TImageEnProc.CanPasteFromClipboard

TImageEnProc.CanPasteFromClipboard


Declaration

function CanPasteFromClipboard(Dest: TIECopyPasteType = iecpAuto; InclImagesAsLayers: Boolean = True): Boolean;


Description

Returns true if the clipboard contains an image or an ImageEn layer that TImageEnProc can paste.
If Dest is iecpSelection then there must also be a valid selection in the associated TImageEnView.
InclImagesAsLayers has no effect unless Dest is iecpLayer. If true, the result will be true if the clipboard contains a layer or an image. If false, the result will be true only if there is a layer on the clipboard.

Notes:
- The Dest you specify for CanPasteFromClipboard, should be the same as the Dest for your call to CanPasteFromClipboard
- If the TImageEnProc is attached to a TIEBitmap, TImageEnMView or TImageEnFolderMView then only iecpFullImage is relevant (iecpAuto will have the same effect as iecpFullImage. iecpSelection and iecpLayer will always fail)
- This method supports PdfViewer if Source = iecpAuto


Examples

// Enable the Paste button if pasting is possible
btnPasteFromClip.Enabled := ImageEnView1.Proc.CanPasteFromClipboard();

// Paste only if there is a layer on the clipboard
if ImageEnView1.Proc.CanPasteFromClipboard( iecpLayer, False );
  ImageEnView1.Proc.PasteFromClipboard( iecpLayer );

// Paste a layer if there is an image or layer on the clipboard
if ImageEnView1.Proc.CanPasteFromClipboard( iecpLayer );
  ImageEnView1.Proc.PasteFromClipboard( iecpLayer );

// Append an image to a TImageEnMView from the clipboard
if IEMView1.Proc.CanPasteFromClipboard() then
begin
  IEMView1.AppendImage( 0, 0 );
  IEMView1.Proc.PasteFromClipboard();
end;
