I am generating a PDF that populates the PDFFormFields with the values inputted by the user in a Sharepoint 2010 WebPart, like so:
PdfPCell cellPaymentAmountTextBox = new PdfPCell()
{
CellEvent = new DynamicTextbox("textBoxPaymentAmount"),
Phrase = new Phrase(boxPaymentAmount.Text, timesRoman9Font)
};
tblFirstRow.AddCell(cellPaymentAmountTextBox);
("boxPaymentAmount" is a Textbox control on the WebPart)
It's working pretty well, except that the values inputted appear gray instead of black on the PDF file:
How can I get these to be black instead of gray?
I am using a font that is declared as black, not gray:
Font timesRoman9Font = FontFactory.GetFont(FontFactory.TIMES_ROMAN, 9, BaseColor.BLACK);

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'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.

I have a PDF where I add some TextFields.
var txtFld = new TextField(stamper.Writer, new Rectangle(cRightX - cWidthX, cTopY3, cRightX, cTopY), FieldNameProtocol) { Font = bf, FontSize = cHeaderFontSize, Alignment = Element.ALIGN_RIGHT, Options = PdfFormField.FF_MULTILINE };
stamper.AddAnnotation(txtFld.GetTextField(), 1);
The ‘bf’ above is a Unicode font that gets embedded in the PDF:
BaseFont bf = BaseFont.CreateFont(UnicodeFontPath, BaseFont.IDENTITY_H, BaseFont.EMBEDDED); // Create a Unicode font to write in Greek...
Later-on I fill those fields with greek text.
var acrof = stamper.AcroFields;
acrof.SetField(fieldName, field.Value/*, field.Value*/); // Set the text of the form field.
acrof.SetFieldProperty(fieldName, "setfflags", PdfFormField.FF_READ_ONLY, null); // Make it readonly.
When I view the PDF, most of the times the text is missing and if I click on the (invisible) TextField in Acrobat, then the text becomes visible (until it loses focus again).
Any idea what is going on here?
I have also tried using non-embedded font, but I get the same thing (although I still seem to get embedded fonts in PDF that are similar to the font I use). I don't know if I am missing sth.
It seemed that I was doing the following at the wrong order (the following is the correct):
acrof.SetFieldProperty(field.Name, "setfflags", PdfFormField.FF_READ_ONLY, null); // Make it readonly.
acrof.SetFieldProperty(field.Name, "textfont", bf, null);
acrof.SetField(field.Name, field.Value/*, field.Value*/); // Set the text of the form field.
At least that's hat I think it was wrong.
I have made many changes.
How to change color of hyperlink after clicking on hyperlink (visited state).
I create hyperlink dynamically with next code:
I use Paragraph into RichTextBox in XAML
I fill this TShortName object in code behind with:
TShortName.Inlines.Add(GetNameUrlAsLink(((MyClass)DataContext).MyProperty));
And finally I populate data (hyperlink) with:
private Hyperlink GetNameUrlAsLink(string hp)
{
var hl = new Hyperlink
{
NavigateUri = new Uri(hp),
TargetName = "_blank",
Foreground = new SolidColorBrush(currentAccentColorHex),
FontSize = 20,
};
hl.Inlines.Add(hp);
return hl;
}
As a result, I get hyperlink with accent color (currentAccentColorHex). But I need to change that color when I click on link because it becomes white which is not appropriate for me at all.
Best regards
try this
Dim scb As New SolidColorBrush()
scb.Color = Colors.Green
myHyperlinkButton.Background = scb
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();
