A step-by-step recipe to make a post-script plot of your image

This section gives a detailed description on how to get from your image on disk to a publishable PS file just using the GUI.

Let's say we have an image called ngc253.fits:

1. Starting the viewer

   To start the viewer type viewer at your Unix command line.

2. loading the image into the viewer
   • In the data manager window select the file ngc253.fits.

   • On the right-hand side click on Raster image. The image will now be displayed on the display panel.

   • Click on the Done button to finish with the data manager.

3. Adjust (fiddle) the colormap

   The displayed might not show a nice contrast. You can use the colormap fiddling tool to adjust this.

   • This is by default associated with the middle mouse button, so move your cursor onto the image and drag the cursor across the display while holding the middle mouse button down. Release when you are happy with the result.

4. Turning on axis labels
   • Click on the Adjust... button at the bottom-left of the display panel.

   • click on the roll-up Basic settings to roll it up.

   • click on the roll-up Axis labels to roll it down

   • press the menu button next to Axis Labelling & annotation and select True. The axis labels will appear on the display panel.

   • press the Dismiss button at the bottom of the adjustment gui to hide this window.

   Your axis labels might be cut off right now or you think that there is too much space around them. In this case you should go to point 4, otherwise continue skip this.

5. Adjusting the axis label space
   • On the display panel select Canvas manager from the File menu

   • press on Geometry to roll this rollup down.

   • use the sliders to remove excess or add extra space.

   • press the Done button at the bottom of the canvas manager gui to remove this window.

6. Printing the image/ save it to a PS file
   • press the Print... button at the bottom of the display panel.

   Now either save it to a file:
   • enter a filename in to the first field (Output file) of the canvas print manager AND(!) hit return.

   • press the Save PS button at the bottom of the gui.

   or print it directly:

   • press the Print button at the bottom of the gui.

   • in the new window select either Ghostview or a Printer with name.

   • if you want to delete the underlying postscript file after printing check the box Remove after printing

   • press the Print button

7. press the Dismiss button on the canvas print manager window.

That's it you have successfully create a post-script file of your image. You might have noticed all the other options you have in the Adjust panel. Just play around and look what they do.
