts installed https://www.overleaf.com/learn/latex/Questions/Which_OTF_or_TTF_fonts_are_supported_via_fontspec%3F)
I have found the solution to this problem by myself.
Turns out the solution was just to change the Compiler (TeX Live) version of the overleaf.com project from 2021 to 2016 (since the 'ugmm8a.pfb' font got depreciated in the later version).
Hence I had to press the Menu option in the Top Left of my project, and then change the "TeX Live version" from 2021 to 2016 as shown in the screenshot below:
And after this one change when I recompiled, my document was successfully outputted without any errors.

I'm using the nativescript-google-maps-utils plugin in a NativeScript JavaScript project to access GoogleMapsUtils functions (GMSGeometryDistance, GMSGeometryInterpolate, and GMSGeometryHeading) so that I can traverse a polyline. The Android equivalents work fine on Android devices, and the iOS functions listed work on an iOS simulator, but on an iOS device I get the exception,
ReferenceError: Metadata for "GoogleMaps.GMSGeometryDistance" found but symbol not available at runtime.
I've been chasing this for the better part of a day and still don't have any leads; I'd welcome any insight.
[edit]
It's worth mentioning I've done the usual removal of the platforms, hooks, and node-modules folders and rebuilt, with no change in the error.
Here's the first line of code that triggers the error:
let lineDistance = GMSGeometryDistance(latlngs[i], latlngs[i + 1]);
[edit 2]
Still chasing this... I gather from this issue that I need to create a file with a list of exported symbols, and this issue kind of suggests how that could be done, but I'm not understanding how that applies to this situation.
That is, the question at hand now is how can I determine the symbols from the iOS GoogleMapsUtils static library? This is becoming more of an iOS and Xcode question that NativeScript or JavaScript.
[edit 3]
Sigh... I did get this working using the answer I provided below, but now that same approach is no longer working. No idea why :-(
[edit 4]
I re-reviewed the links I referenced above and included the STRIPFLAGS option and now the code works properly. I revised the answer to include this, and to edit build.xcconfig rather than the project file.
After another day's investigation I was able to get this working. Here's what it took.
Navigate to /platforms/iOS/Pods/GoogleMaps/Maps/Frameworks/GoogleMaps.framework/
Run nm --defined-only GoogleMaps | grep " T " | cut -f 3 -d' ' | egrep -v '^$|GoogleMaps'
Notice the names of the symbols. In my case each one I needed was the function name prefixed with an underscore
Create the file exportedSymbols.txt in /app/App_Resources/iOS
Add the symbols to the file. In my case the contents is:
_GMSGeometryDistance
_GMSGeometryHeading
_GMSGeometryInterpolate
Edit the file app/App_Resources/iOS/build.xcconfig and add these two lines
STRIPFLAGS=$(inherited) -s {PROJECT_DIR}/../../app/App_Resources/iOS/exportedSymbols.txt
EXPORTED_SYMBOLS_FILE = ${PROJECT_DIR}/../../app/App_Resources/iOS/exportedSymbols.txt
So far this is working in my tests on both iOS simulators and devices.

While doing Selection Printing on Ricoh Afficio 2090 or any other drivers/printers get the following error printed on the sheets
ERROR: undefined
OFFENDING COMMAND: F4S47
Stack:
.
Kindly Review and suggest a turn around for the same as i am already stuck in this hell. I have tried to convert/extract in PS but all in vain. I am using gsview to Print and view these files.
This is the problem:
%%PageOrder: Special
A ps document with "Special" page order can NOT be re-ordered. You cannot do a selection or range with this file because it is broken for this use. You must reprocess the file using Distiller or ghostscript (ps2ps or ps2pdf) in order to print selected or re-ordered pages from the document.
You can avoid this by generating your postscript files with a real Postscript™ driver (one not created by Microsoft).
The GSView Documentation has more about this.
Previously:
This line ...
