I want to print a number on form canvas. The number is inside a box.

In a procedure I wrote

Var  Rect : TRect;
begin
  Rect := ...
  canvas.font.height := rect.bottom -rect.top - 5;
  textrect(rect.left, rect.top, inttostr(Num));
end;

I found the size of the number was changed with the rect's size, but it's smallest size is about 6,how can I let it smaller?

Hi,
 I think you don 't use a TrueType - Font.

Try to set the font to a TrueType Font:

Var  Rect : TRect;
begin
 Rect := ...
 Canvas.Font.Name := 'MS Song'; <-- Set Font to TT - Font
 canvas.font.height := rect.bottom -rect.top - 5;
 textrect(rect.left, rect.top, inttostr(Num));
end;

Now the smallest size should be 1 !!!

Hi,

The MS Sans Serif is not a TrueType Font.

If you want to know if a Font is a TrueType Font
you can look at the FontDialog.
Just klick on [...] at the "FONT" Property of any
component which used this property.
If a TT-Glyph will be display on the left side of the
FontName (in the ListBox) then it is a TrueType Font.
