how to render a long text in an area with automatic wrap

[artex]

Hello everyone,
with php I create this command for image composition that works. But I want to render the text in a box area of a width of 100px (es.).
Does anyone know tell me the parameters to give the text?

if I use-size parameter again for text area doesn't work

convert -size "500"x"500" xc:white -density "72"x"72" -units PixelsPerInch -draw "translate 0,0 image Over 0,0 425,425 "background.jpg"" -draw "translate 155,100 image Over 0,0 125,125 "image/sun.jpg"" -font "font_ttf/font_ttf/Helvetica.ttf" -pointsize "16" -fill "red" -draw "translate 130,240 text 0,0 'text i like wrap in a box area of 150px large!'" out.png

it is very urgent!

"-draw text" doesn't word-wrap. "caption:" does. See http://www.imagemagick.org/Usage/text/

try

Code: Select all

convert -background none -size 150x -fill black -font yourfont -pointsize PP caption:"your text here" result.png

Then composite this over your background image at the desired locations using -gravity and -geometry

Code: Select all

convert backgroundimage result.png -gravity ZZ -geometry +X+Y -compose over -composite finalresultimage

my I use -size parameter two time?

After your indication i have tried:

convert -size "500"x"500" xc:white -density "72"x"72" -units PixelsPerInch -draw "translate 0,0 image Over 0,0 425,425 "background.jpg"" -draw "translate 155,100 image Over 0,0 125,125 "image/sun.jpg"" -font "font_ttf/font_ttf/Helvetica.ttf" -pointsize "16" -fill "red" -draw "translate 130,240 -size 150x caption: 'text i like wrap in a box area of 150px large!'" out.png

but does'nt works.

but does'nt works.

I am not surprised; I would work on one step at a time and when that works move onto the next - you have so many things going on it would be very hard to debug.

You will also need to use parenthesis to group certain options.

It would be a good idea to link to an expected final output image so we know what you actually want.

But I start by a comand that works:

convert -size "500"x"500" xc:white -density "72"x"72" -units PixelsPerInch -draw "translate 0,0 image Over 0,0 425,425 "background.jpg"" -draw "translate 155,100 image Over 0,0 125,125 "image/sun.jpg"" -font "font_ttf/font_ttf/Helvetica.ttf" -pointsize "16" -fill "red" -draw "translate 130,240 text 0,0 'text i like wrap in a box area of 150px large!'" out.png

do you kow how insert caption parameter with -size in my comand?

(I have seen parenthesis link)

thanks

You need to learn to use parenthesis processing so that the arguments do not apply repeatedly to the wrong part of the code. Also break long commands into newlines using a trailing \ at the end of the section so that the code is readable. See http://www.imagemagick.org/Usage/basics/#parenthesis.

-draw does not word wrap. you need to use caption and -size=Wx (not -size=WxH). See http://www.imagemagick.org/Usage/text/

[snibgo]

-draw "translate 130,240 -size 150x caption: 'text i like wrap in a box area of 150px large!'"

The syntax is wrong. "caption:" is not a valid option for "-draw".
