wanted: program to process Windows Font files

[paulel]

has anyone written a program that can process (and display) windows font files?
Thank you.

5 Years ago I did a "tour de force" of accessing Windows font files from a directory listing of Windows fonts. Still works but not a simple demo:

It might be a mod of someone else eg the hot key crap, just press spacebar as alternate quit key along with escape. It also makes a list in Console of files not accessable.    Oh that's not Console that's my own scroller Sub displaying list of fonts not working (This is oldie.)

Put this file, direntry.h, in same folder as your QB64 exe file:

  direntry.h (Size: 1.21 KB / Downloads: 39)

Also the GetFileList sub may have been updated even a couple of times but this one works for me fine, today anyway ;-))

has anyone written a program that can process (and display) windows font files?
Thank you.

BTW there is nothing to process, use FontHandle& = _loadFont( ) with specs, see wiki and then set font to use with _Font FontHandle&

@bplus

Mark,

Didn't you also make a custom font program? I'm curious because I posted how to use two font sizes in one program by making a hardware overlay. For SCREEN 0, that's essential, but with a graphics program custom fonts could be created in a variety of sizes and applied to the same screen.

Pete

[bplus]

I made code for drawing scalable letters (and digits?).

With RotoZoom or even _PutImage you can scale and Rotate any font letters individually or whole text lines or blocks.

[SpriggsySpriggs]

I made something a long time ago on the old forum that would display the font dialog in Windows and after you pick the options it would display some text using the selected options. Worked rather well. Don't know where it is now

[Pete]

Where's Richard? QWERTY. He started keeping all this stuff organized at .rip. "Librarian" dude.

bplus,

been programming for all these years only now learned of the _FONT function.
thank you.

Yeah there are still things I am learning QB64 has!

Steve wanted to introduce the $Pete meta-command. $Pete automatically swaps every indexed QB64 statement to the next indexed statement. That way Steve says when your program runs, you can expect to get the same output every program Pete ever coded would produce.
