5 Error parsing images in HTML files - ID: 1819614

Last Update: Comment added ( psoares33 )

Details:

I am currently using the iTextSharp port to generate HTML to PDF and have
found a slight bug and have one suggestion....

When progressing images in HTML the SAX parser checks if the stack contains
a section, chapter or cell. In most cases this is invalid as images will be
inside P's or DIV's and therefore can I recommend you include Paragraphs in
this or statement (SAXiTextHanderl.java - line 502

On a related note, if the image url is relative i.e "/image/test" an
exception is thrown as the file is recognised. Would it be wise to prefix
urls beginning with "/" with the current application directory (or html
file path root). I have done so in my itextsharp build but perhaps it
should be an option

Date: 2008-05-30 07:22 Sender: nobody Logged In: NO I got the same problem when my html-markup contains images in div-tags. The problem is method AddImage in ITextHandler. In this case the program runs through the else branch. I'didd't understand why, but there a new stack is built by moving the items from the main stack (stack) to the new stack (newstack). The error occurs because the while-loop is exited by an exception because the loop contains executing though stack.Count = 0 because the element we are searching for is never found. Because of this the items will never be moved back to the main stack and all further stack.Pop()-statements will fail. I changed the while condition to "!(current is Chapter \|\| current is Section \|\| current is Cell) && stack.Count!=0" but maybe someone who knows the code better should check this.

I changed the while condition to "!(current is Chapter || current is
Section || current is Cell) && stack.Count!=0"
but maybe someone who knows the code better should check this.
