Hello

I have tested the %eq option with a simplified test below:

I don't think that you can do much to improve the outcome. %eq is somewhat limited and I get the impression that it is not often used.

There may be some improvement obtained by using a different font such as

I have done a preliminary investigation with two conclusions:

1) At the moment the font cannot be preset as I suggested above. We could fix this.

2) We could fix the position of the divide line in order to allow for the subscripts.

I will add this to the task list but I am doubtful about the result being what you would like.

Lester,

Here is my approach.

Thanks for the pointers.

Does Clearwin accept SVG files as input?

Lester

[PaulLaidler]

SVG files can be opened and drawn to a "drawing surface" such as that generated via %gr.

See FTN95.chm and search for SVG.

It is under ClearWin+, then Graphics, then Scalable vector graphics.

[arctica]

Thanks for the info Paul.

Shame Clearwin cannot read Inkscape SVG files directly; the structure is slightly different.

I had a look at Ken�s example, and there isn�t a need to �print� to PDF, you can capture the screen image with shift-PrintScreen, the paste into Paint and select and cut the bits you want.

Pasting an image file, defined in the Resources section of a program is great if there�s a convenient area to paste it into, say for the legend of a graph axis. In that case you can keep the space for it clear. It isn�t so good if you overlay it on part of a drawing as the white space around the characters obscures what is beneath. In such a case it is a real pity that %eq isn�t better. If it is a regularly repeated display of an equation, you can use something more sophisticated than Paint to make it an icon or a GIF that has transparency. If it is a �one-off�, then the whole rigmarole of making an image file isn�t really appropriate, and similarly if the equation itself has to be scaled.

There is nothing to stop you creating your equation yourself with multiple �passes' for numerator, denominator, subscripts and superscripts etc, but again, a really nice%eq would make that a lot easier.

Incidentally, whatever happened to the Hershey fonts that FTN77 used to have as part of its graphics support?

[PaulLaidler]

It looks like DRAW_HERSHEY@ is exported by salflibc.dll for Win32 but I don't think that I have ever tested it. I presume that the font must be included in the DLL as a resource in order for it to work.

__win_draw_hershey is exported by Clearwin64.dll for x64 but this is just a place holder for possible future development.

If there is a real chance that these functions might be useful then I can investigate further.

Hi Paul,

Probably not worth investigating, as it is my interest in archaeology!

Interesting though.

A new option %eq[local_font] has been added and some improvements to the display for %eq have been made for the next release of ClearWin+.

%eq[local_font] will use the current %fn and %ts instead of the default "Times New Roman" with a text size of 2.0.

The improvements provide a reasonable layout of the symbols for this particular equation.

%eq continues to be of limited usefulness and alternatives such as %im are recommended.

[DanRRight]

Before %eq was working but the results were looking like a disaster. No greek math symbols. Hopefully new local font option will handle that