%%TargetDevice: (HP Color LaserJet 4500) (2014.200) 0
... tells us that the file was generated with HP printers as a target. So this really is not an EPS file. Because it's not Encapsulatable. To generate output on a printer the file has to execute the showpage operator, which is a no-no for EPS files.
So uncheck the EPS box (it's a big fat lie, anyway), and select (install) a Generic Postscript driver. If you need to send it to multiple makes of printer, the file needs to make as few assumptions about the printer as possible.
The first thing is that this is not a valid EPS file, as it has PJL attached at the front. Many PostScript printers will strip this off, but by no means all.
This probably is not the source of the problem.
There is no way to 'review' the problem as you have not supplied the complete PostScript program. Without that there is no way to tell what is actually wrong, the error message tells you that the interpreter encountered 'F4547' while trying to parse a token, and that this has not been defined as a routine.
Most likely the file is corrupt, either damaged in some way, or possibly it is a biinary file and has been transmitted by some process which does has done some kind of conversion (CR/LF is common). The offending command looks like its ASCIIHex encoded, so that may be a red herring.
If you want additional help, you are going to have to make the whole program available somewhere.
When using the MnSymbol package, pdflatex gives two font warnings:
LaTeX Font Warning: Encoding 'OMS' has changed to 'U' for symbol font
(Font) 'symbols' in the math version 'normal' on input line 120.
LaTeX Font Info: Overwriting symbol font 'symbols' in version 'normal'
(Font) OMS/cmsy/m/n --> U/MnSymbolF/m/n on input line 120.
It turns out that this is probably due to a clash with the AMSSymb package.
Since I need just a few symbols from the package: is there a way to load one symbol from a package, in stead of all?
Here's how I solved this:
Download the perl script "makefakeMnSymbol" from the comprehensive latex symbol document source:
http://mirror.ctan.org/info/symbols/comprehensive/source/makefakeMnSymbol
Next, at command line do chmod +x makefakeMnSymbol to make it executable. Then, run
./makefakeMnSymbol `kpsewhich MnSymbol.sty` > fakeMnSymbol.sty
Put fakeMnSymbol.sty in a texmf directory of choice (global or local), and run texhash
If you now put
\usepackage{fakeMnSymbol}
in your preamble, you can now use any MnSymbol, like \powerset by prefixing it like \MNSpowerset
Big thanks to Scott Pakin for this hack... and for his comprehensive symbol guide...
This hack has problems with symbols in subscripts/superscripts. A work-around is to use look at the fakeMnSymbol.sty source to find which font the symbol you want was loaded from, along with its number. Here's an example from one of my preambles where I override the built-in \boxminus with an MnSymbol:
\usepackage[]{fakeMnSymbol}
\DeclareSymbolFont{mnsymbolc}{U}{MnSymbolC}{m}{n}
\let\boxminus=\undefined
\DeclareMathSymbol{\boxminus}{2}{mnsymbolc}{112}
These warnings are nothing to worry about. In fact, in the next LaTeX release they'll disappear (see the original bug report). No ETA on that, however.
Moreover, is there any real chance this affects the typesetting of the document?
Nope.
is there any way to prevent this?
Can patch the LaTeX warning message code before loading the package, and then restore it again afterwards (this is what I've done in the past in my own packages), but as a user I'd just learn to ignore the warning.
The following might help. This is the code I had to add in order to get just the \bigominus symbol out of the MnSymbol package.
\DeclareFontFamily{U}{MnSymbolF}{}<br>
\DeclareSymbolFont{mnsymbols}{U}{MnSymbolF}{m}{n}<br>
\DeclareFontShape{U}{MnSymbolF}{m}{n}{<br>
<-6> MnSymbolF5<br>
<6-7> MnSymbolF6<br>
<7-8> MnSymbolF7<br>
<8-9> MnSymbolF8<br>
<9-10> MnSymbolF9<br>
<10-12> MnSymbolF10<br>
<12-> MnSymbolF12}{}<br>
\DeclareMathSymbol{\bigominus}{\mathop}{mnsymbols}{55}
