Absolute positioning of text (iText 7)

I want to put a check mark using Zapfdingbats on a specific location in my PDF document. What I achieved so far is this: I can show the check mark but it's on the side of the document and not on the specific X, Y coordinate that I want it to be.
I'm dealing with a situation where I have a Phrase added to a ColumnText object. The title in black is where iText is placing the text of the Phrase within the ColumnText . The title in pink is the desired placement. Is there anything I can do to tell iText not to put any space between the top of the highest glyphs (D and Z in this case) and the top of the ColumnText box?
I am currently creating the document by creating ColumnText objects that are placed at specific coordinates. The content consists of variable data (text/barcodes/images) that is added to existing PDF documents/templates (think boiler plate). Most commonly, I have to place various sections of text in specific places.
Plenty of lines in my code look awfully redundant and in my opinion, this can't be the cleanest way to do things. Unfortunately, I can't figure out how to create a separate function to which I can simply pass some parameters, such as string , x_Cord , y_Cord , tilt .
I'm trying to get some rows of text on the left side and some on the right side. For some reason iText seems to ignore the alignment entirely.
I have a web site where the users upload photos and create photo books. Also, they can add text at absolute positions, rotations, and alignments. The text can have new lines. How do I rotate such text that consists of multiple lines?
I want to use ColumnText to wrap text in a rectangle, but I get a DocumentException .
I'm converting a document which is created with a online editor. I need to be able to rotate the text using it's central point and not (0,0).
I need to create an User guide, where I've to put the content in 2 different languages but on the same page. So the first half of the page would be in English while the second part would be in French.
I am getting the following error when I want to print a PDF generated with iTextSharp" "An error exists on this page. Acrobat may not display the page correctly. please contact the person who created the pdf document to correct the problem" The document prints fine, but why do I get this error?
