Description:
------------
Hi,

I am trying to draw 4 dashed lines between some pictures. 

The following attributes I am using (calculating) (pls see source code below)

371+22, 20+55, 425+(425/2), 300, 1
434+22, 20+55, 425+(425/2), 300, 1
308+22, 20+55, 425+(425/2), 300, 1
497+22, 20+55, 425+(425/2), 300, 1



Reproduce code:
---------------
$bgImg = imageCreate(850, 400);
ImageColorAllocate ($bgImg, 55, 77, 134);

$logo_server = "./images/logo_server.png";
imageCopyMerge($bgImg, $dist_server, $start_pic, 75, 0, 0, 43, 55, 100);
[...]
// merging all pictrues (of the servers) in $bmImg

imagedashedline($bgImg, 393, 75, 425+(425/2), 300, 1);
imagedashedline($bgImg, 456, 75, 425+(425/2), 300, 1);
imagedashedline($bgImg, 330, 75, 425+(425/2), 300, 1);
imagedashedline($bgImg, 519, 75, 425+(425/2), 300, 1);

Expected result:
----------------
However only 2 lines are drawn. When I try imageline (instead of imagedashedline), I get all 4 lines.

I am not quite sure why this happens. Perhaps because the x2-coord is a decimal ...???

any ideas?

kind regards
thomas

The function expects integers to be passed.

already tried this....
same effect with:

imagedashedline($bgImg, 393, 75, 638, 300, 1);
imagedashedline($bgImg, 456, 75, 638, 300, 1);
imagedashedline($bgImg, 330, 75, 638, 300, 1);
imagedashedline($bgImg, 519, 75, 638, 300, 1);
