Hello Aaron,
the problem is that the api documentation not differing exactly when the developer should use screen coordinates or page coordinates. I try the same example which i have send you with converting page coordinates before selecting text:
var page = _viewer.GetDoc().GetPage(_viewer.CurrentPageNumber);
var cropBox = page.GetCropBox();
double x1 = cropBox.x1;
double y1 = cropBox.y1;
_viewer.ConvPagePtToScreenPt(ref x1,ref y1,_viewer.CurrentPageNumber);
double x2 = cropBox.x2;
double y2 = cropBox.y2;
_viewer.ConvPagePtToScreenPt(ref x2,ref y2,_viewer.CurrentPageNumber);
var selected = _viewer.Select(x1, y1, x2, y2);
But then nothing is selected. I try the select method with screen coordinates and with page coordinates and also the following code
var selected = _viewer.Select(cropBox.x1, cropBox.y1, _viewer.CurrentPageNumber, cropBox.x2, cropBox.y2, _viewer.CurrentPageNumber);
What i want is to select the text from a page which i have set not from all page or other it should be the page "I" want! So i hope you can help!
Best Regards
Daniel
