I am having problems deciphering the limited notes
in the api.
style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">I am hoping someone can give
me a suggestion to find out more about MapGuide plotting using the API
(onEndLayout).
style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">
style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">I have not been able to find
somebody who uses plain old MapGuide to plot files on D or E size layouts.
The usual suggestion is use LiteView. I created an app that allows the
user to select which image they want on the output, which size (D or E) and
which rotation (portrait or Landscape).

style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">
size=2>Based on what I have
read in the limited api documentation, setting of the extents (ext) is a
function of where on the output the image will be, measure in
pixels.

style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">

and error, this equals about 315pixels per inch.

working until they tried some random scales and rotations that created totally
inconsistent results.
style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">THIS SHOULD NOT BE SUCH A
HASSLE! The image placement appears to be random depending on rotation and
scale selections.
