Trying to make motivational posters with ImageMagick

[benito]

Hello!

My image skills are very limited with ImageMagick. Im trying to create a motivational poster like this one:



After a few steps i managed to get this result starting with a white rectangle image.



I use this code to make that:

Code: Select all

<?php
 shell_exec('convert source.jpg  -bordercolor 000000 -border 3x3 step1.jpg');
 shell_exec('convert step1.jpg  -bordercolor white -border 2x2 step2.jpg');
 shell_exec('convert step2.jpg  -bordercolor 000000 -border 10%x10% step3.jpg');
?>

Now im stuck with the last steps.

1. Extend the black border at bottom.
2. Place the Two lines of text, centered and if its possible autosized.

What commands i need to make this?

Thanks

You could check out my example on this page http://www.rubblewebs.co.uk/imagemagick ... border.jpg as it may save you some steps.

Also every time you save an image as a jpg you are getting some jpg compression, use png or other lossless format and save to jpg last !

Thanks Bonzo

Now i managed to make this result:



Now i need to know how to separate the texts and if its possible how to auto size the font.

This is the code i use

Code: Select all

<?php
	exec('convert source.jpg  -bordercolor 000000 -border 3x3 step1.ppm'); // add small black border
	exec('convert step1.ppm  -bordercolor white -border 2x2 step2.ppm'); // add white line around the image
	exec('convert step2.ppm  -bordercolor 000000 -border 10%x10% step3.ppm'); //add a wide black border around

	exec("convert step3.ppm -size 15x15 xc:black -background black -append -font 'roman.ttf' -pointsize 64 -fill white -draw \"gravity South text 0,0 'SOME TITLE'\" text1.ppm");
    exec("convert text1.ppm -size 15x15 xc:black -background black -append -font 'roman.ttf' -pointsize 32 -fill white -draw \"gravity South text 0,0 'MORE TEXT MORE TEXT MORE TEXT MORE TEXT '\" step4.jpg");
?>

This is the sort of thing you can do and so have less tempory images to deal with ( 3 different ways to do the same thing):

Your original code cleaned up a bit.

Code: Select all

<?php
   exec('convert source.jpg  -bordercolor black -border 3x3 step1.ppm'); // add small black border
   exec('convert step1.ppm  -bordercolor white -border 2x2 step2.ppm'); // add white line around the image
   exec('convert step2.ppm  -bordercolor black -border 10%x10% step3.ppm'); //add a wide black border around

   exec("convert step3.ppm -font 'roman.ttf' -pointsize 64 -fill white -draw \"gravity South text 0,0 'SOME TITLE'\" -pointsize 32 -fill white -draw \"gravity South text 0,-20 'MORE TEXT MORE TEXT MORE TEXT MORE TEXT '\" step4.jpg");
?>

<img src="step4.jpg">

Read the image in and resize it and add the borders; create a black background and put the image onto it.  Write the text directly to the first image.
<?php
exec("convert \( source.jpg -resize 250x250 -bordercolor black -border 3x3 -bordercolor white -border 2x2 \) -size 300x400 xc:black -gravity north -geometry +0+30 +swap -composite border.png"); 

exec("convert border.png -pointsize 32 -fill white -draw \"gravity South text 0,60 'SOME TITLE'\" -pointsize 16 -gravity south -annotate +0+30 \"MORE TEXT MORE TEXT\\nMORE TEXT MORE TEXT \" text.png");
?> 
<img src="text.png">

Read the image in and resize it and add the borders; create a black background and put the image onto it.  Write the text to another image then paste the text onto the first image.
<?php
exec("convert \( source.jpg -resize 250x250 -bordercolor black -border 3x3 -bordercolor white -border 2x2 \) -size 300x400 xc:black -gravity north -geometry +0+30 +swap -composite border.png");

exec("convert \( -size 300x100 -background black -font verdana.ttf -fill white -gravity North caption:\"The quick red fox jumped over the lazy brown dog.\" -flatten \) border.png -gravity south +swap -composite  caption1.jpg");
?>  

The only thing is you would need to use something like getimagesize and and use the values in your code e.g replace -size 300x400 with -size {$width}x{$height}
