Process with arguments doesn't work...

[Gerd]

Think you are missing a "/" after

[mrjj]

@Gerd
Good catch!
yes seems filename will be directly appended.

[Gerd]

Sorry, last post was incomplete...
Think you are missing a "/" after "Messages" and before filename in this Line:

arguments << "convert -density 300 -trim" <<"//DGS1109N007/Affichage/Messages"+filename<<"-quality 100 "<<"//DGS1109N007/Affichage/Display/Messages/output.jpg"

@mrjj You are right, magick don't like / but qt don't like \ then, I don't know...

@Gerd Hi Gerd, Yes, the / was missing, now I receive something, but error and not expected conversion...

magick.exe: UnableToOpenBlob 'convert -density 300 -trim': No such file or directory @ error/blob.c/OpenBlob/3490.

what mean what say mrjj, magick don't accept / but expect ...

I will try replace.("/", "\") to see what append..

[Gerd]

try to check what is in arguments, it seems that you also miss a blnk after "...trim"

@Gerd Hi Gerd,

I found how make it work:

program=QDir::toNativeSeparators("//DGS1109N007/Echanges_SAA/Affichage/Display/imagmagick/magick ")+ "convert -density 300 -trim "+ QDir::toNativeSeparators("\"//DGS1109N007/Echanges_SAA/Affichage/Messages/"+filename)+"\" -quality 100 "+QDir::toNativeSeparators("\"//DGS1109N007/Echanges_SAA/Affichage/Display/Messages/output.jpg");

now I have an other strange thing not linked with this topic...

with:

QDir directory("//DGS1109N007/Echanges_SAA/Affichage/Messages");
    QStringList images = directory.entryList(QStringList(),QDir::Files);

    for(int i=0;i<images.count();i++) {
    //do whatever you need to do
    QString filename=images[i];
    qDebug()<<"filename"<<filename;

    program=QDir::toNativeSeparators("//DGS1109N007/Echanges_SAA/Affichage/Display/imagmagick/magick ")+ "convert -density 300 -trim "+ QDir::toNativeSeparators("\"//DGS1109N007/Echanges_SAA/Affichage/Messages/"+filename)+"\" -quality 100 "+QDir::toNativeSeparators("\"//DGS1109N007/Echanges_SAA/Affichage/Display/Messages/output.jpg");
    myProcess.start(program);
    myProcess.waitForFinished(10000);
   
    }

the conersion is made only with the first file, but the qDebug()<<"filename"<<filename; print all files...

I try to put some waitForFinished but same result...

@filipdns
Hi
but dont you save all input files to the same filename (output.jpg) ?

[filipdns]

@mrjj hi, not, imagemagic rename output file itself like ouput-1.jpg output-2.jpg

@mrjj I openned an other topic for this problem because it's not linked with the title ;-)
