Bezier curves and brush styles in EnumEMFFunc
Hi,
this PDF Engine is very good - many thanks for that. Would it be difficult to implement support for PolyBezier, PolyBezierTo and for hatched brush styles (bsFDiagonal, bsHorizontal, etc.) into the EnumEMFFunc function?
Best regards,
Roman

Re: Bezier curves and brush styles in EnumEMFFunc
First feature should not be too difficult.
A conversion similar to the EMR_POLYLINE commands could be used.
The CurveTo*() functions could handle it for the PDF generation.
For additional brush styles, the corresponding pdf commands are not existing yet.
Could need more work to implement it.

Re: Bezier curves and brush styles in EnumEMFFunc
Thanks for the info.
So, I will try to implement the bezier curves support by myself, but I am aware, that the "brushes" are beyond my PDF knowledge and my time capacity. Is there a chance that you (or someone else) could add this feature ?

Re: Bezier curves and brush styles in EnumEMFFunc
My time capacity is a bit restricted also... 
Perhaps Ondrej already has some ideas about implementing it.
He found out several issues and nice workarounds in the past, and may also need this functionality...

Re: Bezier curves and brush styles in EnumEMFFunc
I've made some rough update in SynPdf: it should now handles EMR_POLYBEZIER* commands in conversion from meta file content.
See http://synopse.info/fossil/info/25d9980754
But I didn't test it on much content.
Feedback is welcome!

Sorry, I'm now very happy with SynPDF as it is. Everybody has a restricted time capacity
Of course! 
I've added beziers curve capabilities enumeration in the latest version.
Need some deeper testing, certainly.

Re: Bezier curves and brush styles in EnumEMFFunc
Many thanks for the update. I will test it and let you know soon.
reddwarf: Sure, I like this engine very much too. :-) But our service, that we used the engine for, needs exactly these two features (hatched brushes and curves) to provide more stylish results. It is a generator of printable tournament brackets ( http://www.be-precision.com/draws/ ), and our users prefer a monochromatic or gray-scale output with hatch rather than colored draws.
In all the cases, thank you for the info.

Hello!
Yes, "polybezier" functions are fully functional for my purposes. Thanks a lot!

Re: Bezier curves and brush styles in EnumEMFFunc
Hi everyone,
I used this PDF engine too and I'm glad about functions that are implemented.
But I'm searching for an function/procedure to draw arcs in the PDF, but I only found CurveTo*().
Is this the correct method to draw the required things?
Requirement:
- at least 2 specific points (up to 3 points) are known
- I need a normal round arc without any specific behaviour of the curve
( like 1/4 of a circle, e.g.: http://www.schornsteinmarkt.de/images/p … 2016_0.jpg )
I thought about something like, point A (start of the arc) and point B (end of the arc) and maybe a controlpoint C (on the curve/arc) are given and the curve/arc will be drawn through the points.
Maybe someone can help me with a hint or tip to do this.
Thanks in advance.
