dtprocess on-line help
File Open dialog
The File Open file selection dialog lets you
select a header file or an image file with header to load into dtprocess.
If the header is successfully read AND it contains keywords for the dtprocess
widget values, then they are loaded into all the widgets.
If File Save As is selected, then all the dtprocess widgets values are
written to the selected header file, so that you can save a dtprocess scheme
for subsequent sessions.
