Multiline strings

[4parsleythelion]

I love this library it's easy to use and understand, perfect. The only issue I'm running into currently is multiline strings e.g.

let text_source_address = "610 Monroe St.\nStoudsburg, PA 18630-2115";

The output from:

current_layer.use_text(text_source_address, 10, Mm(30.0), Mm(230.0), &font);

is:

610 Monroe St. Stoudsburg, PA 18630-2115

Ideas?

Thank you for your efforts

Use the add_line_break function:

let text_source_address = "610 Monroe St.\nStoudsburg, PA 18630-2115";

pdf_layer.begin_text_section();
pdf_layer.set_font(&font, 10);
pdf_layer.set_text_cursor(Mm(30.0), Mm(230.0));

for line in text_source_address.lines() {
    pdf_layer.write_text(line, &font);
    pdf_layer.add_line_break(); // <---
}

pdf_layer.end_text_section() // <- important!

If you take a look at the source code of use_text, it does just that:

Maybe I should add this to the use_text function.

Thank you for the reply, and it works with one little issue, all of the lines are on top of each other?

I assume that the set_text_cursor, sets the placement of the first text line, but the other lines get placed on top of the first so should I add a new text cursor with each line break?

Sorry to be a pain and thank you for your time in helping me out.

I think I forgot that you need to call set_line_height(10) first so that the PDF knows how much to advance. If that doesn't work, you have to calculate the (x, y) position of the line manually.

let text_source_address = "610 Monroe St.\nStoudsburg, PA 18630-2115";

pdf_layer.begin_text_section();
pdf_layer.set_font(&font, 10);
pdf_layer.set_text_cursor(Mm(30.0), Mm(230.0));
pdf_layer.set_line_height(10); // <- same as font size (or more, if you want more spacing)

for line in text_source_address.lines() {
    pdf_layer.write_text(line, &font);
    pdf_layer.add_line_break(); // <---
}

pdf_layer.end_text_section() // <- important!

EDIT: Yeah, I even added this to the documentation, lol:

Perfect, it works great.

Thank you for your time and effort, I'm a happy camper.
