Question

How to create patterns like these:

From a single image in PHP with GD?

I’ve tried a lot but I think it can be done easier.

My thoughts:
Fill with imagefilledrectangle for one line. For the second line fill it with a margin left and right (for my first example). Next cut the image in two pieces and fill the margins with it and repeat this for each line.

I hope someone can help me out 🙂

Thanks!

Sorry for my late respons, meanwhile I’ve used Imagick for this, with the follow effects:

<?php
$output_h   = 500;
$output_w   = 500;
$image_size = 100;
$src    = 'input.jpg';
$output = 'output.jpg';

//Centering
exec('convert '.$src.' -resize '.$image_size.' -background white -gravity center -extent '.$output_w.'x'.$output_h.' '.$outfile);

//Mirror
exec('convert '.$src.' -resize '.$image_size.' \( -clone 0 -flip \) -append -write mpr:sometile +delete -size '.$output_w.'x'.$output_h.' tile:mpr:sometile '.$outfile);

//Half drop vertical
exec('convert '.$src.' -resize '.$image_size.' -format "%[fx:round(h/2)]" info:',$result);
exec('convert '.$src.' -resize '.$image_size.' \( -clone 0 -roll +0+'.$result[0].' \) +append -write mpr:sometile +delete -size '.$output_w.'x'.$output_h.' tile:mpr:sometile '.$outfile);

//Half drop horizontal
exec('convert '.$src.' -resize '.$image_size.' -format "%[fx:round(w/2)]" info:',$result);
exec('convert '.$src.' -resize '.$image_size.' \( -clone 0 -roll -'.$result[0].'-0 \) -append -write mpr:sometile +delete -size '.$output_w.'x'.$output_h.' tile:mpr:sometile '.$outfile);

//Fill
exec('convert '.$src.' -resize '.$image_size.' +append -write mpr:sometile +delete -size '.$output_w.'x'.$output_h.' tile:mpr:sometile '.$outfile);
?>
