Copy window area of PDF and paste...

[lidds]

What I want to do is allow the user to be able to define a rectangle on a PDF document, like your crop tool, and then be able to copy and paste this onto an existing blank PDF page. Is something like this achivable? And if so how?

Thanks in advance

Hello Simon,

Would Snapshot tool work for you?

Alex,

I have tried the snapshot tool, however I am unable to paste this onto an existing blank PDF document. Tried right click and paste but the snapshot image is not pasted?

Hello Simon,

Alex,

I need to release my software on Wednesday, so can't really wait.

I do however have another idea, is it possible to add a clip region to an existing document and then export the clipped region to a new pdf file and then add white space around the clipped region, so that the user has some white space to add annotation to?

Thanks

Hello Simon,

Probably the snapshot tool will work for you in some case. The snapshot tool itself is an selection.pageRect type selection. Basically you can catch it with the e.docSelection.changed event and casting the parameters to the IPXV_PageRectSelection interface:

Code: Select all

else if (e.nEventID == nIDS[(int)IDS.e_docSelection_changed])
{
				
	PDFXEdit.IPXV_Document Doc = (PDFXEdit.IPXV_Document)e.pFrom;
	uint nLen = e.pEvent.Param2;
	var buffer = new int[nLen];
	IntPtr ptr = new IntPtr(e.pEvent.Param1);
	if ((ptr != null) && (nLen != 0))
	{
		Marshal.Copy(ptr, buffer, 0, (int)nLen);
		for (uint i = 0; i < nLen; i++)
		{
			IPXV_DocSelection docSel = Doc.GetSelCluster(buffer[i]);
			IPXV_PageRectSelection prs = docSel as IPXV_PageRectSelection;

The you can get the PageRect property out of it and use it to export the content items that are in that rectangle.

Cheers,
Alex
