Graphics

The UPX-2 features PNG image support, which enables translucent objects to be
placed over still images (such as background). The dynamic graphics feature enables
the display of images (pictures, CD cover art, etc.) that are hosted externally on a
flash memory card or media server.
PNG Graphics
The PNG file format utilizes lossless compression, meaning image data is not lost
when saving or viewing the image.
PNG format uses an alpha channel (one byte of extra data per pixel) to represent the
pixel's transparency level. A PNG image with alpha is capable of 256 levels of
transparency. Text and images can be antialiased so that sharp curves will look good
against any background. You can apply a true drop shadow that fades into the
background, and create images that take any shape or form. There are many
possibilities with alpha transparency.
PNG images are displayed with full translucency in VT Pro-e and on the panel.
Dynamic Graphics
Dynamic graphics allow an image to be dynamically updated at run time.
Dynamic graphics are updated either automatically, based on the specified refresh
rate, or by sending a new file path to the panel from the control system. The
following UPX-2 objects can have dynamic graphics:
•
Images
•
Buttons
•
Page backgrounds
•
Subpage backgrounds
•
Popup Window backgrounds
The image size and position set at design time will be applied to the dynamic
graphics. Dithering and transparent (bleeding) color are not supported by dynamic
graphics. To help configure the dynamic image position and size at design time, a
"dummy" image (e.g., Crestron Dynamic Graphic.jpg) will be used for previewing
the image layout if no image is selected. Dynamic graphics on an image object will
always be stretch-fitted.
Dynamic graphic properties are assigned in VT Pro-e by double-clicking on the
object.
