Visualization with Pico GFX-70 5-15
Bitmap
The bitmap screen element makes it possible to display graphics in the Pico
GFX-70 display that you have made yourself or have purchased. Display and
visibility can change during operation. To do this, you need to associate the
bitmap graphics with Boolean variables.
PicoSoft Pro supports the following bitmap graphic formats:
• Windows Bitmap format (bmp)
• JPEG format (jpg)
• Tiff format (tif)
• Icons (ico)
The formats are converted to monochrome format using suitable conversion
procedures and then saved accordingly in the program. The size and position
of the bitmap graphic can be modified later in the Screen Editor.
Programming in PicoSoft Pro
1. Hold down the left mouse button and drag the Bitmap screen element
into the screen.
This will open the Picture File Selection dialog.
For the optimum display of the graphic file select one of the three
conversion processes provided in the Conversion Type area. The
Preview shows the selected bitmap and the conversion result. PicoSoft
Pro always generates the optimum black and white bitmap graphic for
display on the monochrome Pico GFX-70 display. You can also support
PicoSoft Pro by optimizing the graphic file.
2. Position the mouse over the screen element and move it to the required
position with the left mouse button depressed.
IMPORTANT
Bitmap graphics require a large amount of memory.
Overlaid bitmaps are also stored fully in the memory. The
more bitmaps are used use, the more the cycle time will be
increased considerably due to the additional memory
requirement. This may possibly lead to program
malfunctions (e.g. loss of count pulses).
Black and white graphics should be used ideally. These
should be between 16 x 16 and 32 x 32 pixels in size
