Bitmap Example Program 3 – Overlaying Bitmaps

The program consists of three screens that you can select via the up and down

cursor buttons. The screen change is defined in the Button editor (see Button

Editor on page 5-37).

This program illustrates the overlaying of bitmaps in a screen. The circuit

diagram uses six on-delayed timing relays (T01 to T06), that activate outputs

Q1 to Q4 and LED 3 in succession after an elapsed time. This operation is run

in a continuous loop since timing relay T06 resets all timing relays after a set

time.

Standard path: C:\Program Files\PicoSoft 6 Pro\samples\

Program: Bitmap_automatic screen change.e60

Screen 1 - The first screen contains five half-overlaid bitmaps. These are

activated via the outputs Q1 to Q4 and marker M01, and appear in the display.

The half overlaid bitmaps are activated in succession. The Covered option is

selected in the Background area of the Display tab, therefore causing the

overlaid part of the bitmap to be covered by the bitmap in front of it. In this

way it is possible to create the impression of a moving arrow.

Screen 2 - The second screen contains five overlaid bitmaps with each

subsequent bitmap being larger than the previous one displayed. The

individual bitmaps are made visible in succession via the outputs Q1 to Q4 and

the marker M01 (break contact bit logic). The Covered option is selected in the

Background area of the Display tab, therefore causing the overlaid part of the

bitmap to be covered by the bitmap in front of it. In this way it is possible to

create the impression of a moving and expanding arrow.

Screen 3 - The third screen contains five fully overlaid bitmaps. These are

made invisible in succession from the top to the bottom via the outputs Q1 to

Q4 and the LED 3 (make contact bit logic). The Covered option is selected in

the Background area of the Display tab. The overlaid section of the bitmap is

therefore not visible.
