Process to edit fonts

[khimani_mohiki]

We currently use FONT on our drawings and we have an issue with the 1, I(i) and lowercase L being visually in indistinguishable. So we are looking to use ISOFONT instead, however this has an issue with the spacing of some letters.

So I would like to edit the ISOFONT to reduce the spacing between certain characters, I have gotten as far as:

1. Create new directory, add decompile_font.exe, compile_font.exe, isofont.fnt, ucore46.dll & udata46.dll

2. decompile the ISOFONT.fnt using:

decompile_font.exe isofont.fnt newisofont.fnt

3. edit the decompiled NEWISOFONT.fnt

4. recompile NEWISOFONT.fnt TO ISOFONT.fnt using:

compile_font.exe newisofont.fnt isofont.fnt

5. Move isofont.fnt into Common Files\x86e_win64\text\usascii

However when I re-launch Creo and try to change some text to the edited ISOFONT I get this error:

Font isofont.ndx.ndx can not be loaded

I presume this is a compiling error as I haven't touched the ndx file, if I understand correctly the ndx file just gathers various fnt files? Can someone shed some light on it please, I haven't been able to find any documentation on how to edit fonts, Im just making it up as I go along.

Many thanks

Hi,

I compiled Creo fonts in the past.

1.]

In Creo 5.0 installation I can find isofont.fnt file in Common Files\x86e_win64\text\usascii directory

2.]

In Creo 5.0 installation I can find isofont.src file in Common Files\text\usascii directory.

This means you do not need to run decompile_font.exe

3.]

In Creo 5.0 installation I can find isofont.ndx file in Common Files\text\usascii directory.

It contains 3 rows:

isofont.fnt
special.fnt
latin_1.fnt

4.]

To compile modified src-file I used following commands in Command Prompt window:

set COMPILE_FONT_PMT=36
compile_font.exe   isofont.src   isofont.fnt

what does "set COMPILE_FONT_PMT=36" do?

Hi,

in the past this setting wasd mandatory to get 64-bit version of compiled font.
