Image Crop The I MAGE C ROP object produces a slider or an Up Down box that allows
operators to crop visible portions of the image on the keyer without
affecting the asset itself.
The Image Crop object’s S LIDER A PPEARANCE property determines if the
control is a slider (T RUE ) or an Up Down box (F ALSE ). If the Slider
Appearance property is set to T RUE , the O RIENTATION property determines
whether the slider is horizontal or vertical.
The C ROP T YPE property determines if the left, right, top or bottom portion
of the image is cropped.
The following example demonstrates a K EYER V IEWER object and four
I MAGE C ROP objects that allow us to view and control the cropping of the
image that is loaded on the keyer. The cropping area is displayed with a
diagonal hatching and the colour of the image is inverted.
Keyer Viewer The K EYER V IEWER object previews on the panel, the currently loaded
media content or video input as it will appear on the keyer when taken to
air. The Keyer Viewer object is often used in conjunction with other objects
that allow you to load, position and format the media onto keyers, like
M
EDIA S ELECTOR , I MAGE P OSITION and I MAGE C ROP objects.
Note: In Production mode, clicking a precise point in the Keyer Viewer
moves the image to that position and the Image Position object’s values
are immediately updated.
