PHP - How Do I Adjust The Size With Gd ??
Hello:
Hoping someone can help me figure this out... I am resizing a photo/thumbnails with GD (I think that's the correct term) upon uploading. Works fine but the one thing I can't figure out is how to scale the height proportionate with the width. Meaning, I have the width set to 690px, and the height set to 500px. It is making the images look squished. What I would like to do is have a set width (like 690px), but have the height scale down proportionalety. Or, can I just remove the height (although I tried that and it did not work). This is the code: Code: [Select] // Let's get the Thumbnail size $size = GetImageSize( $images_dir."/".$filename ); if($size[0] > $size[1]) //{ //$thumbnail_width = 100; //$thumbnail_height = (int)(100 * $size[1] / $size[0]); //} //else //{ //$thumbnail_width = (int)(100 * $size[0] / $size[1]); //$thumbnail_height = 100; //} { //$thumbnail_width = 690; //$thumbnail_height = (int)(500 * $size[1] / $size[0]); $old_width = $size[0]; $old_height = $size[1]; $thumbnail_width = 690; $thumbnail_height = ($old_height * $thumbnail_width / $old_width); } else { $thumbnail_width = (int)(690 * $size[0] / $size[1]); $thumbnail_height = 500; } // Build Thumbnail with GD 1.x.x, you can use the other described methods too $function_suffix = $gd_function_suffix[$filetype]; $function_to_read = "ImageCreateFrom".$function_suffix; $function_to_write = "Image".$function_suffix; // Read the source file $source_handle = $function_to_read ( $images_dir."/".$filename ); if($source_handle) { // Let's create an blank image for the thumbnail //$destination_handle = ImageCreate ( $thumbnail_width, $thumbnail_height ); $destination_handle = imagecreatetruecolor( $thumbnail_width, $thumbnail_height ); // Now we resize it ImageCopyResized( $destination_handle, $source_handle, 0, 0, 0, 0, $thumbnail_width, $thumbnail_height, $size[0], $size[1] ); } // Let's save the thumbnail $function_to_write( $destination_handle, $images_dir."/tb_".$filename ); ImageDestroy($destination_handle ); // $result_final .= "<img src='".$images_dir. "/tb_".$filename."' style='margin-right: 20px; width: 100px;' />"; Anyone have any ideas on this? Thanks much. Similar TutorialsI need to adjust mod rewrites from an admin panel. Any ideas on how to do this? could someone help in how to resize a uploaded image size, say if someone is uploading a 1mb photo to my server, i wish for it to become 100kb and also resize its width and height? here is my code Code: [Select] //////////////////////////////////////uploader else if($action=="uploader") { echo "Upload your picture and copy the link <br/>after uploading to user it at gallery.<br/><br/>"; echo "<form method=\"post\" enctype=\"multipart/form-data\" action=\"index.php?action=uploaded&sid=$sid\">"; echo "Choose Pictu <br />"; echo "<input name=\"uploaded\" type=\"file\" /><br /><br />"; echo "<input type=\"submit\" value=\"Upload\" />"; echo "</form><br/>"; echo "<p align=\"center\">"; echo "<a href=\"index.php?action=main&sid=$sid\">Home</a>"; echo "</p>"; } //////////////////////////////////////uploader else if($action=="uploaded") { $blacklist = array(".php", ".php.jpg", ".php.jpeg", ".php.gif", ".php.png", ".phtml", ".php3", ".php4"); foreach ($blacklist as $item) { if(preg_match("/$item\$/i", $_FILES['uploaded']['name'])) { echo "<p align=\"center\">"; echo "Oops sorry we do not allow those files.<br/>"; echo "<a href=\"index.php?action=main&sid=$sid\">Home</a>"; echo "</p>"; exit; } } $target = "../images/"; $target = $target . basename( $_FILES['uploaded']['name']) ; $ok=1; if (file_exists("../images/" . $_FILES["uploaded"]["name"])) { echo "<p align=\"center\">"; echo $_FILES["file"]["name"] .

Hi there, In a string for a shopping cart I am storing both the item id and the item size selected in a number like this 12s1 where 12 is the id and 1 is the size.

Font size GD Library Hi All I'm trying to create a font tester - http://www.ttmt.org.uk/fonts/index.php (this demo doesn't use the font I'm using.). I'm using the GD library to create images of the text. I'm not happy with the quality of the fonts at small sizes. I've tried everything to fix it but nothing is working. One suggestion I had was to create the fonts larger then reduce the size of the image. Can anyone offer any advise how I might do this?

I'm trying to get the size of the BLOB data in mysql. Did a search and there are like no tutorial on this. Only relevant info was from this page, at the far bottom, it just wrote this (below code). But the writer did not explain how to use it. SELECT OCTET_LENGTH(content) FROM BloBTest WHERE filename='myimage.png' I just give it a trial an error, wrote this, but did not work. $LENGTH = mysql_query("SELECT OCTET_LENGTH(blobdata) FROM thedatabase WHERE id = 'selected_id'"); echo $LENGTH; Please help.... Hi, I'm using the script below to that allows a user to upload a photo, which then appears on the page as a thumbnail, the image can be clicked and opens up in a lightbox image pop up. All this works fine except the images are not resizing. I.e if a a picture is 1024px wide, before upload - it stays that size on the server. I need it to compress down to around 600px wide and have the KB of the file reduced. I know that I should be using GD library to do this but not sure how to implement it. The script I am using is he ############################################################################################## function upload($user_id,$fileid) ############################################################################################## { global $db; $maxsize = $_POST['MAX_FILE_SIZE']; if(is_uploaded_file($_FILES['userfile']['tmp_name'][$fileid])) { if($_FILES['userfile']['size'][$fileid] < $maxsize) { $imgData = addslashes(file_get_contents($_FILES['userfile']['tmp_name'][$fileid])); $size = getimagesize($_FILES['userfile']['tmp_name'][$fileid]); $sql_query = "SELECT * FROM user_images WHERE image_id = '999999999999999999'"; if(mysqli_num_rows(mysqli_query($db, $sql_query)) > 0) { $sql_query = "UPDATE user_images SET image_type = '{$size['mime']}', image = '{$imgData}', image_size = '{$size[3]}', image_name = '{$_FILES['userfile']['name'][$fileid]}' WHERE image_id = '$user_id'"; } else { $sql_query = "INSERT INTO user_images ( image_type ,image, image_size, image_name) VALUES ('{$size['mime']}', '{$imgData}', '{$size[3]}', '{$_FILES['userfile']['name'][$fileid]}')"; } if(!mysqli_query($db,$sql_query)) { echo '<div class="error">Unable to upload file</div>'; } else { $return = mysqli_insert_id($db); } } else { echo '<div>File exceeds the Maximum File limit.
