ScreenShot

ScreenShot plugin

Capture PNG or JPEG images of the channel viewer image.

Usage

  1. Select the RGB graphics type for the snap from the “Type” combo box.
  2. Press “Snap” when you have the channel image the way you want to capture it.

A copy of the RGB image will be loaded into the ScreenShot viewer. You can pan and zoom within the ScreenShot viewer like a normal Ginga viewer to examine detail (e.g., see the magnified difference between JPEG and PNG formats).

  1. Repeat (1) and (2) until you have the image you want.
  2. Enter a valid path for a new file into the “Folder” text box.
  3. Enter a valid name for a new file into the “Name” text box. There is no need to add the file extension; it will be added, if needed.
  4. Press the “Save” button. The file will be saved where you specified.

Notes

  • PNG offers less artifacts for overlaid graphics, but files are larger than JPEG.
  • The “Center” button will center the snap image; “Fit” will set the zoom to fit it to the window; and “Clear” will clear the image.
  • Press “1” in the screenshot viewer to zoom to 100% pixels.
