Macro: SavePAL

After you have created a palette you like, you can save it to a .PAL file by clicking on this button. You may also want to save several intermediate steps if you are creating a complex palette, so you can return to a known point if subsequent steps don't turn out just right.

You may want to use different palettes for different Spectrogram applications. For example, if you are going to print the screen with a black-and-white printer, you may want a simple grey-scale palette just for that. You may find that certain palettes look better on certain digital projectors or laptops.

Or you may want your results to be easily compared to others that used a certain palette. For example, many older spectrograms were made with special equipment that used thermal paper; spectrograms were black on a white background, with higher levels (more heat) corresponding to darker blacks.

If you have made changes to a palette during a session but haven't saved it, you will be prompted to do so when you exit Daqarta.

Macro Notes:

The SavePAL= macro has no effect if any File Open or Save As dialog is already active.

SavePAL= without a name will pop up the Save As dialog showing all PAL files, but with no default name.

SavePAL="MyFile" will pop up the Save As dialog with the default name set to MyFile. (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 MyFile.PAL. If that file already exists, you will be prompted to replace it.

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

SavePAL=">Field1" will use the contents of Field1 as the default file name, and A.SavePAL=">Field1" will save using that name directly.
