It IS posible to "delete" pixels from an image in PHP natively - the key-function is imageAlphaBlending: <?php $image = imageCreateTrueColor(101, 101); imageSaveAlpha($image, true); # draw a red cycle with alpha blending $red = imageColorAllocateAlpha($image, 255, 0, 0, 30); imageFilledEllipse($image, 50, 50, 100, 100, $red); # disable alpha blending for deletion imageAlphaBlending($image, false); # paint with a complete opaque color $trans = imageColorAllocateAlpha($image, 0, 0, 0, 127); # you can clear every shape you like imageFilledRectangle($image, 30, 30, 70, 70, $trans); # enable alpha blending again imageAlphaBlending($image, true); # draw a green rectangle with alpha blending $green = imageColorAllocateAlpha($image, 0, 255, 0, 40); imageFilledRectangle($image, 40, 20, 90, 80, $green); header("Content-Type: image/png"); imagePNG($image); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 138.246.7.187 ---- Manual Page -- http://www.php.net/manual/en/function.imagesetpixel.php Edit -- https://master.php.net/note/edit/97776 Del: integrated -- https://master.php.net/note/delete/97776/integrated Del: useless -- https://master.php.net/note/delete/97776/useless Del: bad code -- https://master.php.net/note/delete/97776/bad+code Del: spam -- https://master.php.net/note/delete/97776/spam Del: non-english -- https://master.php.net/note/delete/97776/non-english Del: in docs -- https://master.php.net/note/delete/97776/in+docs Del: other reasons-- https://master.php.net/note/delete/97776 Reject -- https://master.php.net/note/reject/97776 Search -- https://master.php.net/manage/user-notes.php
