ScreenShotΒΆ
Capture PNG or JPEG images of the channel viewer image.
Usage
- Select the RGB graphics type for the snap from the “Type” combo box.
- 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).
- Repeat (1) and (2) until you have the image you want.
- Enter a valid path for a new file into the “Folder” text box.
- 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.
- 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.
