I'm trying to set the page width and height to 4x6 in PDFsharp from C#. I'm using the following:
page.Width = "4in";
page.Height = "6in";
Still defaults a 8X11 page.
The following code worked for me:
PdfPage page = document.AddPage();
page.Width = "4in";
page.Height = "6in";
Using
pdfPage.Width = XUnit.FromInch(4);
pdfPage.Height = XUnit.FromInch(6);
is better because it avoids string parsing at runtime, but the string version is also working.
Was able to locate the answer to this here is the code to format the page to 4X6 inches:
pdfPage.Width = XUnit.FromInch(4);
pdfPage.Height = XUnit.FromInch(6);

Is it possible to scale a page from e.g. A2 to A1 with PDFsharp?
I can set the size of the page via Size, Width and Height. But how can I scale the content of the page?
based on the comment from Vive and the link provided there, here an example for resizing to A4 with C#:
you must include:
using PdfSharp.Pdf;
using PdfSharp.Drawing;
using PdfSharp;
then:
// resize this file from A3 to A4
string filename = #"C:\temp\A3.pdf";
// Create the new output document (A4)
PdfDocument outputDocument = new PdfDocument();
outputDocument.PageLayout = PdfPageLayout.SinglePage;
XGraphics gfx;
XRect box;
// Open the file to resize
XPdfForm form = XPdfForm.FromFile(filename);
// Add a new page to the output document
PdfPage page = outputDocument.AddPage();
if (form.PixelWidth > form.PixelHeight)
page.Orientation = PageOrientation.Landscape;
else
page.Orientation = PageOrientation.Portrait;
double width = page.Width;
double height = page.Height;
gfx = XGraphics.FromPdfPage(page);
box = new XRect(0, 0, width, height);
gfx.DrawImage(form, box);
// Save the document...
string newfilename = #"c:\temp\resized.pdf";
outputDocument.Save(newfilename);
You can use DrawImage() to draw an existing PDF page on a new PDF page. You can specify the destination rectangle and thus you can scale the page as needed.
Use the XPdfForm class to access the existing PDF file.

I have generated some PDF report using MigraDoc. Initial code is as follows:-
MigraDoc.DocumentObjectModel.Document document = new MigraDoc.DocumentObjectModel.Document();
MigraDoc.DocumentObjectModel.Section section = document.AddSection();
...
Paragraph paragraph = section.Headers.Primary.AddParagraph();
....
table = section.AddTable();
...
paragraph = section.Footers.Primary.AddParagraph();
...
The PDF was rendered successfully. Now I want to add some graphics into the pages of this document. I have gone through several articles for that and found that everyone using PdfDocument class instead of MigraDoc.DocumentObjectModel.Document. Is it possible to apply graphics into pages of a document of type MigraDoc.DocumentObjectModel.Document using XGraphics? If it is not possible, what is the best way to mix PdfDocument with MigraDoc.DocumentObjectModel.Document to accomplish the same?
MigraDoc uses PDFsharp and an XGraphics object to create the PDF pages.
There are several ways to add content to pages created by MigraDoc.
This MigraDoc sample shows some options:
http://pdfsharp.net/wiki/MixMigraDocAndPdfSharp-sample.ashx
You can even call MigraDoc to use "your" XGraphics object for drawing:
// Alternative rendering with progress indicator.
// Set a callback for phase 1.
pdfRenderer.DocumentRenderer.PrepareDocumentProgress += PrepareDocumentProgress;
// Now start phase 1: Preparing pages (i.e. calculate the layout).
pdfRenderer.PrepareRenderPages();
// Now phase 2: create the PDF pages.
Console.WriteLine("\r\nRendering document ...");
int pages = pdfRenderer.DocumentRenderer.FormattedDocument.PageCount;
for (int i = 1; i <= pages; ++i)
{
var page = pdfRenderer.PdfDocument.AddPage();
Console.Write("\rRendering page " + i + "/" + pages);
PageInfo pageInfo = pdfRenderer.DocumentRenderer.FormattedDocument.GetPageInfo(i);
page.Width = pageInfo.Width;
page.Height = pageInfo.Height;
page.Orientation = pageInfo.Orientation;
using (XGraphics gfx = XGraphics.FromPdfPage(page))
{
gfx.MUH = pdfRenderer.Unicode ? PdfFontEncoding.Unicode : PdfFontEncoding.WinAnsi;
gfx.MFEH = pdfRenderer.FontEmbedding;
pdfRenderer.DocumentRenderer.RenderPage(gfx, i);
}
}
Console.WriteLine("\r\nSaving document ...");

