I have a question which might be obvious, but I can’t find it in the FAQ or forums. I am using Tesseract OCR on Mac Mojave. I am a new user. Using the following command and seeing the following in the terminal:
tesseract /users/SamBell/Desktop/handwriting-test2.jpg out
Warning: Invalid Resolution 0 dpi. Using 70 instead.
Estimating resolution as 553
My question is - where is the output file saving to?
out.txt would be saved in the current directory. Execute pwd command in the Terminal to display the path to the directory.
I'm trying to visualize a code base without explicit doxygen comments, I run into what seems like an error when viewing the dot graphs in the html generated by doxygen Generated Boxes
I'm running doxygen under a cygwin bash with GraphViz installed. Any Ideas?
OK, figured it out...the blank boxes should have been a dead give away that the problem was with a missing font dependency. I installed a different version of GraphViz that had the font dependency resolved under mingw.
I know about services like Online Font Converter, but I am interested in offline solution, preferably over command line. Does anyone know a tool or workflow how to convert WOFF to OTF/TTF offline?
I wrote a simple tool for that:
https://github.com/hanikesn/woff2otf
Currently only tested with ttf files.
Here is the reference code for making WOFF files: http://people.mozilla.org/~jkew/woff/ I have a mirror: https://github.com/samboy/WOFF
To compile and install, make sure you have the zlib development libraries installed (e.g. in CentOS6 yum -y install zlib-devel as root), then
git clone https://github.com/samboy/WOFF
cd WOFF
make
Then, as root:
cp sfnt2woff /usr/local/bin
Once this is done, to make a webfont, enter the directory with the .ttf file, then run sfnt2woff
sfnt2woff Chortle2014f.ttf
This creates a Chortle2014f.woff webfont file. Replace “Chortle2014f.ttf” with the name of the actual webfont to convert.
The first link I provide has Windows and MacOS binaries for people who do not wish to install a compiler.
Here is the reference code for making WOFF2 files: https://github.com/google/woff2 Note that this code will not install in CentOS6, but compiles and installs just fine in CentOS7:
git clone --recursive https://github.com/google/woff2.git
cd woff2
make clean all
woff2 font generation is similar:
woff2_compress Chortle2014f.ttf
I didn't like the fact that the current best answer is a Python script, and there also appear to be cases of people saying it doesn't work. In addition, none of the current answers seem to make mention of compiling WOFF converters with the zopfli compression algorithm, which is superior to the standard zlib algorithm that other tools use. For these reasons I decided to go the "proper" (i.e. non-script) route and add my own answer in the process.
Note: the compilation process for both of the below utilities is very easy, and made even easier by simply copying and running the snippets of code I've provided below, but they do still require a working compiler. If you haven't compiled software from source before, you may need to setup a compiler environment first. If you're using Cygwin, you can follow the first part of my answer here to set up the MinGW-w64 cross-compiler.
WOFF CLI converter (with ZOPFLI compression)
First, compile and install sfnt2woff1 by pasting all of the following into a terminal and pressing Enter:
git clone https://github.com/bramstein/sfnt2woff-zopfli.git woff &&
cd woff &&
make &&
chmod 755 woff2sfnt-zopfli sfnt2woff-zopfli &&
mv woff2sfnt-zopfli sfnt2woff-zopfli /usr/local/bin &&
rm -rf ../woff
Once the tool has been compiled and installed, convert a TTF or OTF file to WOFF by running:
sfnt2woff-zopfli <inputfile>.ttf
You can also use the -n option to increase the number of iterations the program is run in, increasing compression at the cost of conversion time (the default number of iterations is 15).
