wrap text when line is too long

[lbr991]

I'm using insert_text but the text is too long and it exceeds the page's width, how can I wrap the text? Is there an alternative to having to calculate the wrapping cutoff myself and adding +n pixels to y (for the next line)?

You can use page.insert_textbox() instead. If you want to be lazy, choose a large text box like this: rect = page.rect + (36, 36, -36, -36). This will leave a 1/2 inch margin (= 36 points). Linebreaks will happen automatically. The statement looks like page.insert_textbox(rect, text, ...).

I get 2 blank pages now, this is the debugging output:

[JorjMcKie]

You do not check the return code of rc = page.insert_textbox(). If the text does not fit in the rectangle then rc < 0, and the method is a no-op.
