How to link Fred's Magick Script TextCleaner with XCode Project - xcode

Question

I decided to rephrase the question. Here is the problem:
I've managed to run textcleaner.exe within my c++ program by calling:
system("/usr/local/bin/textcleaner g -e normalize -f 25 -o 10 [path to infile] [path to outfile]");
But now I get the error:
/usr/local/bin/textcleaner: line 389: convert: command not found
/usr/local/bin/textcleaner: line 400: [: : integer expression expected
/usr/local/bin/textcleaner: line 403: convert: command not found
/usr/local/bin/textcleaner: line 417: [: : integer expression expected
/usr/local/bin/textcleaner: line 423: [: : integer expression expected
/usr/local/bin/textcleaner: line 429: convert: command not found
--- FILE /Users/~/Desktop/kimlik/kimlik1.bmp NOT READABLE OR HAS ZERO SIZE ---
So what is the problem here? I am giving a correct image with the right path, so I think instead of the last line, the problem lies with the convert command within textcleaner.exe. How can I call textcleaner.exe and convert.exe at the same time so that when running the textcleaner.exe, it knows what command convert is?

I wouldn't recommend calling an external script from a C++ application. You'll need to worry about paths, loading shell environments, and external error handling. Not really hard to do, but I feel unnecessary. I would argue that if your developing a C++ solution, than integrate with Magick++ directly. Try the following...
Ensure that you installed ImageMagick with Magick++ support. This is usually enabled by default.
Update Xcode's Build Settings to include Magick++ flags.
Run Magick++-config --cxxflags in your terminal. The return values should be copied under "Other C++ Flags" option.
Run Magick++-config --libs in your terminal. The return values should be copied under "Other Linker Flags" option.
Xcode project should now support Magick++ library.
Finally, evaluate the source of Fred's fantastic textcleaner script. You should be able to mimic his techniques directly in C++.
For example. The script may generate the following convert command.
convert \( $infile -colorspace gray -type grayscale -contrast-stretch 0 \) \
\( -clone 0 -colorspace gray -negate -lat ${filtersize}x${filtersize}+${offset}% -contrast-stretch 0 \) \
-compose copy_opacity -composite -fill "$bgcolor" -opaque none \
-sharpen 0x1 \ $outfile
Which can be implemented with something like...
#include <Magick++.h>
using namespace Magick;
int main(int argc, const char * argv[]) {
long
filtersize = 15,
offest = 5;
const char
* bgcolor = "white",
* infile = "wizard:",
* outfile = "output.png";
InitializeMagick(argv[0]);
Image alphaImage(infile);
alphaImage.colorSpaceType(GRAYColorspace);
alphaImage.type(GrayscaleType);
alphaImage.contrastStretch(0, QuantumRange);
Image betaImage(alphaImage);
betaImage.negate();
betaImage.adaptiveThreshold(filtersize, filtersize, offest);
betaImage.contrastStretch(0, QuantumRange);
alphaImage.composite(betaImage, 0, 0, CopyAlphaCompositeOp);
alphaImage.fillColor(Color(bgcolor));
alphaImage.opaque(Color("none"), Color(bgcolor));
alphaImage.sharpen();
alphaImage.write(outfile);
return 0;
}
