just had a thought which may be werth pursuing if you're desperate for exact relative dimensions in MI.
there are API's available which will control the size of an application. if you figger out how much of the application window a maximized map takes up, you can use the API to modify the size of the MI application to suit... with some system metrics and twips-per-pixel calculations. anywho, just a brainfart. -----Original Message----- From: Simmonds, Ashley (DTUP) [mailto:[EMAIL PROTECTED] Sent: Thursday, 29 July 2004 12:38 PM To: [EMAIL PROTECTED] Subject: RE: MI-L MB: Save Window command ah yes, the relative dimensions of the output image will be based on the size of the map window. one way to get it exact is to keep altering the size of the map window and using the save window as command to see what size it currently is, and messing around until it's the size you want. i don't believe there's a command to change the size of the window itself. that said, i fergot this is an issue as my app with integrated mapping (in access) has a pixel-perfect resize command, so before saving a window i can specify exact sizes for the map... so far i've tried up to around 4000 pixels without a major hassle. i'm not sure that this functionality is transferable to MI due to MI being within a strictly controlled placeholder on an access form. does anyone know of a method of exactly sizing a map window? -----Original Message----- From: SCISOFT [mailto:[EMAIL PROTECTED] Sent: Wednesday, 28 July 2004 5:46 PM To: 'Jaromir Svasta'; [EMAIL PROTECTED] Subject: RE: MI-L MB: Save Window command Sorry, that should be ".. the W is as expected (10 inches x 96 dots per inch) but the H should be 750 pixels, not 720.
