      but what did it report ?
      Its impossible to guess what is wrong with no extra info.
      and that function is how QProcess tells how it went.

      btw. i can see
      magick.exe so that seems like windows.
      but you are giving it linux paths as parameter
      "//DGS1109N007/Affichage/Messages"

      windows uses \ and not / so not sure magick.exe likes it.
      also in your sample for .bat, you are using the \ version.

          Good catch!
          yes seems filename will be directly appended.

            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..

                  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...
