dsaba Posted February 27, 2006 Share Posted February 27, 2006 below is the script i'm having trouble with, all it does for now is crop just one image and then displays it, I would like to manipulate it so I can have it crop hundreds of images by linking to a directory or to a database where I store the urls to the original images, I would also like to have it save these hundreds of images that it crops, maybe in a directory or in a database, don't know where to start really...........-----------------------------------------------------------------------------------------------------<?php//on top left corner (483, 216)//on top right corner (657, 216)//on bottom left corner (483, 346)//on bottom right corner (657, 346)// 172 width, by 131 high dimensions$imgfile = "http://localhost/pics/pic1.JPG";$cropStartX = 483;$cropStartY = 216;$cropW = 172;$cropH = 131;// Create two images$origimg = imagecreatefromjpeg($imgfile);$cropimg = imagecreatetruecolor($cropW,$cropH);// Get the original sizelist($width, $height) = getimagesize($imgfile);// Cropimagecopyresized($cropimg, $origimg, 0, 0, $cropStartX, $cropStartY, $width, $height, $width, $height);// TODO: write code to save new image// or, just display it like this:header("Content-type: image/jpeg");imagejpeg($cropimg);// destroy the imagesimagedestroy($cropimg);imagedestroy($origimg);?> ----------------------------------------------------------------------------------------------------it works and it crops the image, but I would like to have it do multiple images at the same time, and also have it save the new cropped image for meany suggestions? maybe let it access a database where I supply the url of the images? and have it save the images there, or just create a new directory for the images?, I need to crop hundreds at a timethanks people Quote Link to comment https://forums.phpfreaks.com/topic/3681-saving-cropped-images-to-database-or-directory/ Share on other sites More sharing options...
litebearer Posted February 27, 2006 Share Posted February 27, 2006 With a little adjusting this should do what you want. Simply replace the resize part with your crop code.[code]<?PHP############################################# script to take all the images in a folder and resample them. it will loop through all the images # in a folder and check to see if width is > 800 and/or height > 600 . If the image meets# either of those criteria, the script will resample the image to fall within the guidelines #############################################// set path to image folder$image_folder = "pics";if ($handle = opendir($image_folder)){ while (false !== ($file = readdir($handle))) { if ($file != "." && $file != ".." ) { $image_name = $image_folder . '/' . $file; $image_type = strstr($image_name, '.'); switch($image_type) { case '.jpg': $src = imagecreatefromjpeg($image_name); break; case '.png': $src = imagecreatefrompng($image_name); $totlen = strlen($image_name) - 3; $newname = substr($image_name, 0, $totlen) . "jpg"; unlink($image_name); $image_name = $newname; break; case '.gif': $src = imagecreatefromgif($image_name); $totlen = strlen($image_name) - 3; $newname = substr($image_name, 0, $totlen) . "jpg"; unlink($image_name); $image_name = $newname; break; default: echo "Error Invalid Image Type: " . $image_name . " x x x " . $image_type; die; break; } $width = imagesx($src); $height = imagesy($src); // check that width is 800 or less if ($width > 800) { $ratio_w = 800/$width; } else { $ratio_w = 1; } // check if height is 600 or less if ($height > 600) { $ratio_h = 600/$height; } else { $ratio_h = 1; } // determine which ratio creates the smaller image if ($ratio_w <= $ratio_h) { $aspect_ratio = $ratio_w; } else { $aspect_ratio = $ratio_h; } // new resizing code $new_w = abs($width * $aspect_ratio); $new_h = abs($height * $aspect_ratio); $size = $new_h; $aspect_ratio = $height/$width; //start resizing if ($height <= $size) { $new_w = $width; $new_h = $height; } else { $new_h = $size; $new_w = abs($new_h / $aspect_ratio); } $img = imagecreatetruecolor ($new_w,$new_h); //save image imagecopyresampled ($img,$src,0,0,0,0,$new_w,$new_h,$width,$height); imagejpeg($img, $image_name, 90); imagedestroy($img); } } closedir($handle); }?>[/code]hope it helps.Lite...
