I want to show a logo and its description in a pdf using itextSharp.
Example:
Logo LogoDescription
My below code shows logo and its description on two different lines
Document^ doc = gcnew Document(iTextSharp::text::PageSize::LETTER,10,10,42,32);
doc->Open();
// add image
iTextSharp::text::Image^ bmp = iTextSharp::text::Image::GetInstance("bts_logo.bmp");
bmp->ScaleToFit(50,100);
bmp->Border = iTextSharp::text::Rectangle::BOX;
bmp->BorderColor = iTextSharp::text::BaseColor::RED;
bmp->BorderWidth = 2;
doc->Add(bmp);
doc->Add(gcnew Phrase("Logo description", gcnew iTextSharp::text::Font(iTextSharp::text::Font::FontFamily::HELVETICA, 11, iTextSharp::text::Font::BOLD)));
I am using Visual Studio 2012.
If you want to add a Phrase (e.g. a description) next to an Image (e.g. a picture), you typically create a PdfPTable:
PdfPTable table^ = gcnew PdfpTable(2);
This will create a table that shows borders by default. You can change this by adding this line:
table->DefaultCell->Border = iTextSharp::text::Rectangle::NO_BORDER;
You then add the image and the text as cells:
table->AddCell(bmp);
table->AddCell(phrase);
Where bmp is an instance of the Image class, and phrase is an instance of the Phrase class.
You then add the table to the document:
doc->Add(table);
The table will have borders by default, but as I am not familiar with the programming language you are using, you probably know better how to change the border of the default cell to NO_BORDER than I do.

I am trying to create a PDF using MigraDoc Library. I can add an image, but unable to rotate images. I am creating a MigraDoc.DocumentObjectModel.Shapes.Image object to add the image to a section. Is it possible to rotate the image or do I have to add the image another way?
Public Sub AddImageToPDFFile(sec As Section)
Dim image As Image
Dim strImagePath = "image.jpg"
image = sec.AddImage(strImagePath)
image.Height = "10cm"
image.LockAspectRatio = True
image.RelativeVertical = RelativeVertical.Line
image.RelativeHorizontal = RelativeHorizontal.Margin
image.Top = ShapePosition.Top
image.Left = ShapePosition.Left
image.WrapFormat.Style = WrapStyle.Through
End Sub
I'm afraid MigraDoc cannot rotate the image.
Maybe rotate the image with code before adding it to MigraDoc.
It might also be possible, depending on your requirements, to add the image later using PDFsharp. MigraDoc uses PDFsharp to create the PDF and thus you can use PDFsharp for modifications without adding an additional tool to the process.
I am using OxyPlot to export plots.
When I export them, I want to add a footer to these plots with information like the path it is saved, a time-stamp, and so on...
Right now I am doing this by creating an extra X-axis on a different position-tier and then setting the sizes of all ticks and labels to zero except for the title font-size.
This works, but as you might imagine, this is quite hacky and does not look that good (as you cannot set for example the aligning).
So my question is, is there a possibility to add such a footer to the exported plot?
EDIT:
var xAxis = new OxyPlot.Axes.LinearAxis
{
Position = AxisPosition.Bottom,
PositionTier = 1,
Title = "Footer: i.e. path to my file",
MinorTickSize = 0.0,
MajorTickSize = 0.0,
FontSize = 0.0,
TitleFontSize = 12,
AxisDistance = 10
};
This is the workaround I mentioned.
I create an axis at position-tier 1, which is below the first one and then disable all visuals of it except the title.
And in the end I add it to my plotmodel pm.Axes.Add(xAxis).
To export my plotmodel I use PdfExporter like this:
using (var stream = File.Create(testFile.pdf))
{
PdfExporter.Export(pm, stream, 800, 500);
}

