Using Background Graphics 16–16
When creating graphics, consider the following:
• Freehand drawings are memory intensive. For complicated
drawings, create a bitmap graphic of the drawing with another
source program and then import the graphic.
• Circles process more efficiently in the terminal than ellipses. Use
circles whenever possible.
• Imported bitmaps are handled like global objects. The terminal
stores only one copy of a bitmap image regardless of the number
of links to it in an application.
• Imported bitmaps cannot exceed the number of pixels supported
by the terminal display. Larger bitmaps are cropped.
• You can import/export monochrome or color bitmaps.
• On color terminals, full color bitmaps are imported as standard 16
EGA color images. If the bitmap contains more colors, each color
is mapped to one of the 16 standard colors.
• On grayscale terminals, full color bitmaps are imported as 4 color
(shades of gray) images.
• Color bitmaps are exported as they are stored in PanelBuilder. If
a full color bitmap was reduced to 16 or 6 colors when imported,
it is exported in the same format.
• When using graphics with control objects, use the Move Dynamic
Objects Front command after completing an application screen.
The screen will then appear the same as it would on the
PanelView terminal.
