I am using MapWinGIS map control to display photos, and each photo has lat/long record.
Now I want to display the background JPEG image of the point shapefile( points from the photo lat/long data), which corresponds to it. And when I click the small Thumbnail， I can get bigger or full size image.
How can I display the JPEG inside shapefile with georeferencing, which will automatically display JPEG?
like the following
And how to set the PictureScaleX ??
the code does not work
var ct = sf_photo.Categories.Add(“Photo”);
var opt = ct.DrawingOptions;
opt.PointType = tkPointSymbolType.ptSymbolPicture;
opt.Picture = pointImage;
opt.Picture.LoadBuffer(50);
opt.PictureScaleX =0.001; // does not work????? what value can do work?
opt.PictureScaleY =0.001;
The picture(pointImage) size is very big in the mapcontrol
