itext7

问题 I'm trying to get this c# function from within a asp.netcore razor project using itext7 (7.1.7) to output a div containing text that scales up to within the constraints given with height and width. However, for some reason it seems there's some kind of hidden margin that will not scale the text to the boundaries of the given width and height, even though the margins are set to 0.

问题 I am using iText to recreate the Tag Tree feature of Acrobat. So far I have managed to get the tag structure. The final thing I am trying to figure out is how to get & decode the "Marked Content" for a tag from the content stream.

Edit 2 : Add iText RUPS reference Below image shows where I have reached in the tree, the red line points to a MCID, I am trying

问题 I am trying to use iText 7.1.1 to convert a TIFF image to PDF file with multiple pages. Thanks for those to get me started with this article Create PDF from TIFF image using iText. However, it is iText 5.5.x and I have trouble to duplicate it in iText 7. I did find TiffImageData.getNumberOfPages(raf) to replace int pages = TiffImage.getNumberOfPages(rafa) . However, I am not able to replace TiffImage.getTiffImage(rafa, i) in iText7. Do I need to use new Image(ImageDataFactory.createTiff(...))

问题 I am parsing a PDF document using itext7. I have fetched all the form fields from the document using AcroForm, but I am unable to get font associated with the field using GetFont method. I also tried to parse /DA dictionary but it returns as a PDFString. Is there any way around to get font information or I have to parse /DA dictionary 回答1: Actually iText 7 does have a method to determine form field font information, it's needed for generating form field appearances after all: PdfFormField

问题 I can´t believe, what I see.... I try to print a table with itext7 into a PDF on a defined page. The table-creation is made as last statement before finishing the PDF. The PDF has (after finishing) 5 pages. I can print the table to every page except the first page. This is my code: If placeOnPage = 0 Then table.SetFixedPosition(200, 250, 100) Else table.SetFixedPosition(placeOnPage, 200, 250, 100) End If If placeOnPage = 0, then the table is printed correctly on the last page. If I set
