dynamic size for pictures

Oct 29, 2015 at 7:33 AM
For visualisation I created 6 different categories of shapecategories (being used in a point shapefile). Now I want the size of the picture to depend on a variable, is that possible? I've seen something for gradientfill, but that's for colors.

Of course I can devide every category into 10 others for 10 different sizes, but I don't think that's the best way to do it. The result should be 60 shapecategories....

Anybody ideas?

When looking at the categories class (http://www.mapwindow.org/documentation/mapwingis4.9/class_shapefile_categories.html) I see a reference to a sample http://www.mapwindow.org/documentation/mapwingis4.9/_point_icons_8cs-example.html
In this sample an image is set to the DrawingOptions of a category. When I go to the Shapefile drawing options (http://www.mapwindow.org/documentation/mapwingis4.9/class_shape_drawing_options.html) I see a PictureScaleX and Y (http://www.mapwindow.org/documentation/mapwingis4.9/class_shape_drawing_options.html#a67b574c8e73d9d09ec70955843306895).
Perhaps you can use that? I I haven't tried myself.

Let me know if it works or not.

Thanks for your reply.

I was looking for a way to manipulate the size of a picture direct when putting them in the shapefile. Working with categories I think we need a matrix of categories wich will cause much more categories. Is that correct?
