将imagesetthickness（）过滤到PHP中的特定行

Question

The imagesetthickness() on the PHP will change the thickness of all lines on the image. Is there any way to select what line to be associated with this function? For Example in following image I would like to ONLY change the thickness of GREEN lines to 5.

<?php
 $image = ImageCreate(130, 170);
 $white = ImageColorAllocate($image, 255, 255, 255);
 $black = ImageColorAllocate($image, 0, 0, 0);
 $green = ImageColorAllocate($image, 82, 128, 8);

 ImageFill($image, 0, 0, $white);

 ImageSetThickness ($image , 5);

 ImageLine($image,60,40,60,100,$black);
 ImageLine($image,25,25,100,25,$green);

 ImagePng($image, "flag.png");
 ImageDestroy($image);
 ?>

Answer 1

You just need to set the thickness to the desired value before calling imageline .

<?php
 $image = ImageCreate(130, 170);
 $white = ImageColorAllocate($image, 255, 255, 255);
 $black = ImageColorAllocate($image, 0, 0, 0);
 $green = ImageColorAllocate($image, 82, 128, 8);

 ImageFill($image, 0, 0, $white);

 // set to 3 for the next call 
 ImageSetThickness ($image , 3);
 ImageLine($image,60,40,60,100,$black);

 // set to 5 for the next call
 ImageSetThickness ($image , 5);
 ImageLine($image,25,25,100,25,$green);

 // Set back to 3 for any future calls calls
 ImageSetThickness ($image , 3);

 ImagePng($image, "flag.png");
 ImageDestroy($image);
