Save Main Colors File

Controls: Edit Menu >> Colors & Line Styles >> Save File
Macro: SaveRGB

If you want certain color and style setups for special applications, this button allows you to save them for future use. The setups are saved as .RGB files, which include not only colors but also Line Width and separate Line Styles for each Input and Output channel.

Setups you create can be loaded later via the Load File button discussed below, as can Default.RGB to restore the original Daqarta colors and styles.

Macro Notes:

SaveRGB= without a name will open the Save As dialog showing all .RGB files, with the default set to Colors.

SaveRGB="MyColors" will open the Save As dialog with the default name set to MyColors. (Note that quotes are needed around all filenames in macros.) If you accept this by hitting Enter or the Save button in that dialog, Daqarta will assume you want to save a file named MyColors.RGB. If that file already exists, you will be prompted to replace it.

After either of the above commands, you may use IF.Posn?f=0 to see if the user has hit Cancel or [X] instead of choosing a file name. This allows your macro to exit gracefully or take other action.

A.SaveRGB="MyColors" will save MyColors.RGB directly, without any Save As dialog. Note that if the file already exists, it will be overwritten without any confirmation prompt.

SaveRGB can use string variables and expressions. For example, SaveRGB=Field1 will use the contents of Field1 as the default file name, and A.SaveRGB=Field1 will save a file with that name directly.
