getImageByURL

public static org.eclipse.swt.graphics.Image getImageByURL(URL url)

This method extracts the base filename out of the given URL and uses it as key to search for the Image in the ImageRegistry. If the Image is not yet present it will create the Image instance and register it automatically. On creating and registering it will respect dpi scaling.

Parameters:

url - The URL of the image for initial loading.

Returns:

The Image representation of an image external to NatTable.

See Also:

• getImageByURL(String, URL)

getImageByURL

public static org.eclipse.swt.graphics.Image getImageByURL(String key,
 URL url)

This method returns the Image that is registered for the given key. If there is no Image registered for that key already, it will create and register the Image that can be loaded by the given URL.

This method returns an Image that matches the dpi settings. If the dpi of an axis is bigger than 96 it will search for an image for the bigger dpi. For this the filenames need to carry the dpi information.

For example if you request checkbox.png this method will search for a scaled version relative to the requested image. The following will give an example on the scaled files:

• checkbox.png
• checkbox_120_120.png
• checkbox_128_128.png
• checkbox_144_144.png
• checkbox_192_192.png
• checkbox_288_288.png

If the matching scaled version is not found, it will automatically upscale the base image.

Note: If you want to get the image later again you can directly use JFaceResources.getImage(key).

Parameters:

key - The key under which the resource is registered in the image registry.

url - The URL of the image for initial loading.

Returns:

The Image representation of an image external to NatTable.

getDisplayImageByURL

public static org.eclipse.swt.graphics.Image getDisplayImageByURL(URL url)

This method extracts the base filename out of the given URL and uses it as key to search for the Image in the ImageRegistry. If the Image is not yet present it will create the Image instance and register it automatically. On creating and registering it will respect display dpi scaling.

Parameters:

url - The URL of the image for initial loading.
