Using Still Store Loader
Using Background Matte
Background Matte is a download feature only. The selected matte color is
applied by the target device to the portions of the raster not occupied by the
downloaded image.
To add a background matte to a downloaded image:
1. Go to the Image Transfer dialog box by clicking the
Upload/Download
button on the main application menu.
2. Click on the
Background Matte
check box to open the Select Matte Color
dialog box.
3. The matte color can be selected in two ways:
a. You can choose a pre-defined matte color by clicking on one of the
labeled radio buttons.
b. You can create a custom matte color by entering Y, Cb, and Cr Hex
values in the labeled window areas.
The Y, Cb, and Cr values of the color will be indicated in Hex, and a
sample of the selected color appears in the display area at the bottom of
the window.
4. Click
OK
to accept the matte color. The window will close and the
Background Matte radio button in the Image Transfer dialog box will
be selected.
You can now download an image to the Zodiak Stillstore. The matte and
new image will completely overwrite the existing Stillstore page.
Note Once a matte has been added to a framestore page it is incorporated into the
image. If that framestore page is uploaded back to Still Store Loader, the
uploaded image will be full raster containing pixels of the matte color.
To disable the background matte function, click on the Background Matte
radio button to clear it.
