thanks

Hi airpas,

how to shrink the space between characters?

There is currently no property for that. Fortunately it can be "hacked" in using a expression.

In order to adjust the letter spacing for text that uses Left alignment, set the RenderCharExpression property to the following expression.

Code: Select all

const float spacing = 0.5;

if(CharI)CharX -= spacing;

And for text that uses Center alignment, use this instead.

Code: Select all

const float spacing = 0.5;

CharX -= CharI ? spacing : length(this.Text)*-0.5*spacing;

Or in case you want to support both, you can use the following.

Code: Select all

const float spacing = 0.5;

if(this.Align)
{
  if(CharI)CharX -= spacing;
}
else
{
  CharX -= CharI ? spacing : length(this.Text)*-0.5*spacing;
}

Simply set the spacing constant to the value of you choice ( letter spacing is halved when it's set to 0.5 and doubled when set to 2 ).

thanks Kjell , its much better now .

In some of my projects I also used proportional character spacing. The trick is to store width of characters in a separate persistent array. I usually use the CBFG (Codehead's Bitmap Font Generator) which is able to produce such a list of character width values. Loading to excel, transpose the table, copy and paste to ZGE's array... that's it.

See the attached screenshot. In this concrete case I used the RenderCharExpression like this:

this.CharX -= this.CharI > 0 ? (64 - CharacterWidth[ord(substr(this.Text, this.CharI-1, 1)) - 32]) * 0.015 : 0;

Of course if you will try it, you can use different constants for different fonts.
