TImageEnProc.GetReSel

Declaration

function GetReSel(out SelX1, SelY1, SelX2, SelY2: Integer; var mask: TIEMask): Boolean; overload;
function GetReSel(out SelX1, SelY1, SelX2, SelY2: Integer; var PolySel: PPointArray; var PolySelCount: Integer; var mask: TIEMask): Boolean; overload;

Description

Return the selected area of the attached TImageEnView or SelectedRect. Returns False if there isn't a selected area.

If a TImageEnView is not attached and Selected = False, it returns the full rect of the bitmap (Result = False).
If TImageEnView.Selected is True, Result is True. Bounds come from TImageEnView.SelectionMask when it is non-empty; otherwise from SelX1..SelY2 (vectorized / in-progress selection can leave the mask empty). Degenerate empty-mask bounds fall back to the full image. Callers that require a raster mask should also check Assigned(Mask) and not Mask.IsEmpty.

Note:
◼This method is the same as accessing TImageEnView.SelectionMask, but returns more information
◼The pixels of SelX2, SelY2 are excluded from processing, e.g. if an entire 100x100 image is selected, SelX1, SelY1, SelX2, SelY2 will 0,0,100,100
