Jacques,
The "Save Window as" command does not change any map/layer properties. By this I mean that no matter what options you choose (size, resolution, etc.), the map layer properties (including text size) will never change. The option to use a custom size acts the same as if you had changed the size of the window. One very good way of seeing what "Save Window as" will produce is to create a layout with the map in question in a frame. Change the frame size to the intended custom size and you will see the same labels and relationship of graphic objects (symbols, line styles) to geography that you will see in the exported bitmap.
If your intention was to create an image that graphically scales (text and symbols get larger or smaller based on the frame size), the best way to do that is to save an image without changing the size but at a higher resolution, assuming the image is meant to get larger. The behavior will be slightly different based on your format choice.
By choosing EMF, you are creating a vector format where the text and symbols are described at some base size. The rendering engine in Windows for EMF will display the image in a new size and will effectively call the font renderer with different size fonts as you change the viewing size.
In the case of PNG, the output is raster. By saving with a higher resolution, the display is not changing the font size but scaling the raster. The closer one gets to a 1 to 1 pixel to display size, the better the image will look.
If your requirement is to be more flexible about the eventual display size, EMF is probably a safer choice. This is the scenario that a vector export was designed to handle. However, if the goal is to send the image to someone else, fonts (such as the MapInfo symbol fonts and any text fonts you use) would have to exist on the end users system for the EMF to display with those fonts. A PNG, being already rasterized, does not have this issue.
Since you mentioned Visio, you would have to check what Visio does with imported metafiles as well. However, most of the Microsoft Office related products handle metafiles well.
I hope this helps.
Sincerely,

| Subject: | [MI-L] MI 7 Window export |
Testing the possibilities of vector format (png and emf) for insertion of a mapper window “saved as “ into a Visio document, I have noticed that label size do not seem to follow window size redefinition before saving. That is, if I multiply by two the size of the window to be saved, label text is not increased proportionately. Do other versions than MI 7.0 have the same problem? Or am I way down left field passed the parking lot?
