Provide advanced graphical options under SWT #189

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Wishlist:
1. Line width
2. Transparency
3. Antialiasing

Although it is possible to add most of these options by subclassing, 
it would be nice to offer them out of the box.
For transparency, a change in PSWTGraphics2D (1.3) is necessary, though (bd1):

    public void setTransparency(float transparency) { // bd1
        gc.setAlpha((int) (transparency*255f));
    }

I have attached the classes ZPSWTCanvas and ZPSWTPath that add options for 
linewidth, transparency, and antialiasing

If these changes can be made without breaking binary compatibility, and I 
haven't fully reviewed them yet, then they can go into the 1.3.1 milestone.  If 
not, they will have to wait for 2.0.

In writing the example for Issue 187, I noticed that setStroke is missing and 
setStrokePaint is misnamed setStrokeColor.  Thought I should add those todos 
here.

On further review, these changes will have to wait for 2.0.  I will commit the 
patch plus changes refereed to in comment #2 to svn trunk.

Yes, I do.

Added transparency support similar to attached.

$ svn commit -m "Issue 189 ; adding transparency support for SWTGraphics2D and 
PSWTPath" swt swt-examples
Committed revision 1181.

Line width is there in SWTGraphics2D but PSWTPath doesn't take advantage of it. 
 Its PEN_WIDTH is always 1.0f.  More work would be required to implement that 
change properly.
