Well looks like the rest of the day is going to be spent on this ... ;)
There's nothing I'd rather do than play with code. :D

It is certainly gratifying (excuse sarcasm) that the algorithm used by windows "sometimes" draws lines closer in appearance to the ones requested.
Rofl.

BTW testing your suggestion for wider lines certainly partly confirms what you said, but for something like an 8-pixel wide line, the rounded ends don't look very good.
Hmm, yes. It's only an approximation after all. |

| Right, well this whole thing has turned out more complex than I imagined.
It seems we need control over the line end and join styles, something we didn't have before.
I have added another bitmask to the pen styles (where the default is what it always did, which was have a round end).
The results are a bit more obvious with large line widths.
This is the code for a miter join:
local win = "win"
WindowCreate(win, 0, 0, 250, 150, miniwin.pos_center_all, 0, ColourNameToRGB "green")
WindowPolygon (win, "20,50,180,50,180,20,230,70,180,120,180,90,20,90",
ColourNameToRGB ("cyan"), -- pen colour
miniwin.pen_solid + miniwin.pen_join_miter, -- pen style
10, -- pen width
ColourNameToRGB("yellow"), -- brush colour
miniwin.brush_solid, -- brush style
true, -- fill
false) -- alternate fill
WindowShow(win, true)
Results:
Now changing the style line for a round join:
miniwin.pen_solid + miniwin.pen_join_round, -- pen style
Results:
And a bevel join:
miniwin.pen_solid + miniwin.pen_join_bevel, -- pen style
Results:

| | Slick! I didn't even realize that was possible. 4.59 will be a good release for miniwindows. |

| And now line endings:
local win = "win"
WindowCreate (win, 0, 0, 100, 100, miniwin.pos_center_all, 0, ColourNameToRGB "green")
WindowLine (win, 20 , 40 , 50 , 40 ,
ColourNameToRGB ("cyan"), -- pen colour
miniwin.pen_solid + miniwin.pen_endcap_flat, -- pen style
20) -- pen width
WindowShow (win, true)
miniwin.pen_solid + miniwin.pen_endcap_square, -- pen style
miniwin.pen_solid + miniwin.pen_endcap_round, -- pen style
The difference between square and flat is whether the pen width overshoots the dimensions of the line (the round overshoots as well).
This shot in Photoshop shows that:
The red box is the requested width, and you can see that the line overshoots on either side (square, however) by half the pen size. |
