I would use a small script:
Edit the OutputDir
line at the top to specify the folder you want. (I'm assuming ..........
was a placeholder, not the actual path you want.) Remember to double backslashes in that path.
function OnClick(clickData)
{
// Remember to double backslashes in paths.
var OutputDir = "C:\\My Output Folder";
var BmpArgs = "WIDTH=1500 HEIGHT=1500 ADDSUFFIX=_1500px NOENLARGE PRESERVEASPECTRATIO";
var JpgArgs = "QUALITY=90";
var TempDir = DOpus.FSUtil.GetTempDirPath();
if (DOpus.TypeOf(TempDir) != "object.Path")
return;
var cmd = clickData.func.command;
cmd.RunCommand('Image CONVERT=bmp TO="' + TempDir + '" ' + BmpArgs);
cmd.ClearFiles();
cmd.RunCommand('Image CONVERT=jpg FROM="' + TempDir + '\\*.bmp" TO="' + OutputDir + '" ' + JpgArgs);
// Our temp dir will be deleted automatically after a few minutes, but we may as well clean it up now.
cmd.RunCommand('Delete QUIET NORECYCLE FILE="' + TempDir + '"');
}
