TTEngine 4.3 is available for download at its home page. New features: horizontal and vertical font scaling and mirroring. Changes from latest public release 4.1:
* I've placed an open counter in the LoadedFont structure. It removes problems with many RastPorts using one font.
* TT_SetAttrs() function may be now called before TT_SetFont() and is able to create RastPort context.
* TT_SetFont() returns now BOOL value instead of VOID, because it can fail in low memory condition.
* New demo program MoreFonts shows using many fonts at once in one window.
* Affine transformation support code added. (Particular examples of affine transformations are: scaling, shearing, rotation).
* Font may now be scaled in both the axes independently with TT_ScaleX and TT_ScaleY tags. Scaling range is from 0.01 to 100 (negative too, results in mirroring of the text).
* TT_TextExtent() returned random values in the TextExtent structure, if no font has been set for the RastPort using TT_SetFont(). Now the structure is zeroed in the case.
* New demo program Scaling shows - as its name says - font scaling.
* TT_OpenFont() performed illegal READ-MODIFY-WRITE operation at address $0000003A, if opening of the font file failed. Fixed.
* Header file "ttengine.h" was modified to comply with AmigaOS headers standard.

Can't wait to see it integrated with the OS!!! :)

In reply to Comment 1 (pixie):
Patching the system is the next thing to do. V4.4 probably will include optional system patch allowing for using TrueType fonts (antialiased too) in the whole system.

In reply to Comment 2 (Grzegorz "Krashan" Kraszewski):
Sounds terrific.
Has their been any dialog with Hyperion about integrating this as part of an OS release rather than patching the system?

In reply to Comment 3 (anonymous):
Yes, we are in contact. But it seems TTEngine can't be for some technical reasons integrated into the system and it have to be a kind of hack anyway (but not very "heavy"). To make it short - there may be some 100% system compatible applications which fail with TTEngine. TTEngine will be not more a hack than e.g. VisualPrefs is, but can't be 100% pure due to design mistakes in AmigaOS as it is now. To sum it up - TTEngine can be (and I'll be happy if if do) valuable OS4 contribution, but not OS4 component. And to be clear here: TTEngine itself as a shared library IS NOT a hack at all - it is 100% style guide compilant. A path enabling TT fonts in the whole system IS a kind of hack however.

In reply to Comment 4 (Grzegorz "Krashan" Kraszewski):
Isn't patching Text() to use TTengine functionnalities enough to get truetype integrated in the whole OS ?

In reply to Comment 5 (Rafo):
No, Text() is not enough. You have to patch at least Text(), TextLength(), TextExtent(), TextFit(), OpenFont(), CloseFont() SetFont(), and from diskfont.library AvailFonts() and OpenDiskFont(). And I am not sure now if it is all.

In reply to Comment 6 (Grzegorz "Krashan" Kraszewski):
Would patching those interfere with the working of Type1.library?
It's no good having an OS that will only handle Truetype and not Type
1.

In reply to Comment 6 (Grzegorz "Krashan" Kraszewski):
There's also FontExtent(). You could take a look
at AROS sources if you want, whose diskfont.library
BTW: also compiles and works under AmigaOS (including
bullet support).

In reply to Comment 8 (Don Cox):
No. You just make the patch conditional.
IF font to be opened is truetype THEN
DO TTEngine magic
ELSE
CALL original function

Antialiased fonts would be so neat as standard in AOS(4). Ohh well.. We'll have to live with the primitive look it has now then.

In reply to Comment 8 (Don Cox):
No, TTEngine does not interfere with type1.library, to say more it even work simultaneously with ttf.library, digitatruetype.library and others based on bullet.library API. TTEngine does not use bullet and is fully independent.

In reply to Comment 11 (Björn Hagström):
Well, It seems TTEngine patch will work under OS4 (or even MorphOS, why not). Expect first release in two or three weeks.

Ever though about making this available to the AROS developers?
