GetFontDescription() on Windows and Mac

fwilleke80

Hello,

I am using GeClipMap::GetFontDescription() to retrieve a BaseContainer with data that I can use to draw nice looking text into a GeClipMap.

This is the code on Mac:

	BaseContainer fontSettings;
	if (!GeClipMap::GetFontDescription(String("Helvetica Bold"), GE_FONT_NAME_POSTSCRIPT, &fontSettings))
		return false;

This is the code on Windows:

	BaseContainer fontSettings;
	if (!GeClipMap::GetFontDescription(String("Arial"), GE_FONT_NAME_POSTSCRIPT, &fontSettings))
		return false;

On Mac, it works just fine. It is very fast (I actually do this call from within SceneHookData::Draw() with no performance issues). On Windows, this call needs almost a second to finish, and then always returns false. Why?

I tried with different font names on Windows ("Arial", "Courier", "Segoe UI" (which is the one Cinema 4D is using for its UI)), no success. GetFontDescription() always returns false.

Hi,

there is definitely something broken here for Windows and it seems to go deeper than just GetFontDescription. I have to go now, but this is how far I got:

EDIT: FYI, I am aware that you are on C++

I just found one possible solution: Just ignore the return value of GetFontDescription(). It returns false, but if I use the data from the container anyway, I actually can draw text successfully. Strange...

Thanks for testing this, @zipit ! Hope to hear something from the SDK Team about this, too

That really does look fishy.

GeClipMap::GetFontDescription()

hi,
on both OS, this function will only work with the flag GE_FONT_NAME_POSTSCRIPT

on mac, it does almost nothing, it just pick the name passed as argument and insert it in the BaseContainer at ID FONT_POSTSCRIPT_NAME
this function will return false only if you use another flag.

on windows,
it does use the function EnumFontFamiliesExW (from microsoft). As written on this page it does create a LOGFONTW

It's calling another function that will feed the basecontainer it will only work with font type == TRUETYPE_FONTTYPE or DEVICE_FONTTYPE. Other cases it will return false.

If it's a familly it will loop to retrieve all the fonts.
If not it will return the informations.

So this look like a bug, I'll ask the dev team why on OSX it does nothing.

By the way, the Draw function isn't the right place to do this even if it's fast on osx.

Cheers,
Manuel.

hello,

fast reply, confirmation it's normal.

The name used to select a font on macOS is its postscript font name, hence nothing to do here. On Windows you have to enumerate all fonts to find the right one and get the postscript name of its 'post' table.

Cheers,
Manuel

Manuel

hi,

without further feedback i'll set this thread as solved tomorrow.

Cheer,
