20.6.18 Bitmap
You can do the following settings in category 'Bitmap' in the visualization element
configuration dialog box:
Specify, which image file should be used. This specification can be static or dynamic. If
there are entries both in the 'Bitmap' field and in the 'Bitmap Variable' field, then that
in the 'Bitmap' field will be ignored:
Bitmap: Static definition: You can enter the path of an image file available in the local
file system. Via button ... the standard dialog for browsing for a file will be opened,
where you can select the desired file.
Bitmap variable: Dynamic definition: A project variable of type STRING can be entered
here, containing the name of the image file currently to be used. This allows dynamic
change of images in online mode, but only works with image files which are entered
in the project-global "bitmap list" (see 'Extras' 'Bitmap list'). The string-variable always
only must get assigned the file name, even if there is a full path specified in the
bitmap list.
See in the following example 'stBitmap' as string-variable, which is got assigned
various image files that are part of the global bitmap list.
CASE nId OF
0: stBitmap := 'background.bmp';
1: stBitmap := 'deutest.bmp';
2: stBitmap := 'alarm.bmp';
END_CASE
If stBitmap e.g. is declared in object PLC_PRG, it can be entered here in the
configuration dialog in field 'Bitmap variable' like follows: „PLC_PRG.stBitmap“.
The following entries affect the frame of the bitmap:
• By selecting Anisotropic, Isotropic or Fixed you specify how the bitmap should
react to changes in the size of the frame. Anisotropic means that the bitmap
remains the same size as the frame which allows you to change the height and
width of the bitmap independently. Isotropic means that the bitmap retains the
same proportions even if the overall size is changed (i.e., the relationship between
height and width is maintained). If Fixed is selected, the original size of the bitmap
will be maintained regardless of the size of the frame.
• If the Clip option is selected together with the Fixed setting, only that portion of
the bitmap that is contained within the frame will be displayed.
