Using negative margins to zoom in on map

[Brian Maring]

I am using negative margin values to zoom in on my map. I would like to do the following:

 

I have a 300 by 400 map. I would like to remove 25% off the right hand side, 20% off the left hand side, 10% off the top, and 5% off the bottom. What should I set the margins to? Can you give me a detailed example of these calculations?

Hi,

 

 

 

For a map showing 300x400 with 25% left off from right and 20% off from left, 10% off from top and 5% off from bottom

 

 

 

please try:

 

 

 

mapRightMargin='136'

 

mapLeftMargin='109'

 

mapTopMargin='24'

 

mapBottomMargin='47'

 

 

 

Calculation: the zoomed view width inside 300 pixel window is 100-(25+20) = 55%. The virtual map 100% width is 545.

 

 

 

If 55% = 300, 25% = 136 , 20% = 109

 

 

 

the zoomed view height inside 400 pixel window is 100-(10+5) = 85%. The virtual map 100% height is 470.

 

 

 

If 85% = 400, 10% = 47 , 5% = 24
