Hi,
The following draws two thick blue lines, one of length 1
and the other of length "len" using an image size of "size":
sl[len_,size_] :=
Show[ Graphics[ {RGBColor[0,0,1],Thickness[0.01],Line[{{0,0},{len,0}}],
Line[{{0,1},{1,1}}]}],ImageSize->size,AspectRatio->1/10]
On my machine:
sl[1/1000,450]
Shows a long thick line and
a very short thick line underneath it.
sl[1/1000,500]
Only the long line is visible, even tough the image is larger!
sl[1/1000,600]
The short line reappears.
The problem disappears when "Thickness[0.01]" is removed.
Do others have the same problem?
I would expect larger images to show more, and not less, details.
Also, it seems to me that thick lines should be visible whenever
thin lines are.
