Streamlining Chunk Addition in ColumnText Without Storing All in JVM about openpdf HOT 5 OPEN

Yes, it is possible to add phrases individually. However, besides memory issues, I need the content to be at a specific position (positionX and positionY) within a specified width. Can you please guide me on whether it is possible to achieve this with a direct paragraph or phrase?

Ah, ok, then ColumnText indeed should be used.

Unfortunately I'm not into such layout processing details. Maybe someone else can help.

I'm wondering about the starting issue, that you encountered OutOfMemoryException when using phrase/paragraph directly and decided to use ColumnText to handle the text chunk by chunk. Unless you put all the content into a single element (like a single paragraph or table containing all the content), adding phrases/paragraphs directly should not require more memory than using ColumnText, at least not a relevant amount.

Hi @mkl-public,

Thank you.

I'm still wondering what are you really trying to achieve. We have here a parser. We read a template and parse it, producing the PDF on the way. So content is added as a stream to the PDF. On the way titles, paragraphs, list and so on are created.

Do you have some kind of draft, how your document should look like?

Hello @asturio,

Assume my goal is to generate a multi-colored e-book with complex formatting, including:

• Multiple headings
• Paragraphs
• Bullet point text
• Inline links
• Highlighted text
• Various colors and fonts
• Images
  etc.,

The content is extensive, potentially exceeding 1000 pages, and comes from multiple data sources. Due to the large volume, holding all the content in the JVM is not possible. Therefore, I am looking for a way to write the content chunk by chunk.

Additionally, I need the ability to place content at specific positions (positionX and positionY) within a specified width, and I may require multiple columns of text in the PDF.
