Is there a way to print a Skia Graphic to Printer on Windows?
I'm evaluating Ski as a replacement for Cairo. In Cairo on Windows we can directly print  to a Printer HDC

Direct printer call will work soon for Windows and MacOS

@Fritzew It is worth mentioning that currently prints already work normally with Skia4Delphi Canvas enabled, but internally the native Canvas of FMX is used during prints. In addition, it is possible to export the document via PDF and XPS.

I'm testing it at Moment with VCL, so a FMX Canvas is out

Another Question: How thread save is SKIA?   We prepare a lot oaf Drawing-Layers in Threads and put it together after finished. Works well with Cairo.
 

At Moment I check first the Speed of Drawings to decide if it is worth to switch

Good question. The title page states 

Quote

1. Canvas for UI (created from a window eg rectangles, circles, objects inherited from TControl) must draw exclusively from the main thread, while Canvas created from TBitmap are thread safe.

but that's listed under FMX. Does it apply to VCL as well?

The library can be divided into 3 independent parts:

• Api: Console, FMX and Vcl;
• Controls and integration with TBitmap: FMX and Vcl;
• Skia4Delphi Canvas: FMX.

 

Skia4Delphi Canvas is an option that, when enabled, the entire application will be rendered by our engine, be it a TButton, a TCircle, the form itself... The benefits of this are: speed, quality and new features. This feature was only made for the FMX because the Vcl system is too restricted for it.

Its text was taken from the part of Skia4Delphi Canvas (FMX). It is just clarifying that it is not necessary to adapt any code, the operation will continue the same as an FMX application without the library.

 

Remembering that the integration with TBitmap (using TBitmap.SkiaDraw) is not related to the Skia4Delphi Canvas feature, they are independent integrations. It will always work on both Vcl and FMX, and is also safe to use on both main and background threads (just like TBitmap).

Hi all,

I'm having problem with the onClick event of a TSkSvg component: it simply does not fire :-(

Same with a TSkAnimatedImage; same with the mouseDown / Up events...

 

TSkLabel's onClick works well, on the contrary; the OnWordClick is perfect, too :-)

 

is it me? does it work for you? This is a showStopper for me...

Thanks in advance!

Ciao

Hi @b1ol, the default HitTest of TSkSvg and TSkAnimatedImage is False. So, you need to set the property HitTest to True to use the mouse operations.

Hi @vfbb, thanks a lot!

Yes, you're right, this is a FMX thing, I' should have checked... shame on me!!! ;-)

Thanks again for this help and for the great work you're doing with Skia4delphi

Have a nice day
