Working with colors description
Color (red, blue, etc.) has no defined data type. It is possible to specify it by various ways by means of the
String or
Long data types.
In the PROMOTIC system the color is entered as
RGB String the same way as, for example, in HTML syntax.
It is a text beginning with
"#" followed by (in hexadecimal) 2 digits for
Red color compound, then 2 digits for
Green color compound and then 2 digits for
Blue color compound.

"#RRGGBB". For example:
"#00ff00" is light green
"#ff0000" is red
"#d000d0" is magenta
Some properties (of "color" type) support transparency. In this case instead of
RGB String the word
transparent can be used. It is usually used for
Pmg object background color, e.g.
PmgBox.ColorItem.
For color transformation the folowing methods can be used:
-
Pm.ColorRgb: Returns the color by entering the three RGB components
Colors can be set/read from properties of many graphics objects. For example
PmgString.ColorText,
PmgBox.ColorItem,
PmgBar.BarColor,
PmgButton.ColorText,
PmgPipe.ColorItem,
PmgRectangle.ColorBorder,
PmgEllipse.ColorItem,
tvGraph.Color,
PmForm.BgColor,
PmgWTable.SetCellBackColor.
