Discussion Overview

The discussion revolves around issues encountered while using the astro imaging program ds9, specifically related to saving images with a coordinate system and the functionality of the program on a Mac. Participants explore potential solutions and alternatives for image editing and exporting.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant expresses difficulty in saving images as PNG or JPEG with the desired coordinate system in ds9 and seeks advice from others with experience using the program.
  • Another participant suggests using a screenshot as a workaround, questioning the editability of screenshots compared to images produced by ds9.
  • A later reply agrees that screenshots may be a better option due to time constraints and emphasizes that screenshots are editable, contrary to a prior assumption about their limitations.
  • One participant comments on the general compatibility issues of astro imaging programs with typical home computer operating systems, sharing their perspective on the challenges faced.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best method to obtain images with a coordinate system, and multiple viewpoints regarding the use of screenshots versus ds9's export functionality remain present.

Contextual Notes

There are limitations regarding the functionality of ds9 on Mac, as well as uncertainties about the editability of screenshots versus exported images from the program.

Who May Find This Useful

Users of the ds9 program, especially those working on astro imaging and needing to incorporate coordinate systems in their images.

Hi there,

I am having a lot of struggles with program. I am not using this for any true kind of publication but more so we can reference material. However, it is very important that I have a coordinate system where I can plot the WCS. Whenever I try to save as a PNG or JPEG it does not function as I would expect. It basically prevents me from making either. I learned I can try to export which works at times but does not appear to have a coordinate system. Any ideas on how to deal with this issue from anyone that has experience with the program? Is it possible to create an image with a coordinate system? I am running it on a mac.

If you can't figure it out, would a screen shot work?
 
Haha actually, I think that would be the best thing to do since this is time sensitive. My advisor was under the impression that screenshots aren't editable but I'm pretty positive I can fiddle around easier with a screenshot than anything being produced by ds9 right now. Also, I don't think current image states are saved which is a bummer.

Screenshots are just as editable as any other image, they get saved to your desktop and you can open them in GIMP/Photoshop...
 
The problem with AP programs is they often do not play well with typical home computer operating systems - just my 2c worth.