Just had to do the same thing with my project and thought I'd share how I managed it for anyone else in need of a footer.
I couldn't find any built in OxyPlot methods to add a header or footer but if you use OxyPlot.PDF it's built on top of PDFSharp and you have more options to customize your PDF export.
Remove any previous reference to OxyPlot.Pdf in your project.
Download OxyPlot.Pdf source code from: https://github.com/oxyplot/oxyplot
In your project in VS, right click your solution in 'Solution Explorer' and Add Existing Project.
Navigate to the downloaded source code and add OxyPlot.Pdf.csproj
Right click your project and Add Reference
Select 'Projects' on the left and check the box for OxyPlot.Pdf on the right. Hit OK.
Check that it's working by building and running project.
Go to PdfRenderContext.cs file and find the PdfRenderContext method near the top.
Add the code below then build and run your project.
This code creates a MigraDoc Document and then merges it with the OxyPlot PdfDocument.
public PdfRenderContext(double width, double height, OxyColor background)
{
//*** Original Code - Don't change **//
this.RendersToScreen = false;
this.doc = new PdfDocument();
var page = new PdfPage { Width = new XUnit(width), Height = new XUnit(height) };
this.doc.AddPage(page);
this.g = XGraphics.FromPdfPage(page);
if (background.IsVisible())
{
this.g.DrawRectangle(ToBrush(background), 0, 0, width, height);
}
//*** New Code to add footer **//
Document myDoc = new Document();
Section mySection = myDoc.AddSection();
Paragraph footerParagraph = mySection.Footers.Primary.AddParagraph();
footerParagraph.AddText(DateTime.Now.ToShortDateString());
footerParagraph.Format.Alignment = ParagraphAlignment.Right;
MigraDoc.Rendering.DocumentRenderer docRenderer = new MigraDoc.Rendering.DocumentRenderer(myDoc);
docRenderer.PrepareDocument();
docRenderer.RenderObject(g, XUnit.FromInch(9.5), XUnit.FromInch(8), "1in", footerParagraph);
}
When you export the PDF a date stamp is now added to the lower right corner of the PDF. Note that I was working with landscape 8.5x11 inch paper so you may need to change position if you don't see it on the plot. Upper left corner is 0,0. Once it's working, build the OxyPlot.Pdf project to create the dll and then you can add it as a reference to your project and remove the source code.
Result:
I'm currently creating a PDF with PdfSharp which mostly consists of text and some images.
The text elements have different colors. My problem is that as soon as I use a different color than the color I started with, the text is not visible in the resulting PDF (e.g. I start with black text, switch to a red text, the red text is not visible). All text elements are in the resulting PDF (I can select them), but the red elements are invisible.
So here is the code:
// Create a new PDF document with one page
var document = new PdfDocument();
var page = document.AddPage();
page.Width = 800;
page.Height = 600;
var defaultFont = new XFont("Arial", 12, XFontStyle.Regular, new XPdfFontOptions(PdfFontEmbedding.Always));
var gfx = XGraphics.FromPdfPage(page);
// black text
gfx.DrawString("black", defaultFont, XBrushes.Black, new XRect(x, y, width, height), XStringFormats.Center);
// red text
gfx.DrawString("red", defaultFont, XBrushes.Red, new XRect(x2, y2, width2, height2), XStringFormats.Center);
I've already found a solution (re-creating the XGraphics object) but it's quiete messy because it needs to be called after each color change:
// ...
// black text
gfx.DrawString("black", defaultFont, XBrushes.Black, new XRect(x, y, width, height), XStringFormats.Center);
// disposing the old graphics context and creating a new one seems to help
gfx.Dispose();
gfx = XGraphics.FromPdfPage(page);
// red text
gfx.DrawString("red", defaultFont, XBrushes.Red, new XRect(x2, y2, width2, height2), XStringFormats.Center);
I guess there is a better solution, but I couldn't find one yet.
Edit
As suggested in this answer, I wanted to create a SSCCE. During the creation I found the actual bug. Instead of XBrushes.Red I used an own defined XBrush, but didn't mention it in the above code snippet, because I thought it was unnecessary.
As already mentioned in the last section of the question, I used an own defined brush instead of XBrushes.Red.
I defined it the following way:
XBrush redBrush = new XSolidBrush(new XColor {R = 207, G = 0, B = 44});
This way the brush only worked after I disposed the graphics object and created a new one. But after some googling I found the correct way to define a brush:
XBrush redBrush = new XSolidBrush(XColor.FromArgb(207, 0, 44));
I tried to replicate your problem using your code snippet and PDFsharp version 1.32. I used VS Express 2013 which automatically converted all projects to .NET 4.5.
I tried both builds (GDI+ and WPF) and all colours worked fine for me.
So instead of just a code snippet you should provide an SSCCE.

Hi guys I have an instance where I have a logo image as part of some artwork..
If a user uploads a new logo I have a form field which is larger than the default logo.
I then use that form field to position the new image.
The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo..
what I have done is:
foreach (var imageField in imageReplacements)
{
fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null);
fields.RegenerateField(imageField.Key);
PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber);
float[] logoArea = fields.GetFieldPositions(imageField.Key);
if (logoArea != null)
{
iTextSharp.text.Rectangle logoRect = new iTextSharp.text.Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]);
var logo = iTextSharp.text.Image.GetInstance(imageField.Value.Location);
if (logo.Width >= logoRect.Width || logo.Height >= logoRect.Height)
{
logo.ScaleToFit(logoRect.Width, logoRect.Height);
}
logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT;
logo.SetAbsolutePosition(logoRect.Left, logoArea[2] + (logoRect.Height - logo.ScaledHeight) / 2);
// left: logoArea[3] - logo.ScaledWidth + (logoRect.Width - logo.ScaledWidth) / 2
overContent.AddImage(logo);
}
}
The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine..
is there a way to set a stacking order on layers?
Annotations (such as form fields) are always on top of page contents. Annotation Z order is just the order of the annotations array on a given page.
Page content Z order is just the order everything appears in the content stream. New drawing operators go on top of proceeding operators.
If you want to cover your old image, draw a white box over it and then draw the new logo over top that. No need to worry about annotations.
Actually, all you really need to do is not set the background color of the imageField. You're already scaling the new logo to match the size of the old one.
However, if you really must draw that white box, it's fairly simple:
overContent.setColorFill(iTextSharp.text.Color.WHITE);
overContent.rectangle( logoRect );
overcontent.fill();
I pieced together some code to insert a dynamic image into a PDF using both ColdFusion and iText, while filling in some form fields as well. After I got it working and blogged about it, I couldn't help but think that there might be a better way to accomplish this. I'm using the basic idea of this in a production app right now so any comments or suggestion would be most welcomed.

I have made it in another way with itext library
I don´t want overwrite my existing pdf with the image to insert, so just modify the original pdf inserting the image, just insert with itext doesn´t work for me.
So, I have to insert the image into a blank pdf (http://itextpdf.com/examples/iia.php?id=59)
And then join my original pdf and the new pdf-image. Obtaining one pdf with several pages.
(http://itextpdf.com/examples/iia.php?id=110)
After that you can overlay the pdf pages with this cool concept
