A.10.1.15 Display Cutout Image

Configuration for Display Cutout Image action

Configuration for Display Cutout Image action

This option presents an easy-to-use way of popping up a cutout image from an image server displaying a region of sky around an activated row. The size of cutout can be selected, and a small selection of image services is provided. When you activate the row, the program will attempt to contact the web server which provides these images, retrieve the image, and display it in one of the internal image viewers.

Note: the options provided here are not very extensive; the list of image services is rather limited and the image viewer is not configurable. This action may be replaced or enhanced in future releases to provide a more capable image cutout display action.

Configuration:

RA Column
Dec Column
Identifies the table columns representing sky coordinates for the central cutout position.
Cutout Service
Select which of the provided cutout services will provide the displayed image. The list is currently:
Dimension in pixels
Gives the number of pixels (width and height) of cutout images. The text to the right of the selector indicates the size of a pixel for currently selected service.