I need to use this plugin to add watermarks to images using classic ASP. I had this work partially using this code:
dim o, b, wm, layer,textlayer
Set b = CreateObject("ImageResizer.Configuration.Config")
Set wm = CreateObject("ImageResizer.Plugins.Watermark.WatermarkPlugin")
Set textlayer = CreateObject("ImageResizer.Plugins.Watermark.TextLayer")
Set layer = CreateObject("ImageResizer.Plugins.Watermark.Layer")
textlayer.Text = "Yeees"
textlayer.fontSize = 50
layer.fill = True
set layer("dd") = textlayer 'THIS IS FAILING
wm.NamedWatermarks("sfdf") = layer("dd") 'THIS IS FAILING TOO
wm.Install(b)
b.BuildImage "C:\lg1_1361_44.jpg", "C:\lg1_1361_44_WATER.png", "watermark=tessst&format=png"
Why are you creating an instance of Layer? TextLayer and ImageLayer are the classes you want to work with
I would drop everything related to 'layer' and try this instead.
textLayer.fill = True
wm.NamedWatermarks("sfdf") = textLayer
You'll also need "watermark=sfdf" instead of "tessst"
I have a self defined web control.
Some code in a loop:
double cellHeight = 12.34;
Label dcell = new Label();
dcell.Style["height"] = cellHeight + "pt";
dcell.Text = cellHeight;
If I use CultureInfo("cs-CZ")
System.Threading.Thread.CurrentThread.CurrentCulture = new CultureInfo("cs-CZ");
System.Threading.Thread.CurrentThread.CurrentUICulture = new CultureInfo("cs-CZ");
after render, the html came out
<span style="height:11,75pt">11,75</span>
actually what I expected is:
<span style="height:11.75pt">11,75</span>
height:11,75pt is totally wrong when rendered in browser, actually the browser does not consider 11,75pt as 11.75pt.
However I need to keep the text field displayed based on culture info: the text field displays 11,75 that is correct.
So this is the problem - how can I fix?
You need to convert double to string properly, for example:
dcell.Style["height"] = cellHeight.ToString("F", CultureInfo.CreateSpecificCulture("eu-ES")) + "pt";
Or like this:
NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = ".";
dcell.Style["height"] = cellHeight.ToString(nfi) + "pt";
I have written a imageHandler.ashx in c# which draw image of a text on a fly . Its takes a parameter string txt. The Handler is called from Asp.net page. At the time of calling, if text contains the character # or any special character .it Does not create the images of #,or any special character's given to it.
According to my R&D the problem is with a Graphics.DrawString() method some how its is unable to write special characters.so please tell me how to create a image of a special characters
Code I am using :
String signatureText = HttpUtility.HtmlDecode(signatureText);
System.Drawing.Text.PrivateFontCollection fontCollection = new System.Drawing.Text.PrivateFontCollection();
FontFamily ff1 = fontCollection.Families[0];
// Initialize graphics
RectangleF rectF = new RectangleF(0, 0, imgWidth, imgHeight);
Bitmap pic = new Bitmap((int) rectF.Width,imgHeight, PixelFormat.Format24bppRgb);
Graphics g = Graphics.FromImage(pic);
//g.SmoothingMode = SmoothingMode.Default;
// g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAlias;
g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
Font font1 = new Font(ff1, imgHeight, FontStyle.Regular, GraphicsUnit.Pixel);
float bestFontSize = BestFontSize(g, new Size(imgWidth, imgHeight), font1, signatureText);
Font font2 = new Font(ff1, bestFontSize, FontStyle.Regular, GraphicsUnit.Pixel);
// Set colors
Color fontColor = Color.Black;
Color rectColor = Color.White;
SolidBrush fgBrush = new SolidBrush(fontColor);
SolidBrush bgBrush = new SolidBrush(rectColor);
// Rectangle or ellipse?
g.FillRectangle(bgBrush, rectF);
// Set font direction & alignment
StringFormat format = new StringFormat();
//format.FormatFlags = StringFormatFlags.DirectionRightToLeft;
format.Alignment = StringAlignment.Center;
format.LineAlignment = StringAlignment.Center;
// Finally, draw the font
g.DrawString(signatureText, font2, fgBrush, rectF, format);
pic = (Bitmap) ImageUtility.ResizeImageWithAspectRatio(pic, imgWidth, imgHeight, true);
pic.Save(context.Response.OutputStream, System.Drawing.Imaging.ImageFormat.Jpeg);
Any help is Appreciated Thanks in Advance
DrawString() don't have any problem while writing special characters if they are provided in font file (.ttf)
Problem can be in the following line
System.Drawing.Text.PrivateFontCollection fontCollection = new System.Drawing.Text.PrivateFontCollection();
Specially with the font you get in ff1
FontFamily ff1 = fontCollection.Families[0];
In your case it means Font ff1 don't have representation for some or all special characters.
Since I don't know how many font files you are getting from fontCollection.Families, if fontCollection.Families contain more than one font file try next one.
FontFamily ff1 = fontCollection.Families[1]; // and so on.
Or try to add font file with all special characters (if System.Drawing.Text.PrivateFontCollection is absolutely necessary ).
Alternatively you can use InstalledFontCollection instead of PrivateFontCollection
System.Drawing.Text.InstalledFontCollection fontCollection = new System.Drawing.Text.InstalledFontCollection();
Which will give you all installed fonts of the system on which application is running through its Families property InstalledFontCollection.
Easiest way is (if only one font is required, as you are using only one font in your provided code)
using constructor of FontFamily class with a string type parameter FontFamily.
Consider replacing this line
FontFamily ff1 = fontCollection.Families[0];
With this one
FontFamily fontFamily1 = new FontFamily("Arial");
Arial must be installed on the system where application is running.
Hope this will help.
DrawString doesn't have any problem with drawing special characters like # or copyright (I just tested it and produced the image below).
The problem might be from your URL parameter. Try encoding your text using Server.UrlEncode when passing the text, and then Server.UrlDecode before giving it to DrawString.
