Change colour of stamp content on placement...

[lidds]

Firstly I would like to say that I love the new ability to convert annotation elements to a stamp using the createStampFromSel option. I do however have a question, I have developed a stamp designer for my end users to allow them to draw annotation elements e.g. lines, circles, text etc. and then convert these into a stamp. What I was wondering is if it would be possible to change the colour of the annotation elements when the user places the stamp from the stamp palette e.g.

1. Draw the stamp using PDFXchange annotation elements only, and for this example lets assume the designer placed all annotation elements using black colour
2. Select the annotation elements and create a stamp using the createStampFromSel option. The stamp is now placed in the stamp palette.
3. The user now opens a PDF document and wants to place the newly create stamp on the document. This obviously all works fine. However lets assume the user wants to place the stamp but as Red instead of Black. Is there anyway that I could somehow interrupt the stamp placement event, and somehow save the stamp pdf document to the local machine, change the colour of the annotation elements to Red, and then place this newly changed colour stamp?

I hope that makes sense, just unsure where to start with this.

Thanks

Hello Simon,

I believe you have already asked a similar question here:

Alex,

Thanks for reminding me, I have tried the following but it does not seem to change the colour of the stamp annotation elements. It does however add new text in the correct colour, this is done as a test.

I guess I have to loop through each annotation element in the stamp, which I am trying to do, but with no joy. I guess I am actually going down the wrong route, would you be able to help.

Note: The IPXC_Annotation variable being passed in the sub is that of the stamp.

Code: Select all

Public Sub changeStampColour(pxsInst As IPXS_Inst, ByRef annot As IPXC_Annotation)
        Dim stampAnnotType As UInteger = pxsInst.StrToAtom("Stamp")
        If annot.Type <> stampAnnotType Then
            Return
        End If
        Dim objApp As Object = annot.Handler.GetAppearance(annot, Nothing)
        Dim varApp As IPXS_PDFVariant = DirectCast(objApp, IPXS_PDFVariant)
        If varApp Is Nothing Then
            Return
        End If
        Dim xForm As IPXC_XForm = annot.Page.Document.GetXForm(varApp)
        If xForm Is Nothing Then
            Return
        End If
        Dim content As IPXC_Content = xForm.GetContent(PXC_ContentAccessMode.CAccessMode_WeakClone)
        Dim cc As IPXC_ContentCreator = annot.Page.Document.CreateContentCreator()
        cc.Attach(content)

        Dim color As PDFXEdit.IColor = auxInst.CreateColor(PDFXEdit.ColorType.ColorType_RGB)
        color.Value = "rgbd(" & MISData.Instance.frmMain.activeAnnoColour.R.ToString & "," & MISData.Instance.frmMain.activeAnnoColour.G.ToString & "," & MISData.Instance.frmMain.activeAnnoColour.B.ToString & ")"
        cc.SetStrokeColorRGB(color.RGB)
        cc.SetColorRGB(color.RGB)

        Dim contentList As IPXC_ContentItems = content.Items

        For i As UInteger = 0 To contentList.Count
            Dim item As IPXC_ContentItem = contentList.Item(i)
            Dim annotElement As PDFXEdit.IPXC_Annotation = TryCast(contentList.Item(i), PDFXEdit.IPXC_Annotation)
            Console.WriteLine(annotElement.Type.ToString)
        Next

        Dim fnt As PDFXEdit.IPXC_Font = Me.docPreview.Doc.CoreDoc.CreateNewFont2("ArialMT")
        cc.SetFont(fnt)
        cc.SetFontSize(10.0F)
        Dim rc As PXC_Rect = xForm.BBox
        cc.ShowTextLine(rc.left + 5, rc.bottom + 25, MISData.Instance.FirstName & " " & MISData.Instance.LastName)
        cc.ShowTextLine(rc.left + 5, rc.bottom + 15, Now.ToShortDateString & " " & Now.ToShortTimeString)

        xForm.SetContent(cc.Detach())
    End Sub

Thanks in advance

Hello Simon,

Well the Annotations are not a part of the Content and are definitely not a Content Items. Simply speaking, they are being flattened before they become a part of the Stamps Content and you cannot distinguish them afterwards. You can change the colors of the content items though but you will have to know for yourself which items should be changed or not and that is not a simple task.

Cheers,
Alex

Thanks Alex for getting back to me.

Is it possible to change the colour of all content items regardless?

Thanks

Simon

Hello Simon,

Yes, it can be done, though the method to change the IPXC_Color has an awkward translation to the .Net as it uses a pointer to the array. We've added a new method, though it will be available in the upcoming release. Please bump this thread when the new release is out and I will give you the sample on how to do this.

