PdfProcessing: Provide API for inserting Table of Contents (TOC)

This could be implemented by linking to RadFixedPages or Bookmarks.

Until this feature is developed this could be custom created with the help of Link annotations:

RadFixedPage toc = new RadFixedPage();
document1.Pages.Insert(0, toc);

FixedContentEditor editor = new FixedContentEditor(toc);

foreach (RadFixedPage page in document1.Pages)
{
	int pageNumber = document1.Pages.IndexOf(page);

	if (pageNumber > 0)
	{
		int factor = 20;

		int offsetX = 70;
		int offsetY = 20 + factor * pageNumber;
		editor.Position.Translate(offsetX, offsetY);

		Block block = new Block();
		block.GraphicProperties.FillColor = new RgbColor(255, 5, 99, 193);
		block.InsertText($"Page {pageNumber}");
		Size blockSize = block.Measure();
		editor.DrawBlock(block);

		Location location = new Location
		{
			Left = 0,
			Top = 0,
			Zoom = 0,
			Page = page
		};

		GoToAction goToAction = new GoToAction();
		goToAction.Destination = location;

		Link uriLink = toc.Annotations.AddLink(goToAction);
		uriLink.Rect = new Rect(offsetX, offsetY, blockSize.Width, blockSize.Height);
	}
}

public void CreateIndex()
{
PdfFormatProvider provider = new PdfFormatProvider();
PdfImportSettings importSettings = new PdfImportSettings
{
CopyStream = true
};

provider.ImportSettings = importSettings;
var inputSteam = File.OpenRead("D:\\DPS\\Bundling - V3\\TestFile\\out\\out.pdf");
RadFixedDocument document1 = provider.Import(inputSteam);

using (Stream output = File.OpenWrite("D:\\DPS\\Bundling - V3\\TestFile\\out\\out12.pdf"))
{
RadFixedPage toc = new RadFixedPage();
document1.Pages.Insert(0, toc);
FixedContentEditor editor = new FixedContentEditor(toc);

foreach (RadFixedPage page in document1.Pages)
{
int pageNumber = document1.Pages.IndexOf(page);

if (pageNumber > 0)
{
int factor = 20;

int offsetX = 70;
int offsetY = 20 + factor * pageNumber;
editor.Position.Translate(offsetX, offsetY);

Block block = new Block();
block.GraphicProperties.FillColor = new RgbColor(255, 5, 99, 193);
block.InsertText($"Page {pageNumber}");
Size blockSize = block.Measure();
editor.DrawBlock(block);

Location location = new Location
{
Left = 110,
Top = 110,
Zoom = 10,
Page = page
};

GoToAction goToAction = new GoToAction();
goToAction.Destination = location;

Link uriLink = toc.Annotations.AddLink(goToAction);
uriLink.Rect = new Rect(offsetX, offsetY, blockSize.Width, blockSize.Height);
}

provider.Export(document1, output);
}
}

seems to be Rect not visible in doc, please check below my sample code.

 

public void CreateIndex()
{
PdfFormatProvider provider = new PdfFormatProvider();
PdfImportSettings importSettings = new PdfImportSettings
{
CopyStream = true
};

provider.ImportSettings = importSettings;
var inputSteam = File.OpenRead("D:\\DPS\\Bundling - V3\\TestFile\\out\\out.pdf");
RadFixedDocument document1 = provider.Import(inputSteam);

using (Stream output = File.OpenWrite("D:\\DPS\\Bundling - V3\\TestFile\\out\\out12.pdf"))
{
RadFixedPage toc = new RadFixedPage();
FixedContentEditor editor = new FixedContentEditor(toc);

foreach (RadFixedPage page in document1.Pages)
{
int pageNumber = document1.Pages.IndexOf(page);

if (pageNumber > 0)
{
int factor = 20;

int offsetX = 70;
int offsetY = 20 + factor * pageNumber;
editor.Position.Translate(offsetX, offsetY);

Block block = new Block();
block.GraphicProperties.FillColor = new RgbColor(255, 5, 99, 193);
block.InsertText($"Page {pageNumber}");
Size blockSize = block.Measure();
editor.DrawBlock(block);

Location location = new Location
{
Left = 110,
Top = 110,
Zoom = 10,
Page = page
};

GoToAction goToAction = new GoToAction();
goToAction.Destination = location;

Link uriLink = toc.Annotations.AddLink(goToAction);
uriLink.Rect = new Rect(offsetX, offsetY, blockSize.Width, blockSize.Height);
}

provider.Export(document1, output);
}
}
}
