36 Graphic Images
Publication 2711E-820 – January 1998
Tip: Convert two-color bitmaps to monochrome before you import
them. Monochrome images use less memory and therefore provide
better runtime performance. You can configure a monochrome
image’s foreground and background colors, fill style, and blink
attributes. You can’t change the format of 16-color images.
Tip: Because PanelBuilder converts color images to 16-color
bitmaps, a 256-color image may not convert as expected. To achieve
a photographic appearance for your color bitmaps, import images
that use few colors. Screen 10 of the demonstration applications
shows a good example: TANK16.BMP uses grays and greens and
has the quality of a photographic image. If you followed the default
installation, the demonstration application files are in the
PB1400E\DEMO folder.
Once bitmaps and .dxf files are imported into the application’s
graphic image libraries, you can select the files and place them on
the application screen or in objects as labels.
Sizing Graphic Images
You can increase or decrease the size of the graphic images once you
place them on screens in PanelBuilder. You can use multiple copies
of the same graphic image and change the size of any or all of them.
The size of the source image remains unchanged; PanelBuilder saves
each new size of the image as a separate graphic when the
application’s .pvd file is created.
Note: The application’s size increases each time you resize an
image. Limit the number of images you resize to ensure that your
application will fit in the terminal’s memory.
Copying and Exporting Graphic Images
If you copy a graphic image to another PanelBuilder application, its
size attributes are copied as well. If you export a graphic image, it is
exported with its original size dimensions, or with the size 640 by
480 pixels, if it was originally larger than this. When exporting, if
the source image was a .dxf file, the exported file is a bitmap (.bmp)
representation of the source image.
