Hi,<br>
<br>
I am working on a project in which I have to draw a large number of lines<br>
closed to each other.<br>
But it look too much dense. I want that when I zoomIn on lines then only<br>
other lines should be displayed.For ex. like in google map... Initially in<br>
Google map we saw thick picture but as we starts zoomIn steadily we see<br>
clear the other things like road,hotels etc.<br>
<br>
I have to add this ZoomIn functionality to my project.<br>
<br>
Is there any function in QGraphicsView or in QGraphicScence to achieve this<br>
or is this functionality already implemented in QGIS, if yes then please let<br>
me know where it is ? . I am using QPainter for drawing lines.<br>
<br>
Any help would greatly appreciated.<br>
<br>
Thanks<br>
Bargi<br>