To convert all files in the current directory to WOFF:
for i in *; \
do sfnt2woff-zopfli.exe "$i"; \
done
WOFF2 CLI converter (with Brotli compression)
First, compile and install Google's woff2 tools by pasting all of the following into a terminal and pressing Enter:
git clone --recursive https://github.com/google/woff2.git &&
cd woff2 &&
make clean all &&
mv woff2_compress woff2_decompress woff2_info /usr/local/bin &&
rm -rf ../woff2
Once the tool has been compiled and installed, convert a single TTF or OTF file to WOFF2 by running:
woff2_compress.exe <inputfile>.ttf
To convert all files in the current directory to WOFF2:
for i in *; \
do woff2_compress.exe "$i"; \
done
You can even convert a WOFF2 file back to TTF or OTF:
woff2_decompress.exe <inputfile>.woff2
1 Note that SFNT here refers to the SFNT table format that both TTF and OTF font formats are built around.
Ive been looking for this too but, sorry i couldn't find an offline one but i found this:
http://orionevent.comxa.com/woff2otf.html - no longer available
its really good
EDIT: Found a command line tool
https://superuser.com/questions/192146/converting-from-woffweb-open-font-format
I used the python script linked above by
barethon to write an online javascript converter of WOFF to OTF
I realise this thread has been inactive for some time now, but with the help of a few stackoverflow users, I was able to use the above mentioned python script [woff2otf.py by #hanikesn] to create a workflow allowing batch conversion of woff files.
If not for the original poster's use, then for others who come across this thread in search of the same thing, check out my thread for details on how to do this:
Modify Python Script to Batch Convert all "WOFF" Files in Directory
Even if you don't need to batch convert, onlinefontconverter.com produces unreliable results, and everythingfonts.com has a 0.4 MB limit on conversions unless you upgrade to a paid account, and both are needlessly time consuming compared to offline solutions.
Good luck!
EverythingFonts has an online tool that appears to work well.
If you wish to do it offline, following Erik Tjernlund's answer on Super User, you can downloaded the source and compile executables of woff2sfnt and sfnt2woff.
The latest version as of this writing was from 2009/09/09. Unfortunately I've discovered that it doesn't appear to work for all WOFF files, sometimes complaining of a bad signature and sometimes simply giving a broken OTF file.
On a Mac with Homebrew it's simpler than the other mentioned approaches.
.woff2 to .ttf
brew install woff2
woff2_decompress somefont.woff2
This will leave you with somefont.ttf in the same directory.
.woff to .ttf
Converting WOFF (not woff2) is a little trickier, woff2_decompress probably won't handle it. You would first want to convert the .woff file to .woff2, then use the woff2_decompress command to turn that into .ttf file.
There's a brew tap that can be used to install sfnt2woff, which can be used to convert your .woff to .woff2.
brew tap bramstein/webfonttools;
brew install sfnt2woff;
sfnt2woff somefont.woff;
woff2_decompress somefont.woff2
I want to create QR codes for a project I'm working on in applescript the resulting qr will be placed in the indesign document. I have found that there is a plugin for indesign but I suspect that requires user interaction.
So I've been search for how to generate the qr using a shell command. I've found things related to php and rails and even coldfusion but none of those will fit the bill on this. I need to generate them using shell command so image events or perl basically anything I can run from the command line that comes with the mac os
thanks for your help.
antotheer
I wonder if I could call a url using curl or somthing to get one ?
For doing something similar, we use libqrencode.
It's a c library for generating QR codes, but it comes with a command line utility (called qrencode) which lets you generate QR codes from a string, e.g.:
./qrencode -o /tmp/foo.png "This is the input string"
It supports most options you'd probably want (e.g. error correction level, image size, etc.).
We've used it in production for a year or two, with no problems.
I've only run it on linux systems, but there's no reason you shouldn't be able to compile it on Mac OS, assuming you have a compiler and build tools installed (and any libraries it depends on of course).
As Riccardo Cossu mentioned please use homebrew:
brew install qrencode
qrencode -o so.png "http://stackoverflow.com"
I would like to know how to extract a list of unique lines from a text file.
Preferably through Cygwin.
sort -u file > new_file
Your question is somewhat unclear. If you want to eliminate all duplicate lines from a text file you can do something like this:
cat file.txt | sort | uniq
Since the original question referenced Cygwin, which is Windows specific, I'll mention that Luis' answer works just as well using the GNU utilities for Win32 sort. I use the GNU ports off a USB key when I'm working on a machine that I don't want to install Cygwin on, or downloading and installing Cygwin seems like too heavy a solution for the problem I'm trying to solve.
