problem with new line (\n) in textWrap

anneMurielle

Hi,

I don't know if I'm doing something wrong but I'm not able to display the new line with the textWrap when I load the text from a txt file. The \n is displayed as a normal text. Did I miss something ? If I put the text directly in the code it works. Here is my code:

local file = io.open("text/"..pageNumber..".txt", "r")
local str = file:read("*all")
file:close()

local text = TextWrap.new(str, width, "left", 20, conf.textFont)
text:setPosition(x,y)
self:addChild(text)

Thank you a lot for you help!

@anneMurielle do you have \n directly in your text or there are new lines which are converted to \n by TextWrap?

anneMurielle

Hi, the \n are directly in the text contains in the text file. Do I need convert them ?

@anneMurielle yes it seems it escapes them this way, so most probably you should have real new lines in the text file and not the \n symbols itself

Seems to work thank you

A new question, is there a way to lighten the background of the text ? I mean, I've some background images for the ebook and sometime the text is difficult to read (if the color are too dark...). Is it possible to lighten only the place behind the text ? Or should I directly modify the background image ?

No way to directly change, but, well, theoretically, you could always draw the Shape object with needed fill color around the textwrap object, by getting textwrap width and height

I've done that, thank you à lot for your help!
