Driving InstructionsThe label is "painted"
using the formulae in the listbox center top, which can be selected by
double-clicking on the chosen formula. The chosen formula then appears in the coloured listbox and becomes the surface-most in the label space.
It starts out black, but you click on its formula in the coloured listbox to activate the colour bars for each formula.
The coloured list starts with two entries "border" and "1". "Border represents the label border
and can be adjusted like any other frame border, for relief=flat,...,groove, colour and borderwidth.
Relief and borderwidth apply only to the border and can be adjusted at any time.
The "1" is a formula representing the whole of the label space. It and all the following formulae in the list
down to the last surface-most formula can be selected and adjusted for
If you discover that you have a redundant formula in the list, select it by clicking on it and use the "Delete Formula"
At any time you may adjust the width and height of the label image. These are often best kept equal
to maintain a square, but all sorts of rectangles are possible and effective.
The library of funtions is both limited and fixed. It is limited to simple
quarters and quadrants of the image space. It is also fixed in that the functions cannot be altered.
You can however take this whole html page and put your own functions into the function listbox
and experiment. Take care that the functions must be in a form acceptable to Tcl. Tcl's
conventions are almost identical to the C conventions for expressions.
Response for selecting the formulae in the lists is about 1 second, so
dont try to work fast with the painter. If you are using Windows 3.x
the response can be a lot slower, presumably due to 32 bit emulation.
When you are done you can save the generated code in the Tcl Temp file named "labelbar.txt".
