No more from me!

But here is a proper style sheet, exmaple doc and sample pdf. 

I found out that graphics can contain other graphics, so i was able to render the dice by composing the dots with a generic border that can go around any gr-geometry!

These dice are now the same size as the current font and properly rendered to the baseline. I use carc to draw a circle so the dot size changes properly according to the dice size, and so does the dice border.

Hope you like it. Next time you see it I will have committed it to texmacs.

it should be easy enough for you to compose a dice with a ? in it if you need.

This uses a scale properly for coordinates of the dots, and offsets the border within the frame by the width of the line so that we get all of the line and proper corners.

However I note that if I click on the VIEW menu when this file is loaded, that texmacs crashes!

My final imrovement will be to use circles instead of points, so that the dice will scale properly with the font size.

Attached is a better dice, with rounded corners. It should NOT have been this hard to do.

Maybe this definition for arc is suitable for geometry, but it is not a useful drawing primitive. Also how weird that a circle can't be defined by a centre and radius, but instead by three points on an enclosed triangle. Likewise a pie-wedge shape must be constructed from an arc and two other lines to the centre.

Another difficulty was that terms in a <graphics> tag have to be separated by | explicitly, something which is unnatural when one is used to the implicit <concat> tag for text. It's NEARLY impossible for me right now to emit a usable <graphics> tag with a variable number of items - I mean how does one generate a round-rect macro that can be successfully emitted in a graphics tag? Using quasi unquote* ? How is that going to work with the drawing editor?

Also, the thickness of the arc line appears to be greater than the thickness of the horizontal line. Maybe that is because half of the horizontal line is truncated, I should have allowed a margin, I may do later.

Attached is an example.

It defines dice-1 .. dice-9, and also <dice|x>

I had quite a few problems with programatic graphics elements so I settled for the first one that worked.

I am not able to work out how to use the arc tool to draw a quarter circle, so the dice are all square, but if you can do it, just re-define dice-square macro.

It should probably have a border around the square.

Also, although the dice size increases with font size, the size of the dots do not. I don't know why this is.

The graphic tool does not make much sense to me. I can't even draw a pie using the circle tool, only a chord.

hi everyone
when typing some maths for secondary schools, we often use the six faxes of a cube:

do you think there could be a sort of macro to type such characters into texmacs ?
