I want to create a table in a PDF document which would have variable width of columns depending on the width of its contents.
I am using PDFSharp, MigraDoc
Maybe getting the paragraph width from the individual cells will help. Is there a way to get text width depending on the font / styles?
Any clues?
Thanks.
Using PDFsharp functions, you can get the width of any text.
MigraDoc is not limited to PDF, it creates documents for PDF, RTF, print. No chance to determine the exact width (unless you restrict yourself to PDF and use PDFsharp to get the width).
MigraDoc will break text in columns to the next line when needed.
Create a dummy PdfDocument, create a page, get an XGraphics object (gfx) for that page, then use gfx.MeasureString() to find the width.

Is there any way I can convert the contents of a rich text box to a bitmap in WPF?
I tried the solution mentioned in the following post: Saving RichTextBox FlowDocument to image
But my dilemma is I am unable to figure out how to calculate the required size of the bitmap before hand that would cover the entire flow document.
Please help. Thanks in advance.
FlowDocuments don't have a rigid size, that's the point:
Flow Document Overview:
Flow documents are designed to optimize viewing and readability. Rather than being set to one predefined layout, flow documents dynamically adjust and reflow their content based on run-time variables such as window size, device resolution, and optional user preferences.
You need to set either a height or a width restraint, or both. If you set only one, width for example, the FlowDocument will update to stretch vertically until all the content has been displayed. After you set the constraint(s), you can check the actual size of the document and that will give you the required size of your image.
I have working iTextsharp code for printing labels. Now the problem is, I have a requirement to print the labels in Continuous paper which i am not able to select in iTextsharp configuration (iTextSharp.text.PageSize.A4). Please advice how can i select the page size according to my current scenario.
Thanks
Your problem is related to PDF as a document format. In PDF, the content is distributed over different pages. You can define the size of such a page yourself. You mention iTextSharp.text.PageSize.A4, but you can define the page size as a Rectangle object yourself. See iTextsharp landscape document
If you want a long, narrow page, you could define the page size like this:
Document Doc = new Document(new Rectangle(595f, 14400f));
There are some implementation limits though. The maximum height or width of a page is 14,400 user units. See the blog post Help, I only see blank pages in my PDF!
However, I am pretty sure that you don't want to create a long narrow page. If you want to print labels on "continuous paper", you want to create a PDF document in which every page has the size of exactly one label. Your PDF will have as many pages as there are labels.
Suppose that the size of one label is 5 by 2 inch (width: 12.7cm; height: 5.08cm), then you should create a document like this:
Document Doc = new Document(new Rectangle(360, 144));
And you should make sure that all the content of a label fits on a single page. Your label printer should know that each page in the PDF should be printed on a separate label.

I am working on creating a report with MigraDoc that would be able to have table with 2 columns divided in the same page. It's possible with any settings of Table object?

MigraDoc cannot do that on its own.
You can get a PDF with such a table if you create a MigraDoc document with just 50% page width (and the height of your page body) and then use PDFsharp to draw two pages from the MigraDoc document onto one page of the final PDF.
This sample draws 9 large pages as thumbnails on one page and cane be used to get started:

I want to add Bookmark in my PDF using MigraDoc.
For example: two images on a single page.
1. Images1
2. Images2**
and the same name bookmark will generate.
If I click on image1 bookmark that image will be shown to me. Remember both images are on single page.
MigraDoc creates bookmarks automatically for headings.
To create bookmarks without visible text on the page, you can create headings with a font size of e.g. 0.0001 and white colour.
There is one drawback: up to PDFsharp 1.50 beta 1, these bookmarks jump to the correct page, but not the correct area on the page. So with two images on one page, the bookmarks will not work as intended by the OP.
I'm writing a web application to generate labels. The label printer that I'm targeting utilizes 12mm tape and the customer specified that they want to limit the labels to 3.25". I know that with iTextSharp I can specify the size of the document I want to create, however it appears that I have to specify both a width and height.
Document document = new Document(new iTextSharp.text.Rectangle(234f, 33.84f));
234 is 3.25" converted to points, and 33.84 is 12mm converted to points, so this sets the document to the maximum size allowed. Is there any way to set just the height and let the document auto-expand to the amount of content? With that, is there a way to determine if the expanded width of the document exceeds to maximum allowed by the customer? Thanks in advance for any help you can offer.
No, that is not possible in iText. It's not a particularly good idea anywhere else either. As Redman said, PDF is a print-based format. It's not HTML.
There are some tricks you can do to get around this to some extent:
Create your page with the maximum legal height. 200" * 72dpi = 14400 points.
Add a "generic tag" to your paragraphs.
create a tag event handler that tracks where the bottom of your last paragraph was drawn.
Save the PDF.
Open it again with a PDFStamper
Set the bottom of the page to match the location of that last paragraph. Remember that the bottom left starts off at 0,0, and the top right will be
Save the final PDF
This trick will only work if your total output is less that 200" high. If you go over that, you'll still get a second page, and your "where the bottom is" code had better be prepared for it.
PS: I don't see what's wrong with having a number of 12mm x 3.25" pages... won't that perfectly fit the labels they want printed?
As far as I know, because PDF is a print format, the document width and height must be set.
This is why reporting tools generally default page sizes to the default printer page size.
You best bet to try and calculate the size of the content and create the PDF accordingly.
Depending on the volume and nature of the workflow, you could provide a preview for the customer to check before printing.