Cheers,
Alex

Alex,

I don't suppose you have an estimated time on this release? As always my clients are on my case to try and get this feature added to my software.

Thanks for your help

Hello Simon,

It should be out in a week or so.

Cheers,

Alex,

Do you have an ETA on this new release with this functionality?

Thanks

Hello Simon,

Build 325 was released earlier this week.
You can get it from here:
https://www.pdf-xchange.com/product/downloads/dev

Alex,

Thanks for letting me know. However when I log into my account is says I have the most recent version 7.0.324.2

I guess I won't need an upgrade license key and can just use my one from version 7.0.324.2 and download from your previous link?

Thanks

Simon

Hi Simon,

Yes - if you have current maintenance plan - you can use the key you already have with the latest installed from the downloads page.

Regards,
Stefan

Thanks Alex,

Just out of interest is there any chance of getting that sample code to change the colour of stamp elements on placement?

Thanks

Hello Simon,

Here's the sample that I promised:

Code: Select all

public void ModifyCState(ref IPXC_Content content)
{
	for (uint i = 0; i < content.Items.Count; i++)
	{
		IPXC_ContentItem item = content.Items.GetItemForEditing(i);
		if (item.Type == PXC_CIType.CIT_XForm)
		{
			IPXC_XForm xf = content.Document.GetXFormByHandle(item.XForm_Handle);
			IPXC_Content cnt = xf.GetContent(PXC_ContentAccessMode.CAccessMode_WeakClone);
			ModifyCState(ref cnt);
			xf.SetContent(cnt);
		}
		else if (item.Type == PXC_CIType.CIT_Path)
		{
			PDFXEdit.IColor color = auxInst.CreateColor(PDFXEdit.ColorType.ColorType_RGB);
			color.SetRGB(0.0f, 1.0f, 1.0f);
			IPXC_CState cstate = item.GetCState();
			IPXC_Color fill = cstate.FillColor;
			//fill.SetIColor(color);
			//cstate.FillColor = fill;
			IPXC_Color stroke = cstate.StrokeColor;
			//stroke.SetIColor(color);
			double[] rgb = new double[3] { 1.0, 0.0, 1.0 };
			stroke.SetComponents2(rgb);
			cstate.StrokeColor = stroke;
			item.SetCState(cstate);
		}
				
	}
}

public void ModifyStampOnPlacement(IPXS_Inst pxsInst, ref IPXC_Annotation annot)
{
	uint stampAnnotType = pxsInst.StrToAtom("Stamp");
	if (annot.Type != stampAnnotType)
		return;
	object objApp = annot.Handler.GetAppearance(annot, null);
	IPXS_PDFVariant varApp = (IPXS_PDFVariant)objApp;
	if (varApp == null)
		return;
	IPXC_XForm xForm = annot.Page.Document.GetXForm(varApp);
	if (xForm == null)
		return;
	IPXC_Content content = xForm.GetContent(PXC_ContentAccessMode.CAccessMode_WeakClone);
	IPXC_ContentCreator cc = annot.Page.Document.CreateContentCreator();
	cc.Attach(content);
	cc.ResetAllStatesToDefault();

	ModifyCState(ref content);

	PDFXEdit.IColor color = auxInst.CreateColor(PDFXEdit.ColorType.ColorType_RGB);
	color.SetRGB(0.0f, 1.0f, 1.0f);

	cc.SetFontSize(14.0f);
			
	color.SetRGB(0.0f, 0.0f, 1.0f);
	cc.SetFillColorRGB(color.RGB);
	color.SetRGB(1.0f, 0.0f, 0.0f);
	cc.SetStrokeColorRGB(color.RGB);
	PDFXEdit.IPXC_Font fnt = pdfCtl.Doc.CoreDoc.CreateNewFont2("ArialMT");
	cc.SetFont(fnt);
	PXC_Rect rc = xForm.get_BBox();
	cc.ShowTextLine(rc.left + 10, rc.bottom + 20, "TestLine");
	xForm.SetContent(cc.Detach());
}

Cheers,
Alex

Alex,

Thank you so much, the code works perfectly.

Thanks

Alex,

I have just noticed that placing the stamp and changing the colour works fine. However if I add a comment to the stamp, then this is shown in it's original stamp colour, is there a way to change this as well?

Thanks

Simon

Hello Simon,

Should be the same as modifying the stamp itself - in the add annotation operation.
You can get the reply parent with this property:

Then you can modify it and it's popup as you want:
