Hello,
on the wiki, here
http://sumo.dlr.de/wiki/SUMO-GUI#Showing_Background_Images, it is stated
that background images "should have in both directions (height and
width) a size which is equal to 2^x.".
I am wondering: is this also and still the case in NETEDIT (version
0.32.0)? I am asking because it also states SUMO-GUI may load .bmp and
.gif files, but I've had good results using .png files.
A thing I have noticed when using background images: after setting the
name of the file to be used (I typically put the .png file in the same
place as the .net.xml file, and then enter just the file name of the
image, without the path), I have to close and re-open the network in
NETEDIT for the image to be displayed. Is this normal, or am I doing
something wrong?
Another thing: it would be great to be able to edit the image within
NETEDIT, ie. have a bounding box, and drag the image, and set it's size,
preferably while maintaining aspect ratio. Is this a feature that is
planned for a future release? As it is now, I have to calculate the
pixels per meter, and then the actual size the picture represents by
hand. Moving the picture to a location after the network has been
(partly) drawn is also somewhat tricky. Being able to edit those
attributes within the network UI would be very handy.
Thanks, greets!
Menno
