PHP - Converting Grayscale Image To Pure Black And White
I'm trying to convert a grayscale image to pure black and white in php using the GD library. The purpose would be to detect the cervical cells within the image. I'll leave the php code and a matlab one (i wrote this code in matlab and i'm trying to obtain the same result in php). Basically, im having troubles accessing each individual pixel's color and modifying it. MATLAB:
clear all, clc, close all;
I = imread('celule.jpg');
imshow(I)
title('original');
a=rgb2gray(I);
figure;
imshow(a)
title('grayscale');
s=size(a);
for i=1:s(1)
for j=1:s(2)
if a(i,j)>190
a(i,j)=0;
else a(i,j)=255;
end
end
end
figure;
imshow(a)
title('pure black and white');
PHP:
<?php
$im = imagecreatefromjpeg("celule.jpg");
function imagetograyscale($im)
{
if (imageistruecolor($im)) {
imagetruecolortopalette($im, false, 256);
}
for ($c = 0; $c < imagecolorstotal($im); $c++) {
$col = imagecolorsforindex($im, $c);
$gray = round(0.299 * $col['red'] + 0.587 * $col['green'] + 0.114 * $col['blue']);
imagecolorset($im, $c, $gray, $gray, $gray);
}
}
imagetograyscale($im);
//imagefilter($im, IMG_FILTER_CONTRAST, -255); //i'm not looking for this effect
header('Content-type: image/jpeg');
imagejpeg($im);
$C = imagesx($im); //width
$L = imagesy($im); //height
echo "Dimensiuni imagine: latime $C, inaltime $L <br>";
//scanning through the image
for($x = 0; $x < $L; $x++) { //each line
for($y = 0; $y < $C; $y++) { //each collumn
// pixel color at (x, y)
$color = imagecolorat($im, $y, $x);
$color = imagecolorsforindex($im, $color); //getting rgb values
$RED[$x][$y] = $color["red"]; //each rgb component
$GREEN[$x][$y] = $color["green"];
$BLUE[$x][$y] = $color["blue"];
}
}
?>

My script does seem to work with the values I think it works with, but that might be where the error is. I've messed around a lot with it, but I still can't seem to understand what the problem is... I do realize I can just use the filledrectangle function instead of creating a new image for each background color, but the problem itself really annoys me. The black line doesn't appear anywhere but between the two first background colors and only if both background colors are visible... o.O Might be I need to use some other imagecopy function, but this is all so weird! <?php // image size $x=500; $y=100; // creating transparent image $im=imagecreatetruecolor($x,$y); $tc=imagecolorallocatealpha($im,255,255,255,0); imagefill($im,0,0,$tc); // background colors // the escaped lines is for making a background image transparent, to see where the black line appears $bgc[]=array(255,0,0,0); //$bgc[0]=array(255,0,0,127); $bgc[]=array(0,255,0,0); //$bgc[1]=array(0,255,0,127); $bgc[]=array(0,0,255,0); $bgc[]=array(0,255,255,0); // adding backgrounds // background count: $bgcq=count($bgc); // backgroundsize x,y: $bgs=array(ceil($x),($y+1)/$bgcq); // location: $bgsl=0; // last height: $bgsh=0; for($i=0;$i<$bgcq;$i++){ // start location for this background: $bgsl+=$bgsh; // calculating a round number for the background height if($bgsl+$bgs[1]<round($bgs[1]+($bgs[1]*$i))){ $bgsh=ceil($bgs[1]); }else{ $bgsh=floor($bgs[1]); } // creating background image: $bg=imagecreatetruecolor($bgs[0],$bgsh); // filling background image with set color $abgc=imagecolorallocatealpha($bg,$bgc[$i][0],$bgc[$i][1],$bgc[$i][2],$bgc[$i][3]); imagefill($bg,0,0,$abgc); // pasting background on image (imagecopy gives the same result) imagecopyresampled($im,$bg,0,$bgsl,0,0,$bgs[0],$bgsh,$bgs[0],$bgsh); // to see the values (test purpose), must escape header and imagepng functions //echo $bgsl.'-'.($bgsl+$bgsh).'<br />'.$bgsh.'<br />'; } // output, remember to escape it to echo variables header('Content-type: image/png'); imagepng($im,NULL,0); ?> I've tried to make the script as understandable and easy as possible... anyone got any ideas about what is wrong here, and how to maybe fix it? function buildAvatar(array $imgArray = array()) { $img1 = imagecreatefrompng($phpbb_root_path.'images/spacer.png'); foreach($imgArray as $img) { $img2 = imagecreatefrompng($phpbb_root_path.'avatars/equip_img/'.$img); $this->imagecopymerge_alpha($img1, $img2, 0, 0, 0, 0, 210, 300, 100); } imagealphablending($img1, false); imagesavealpha($img1, true); return $img1; } The background of my PNG was transparent, I don't know what I did, but it's now black! I'm thinking it's the image! Not the code, this same code worked before, and I've tried tons of different ways of fixing it. How should I save the image to work correctly? this is the code <?php $image = imagecreatefromjpeg("9t4i_200xX.jpg"); $new_image = imagecreatetruecolor(120,90); imagecopyresampled($new_image, $image, 0, 0, 0, 0, 120, 90, imagesx($image), imagesy($image)); $image = $new_image; imagejpeg($image,"images/test.jpg"); ?> result is black jpeg image of size 120,90 I dont understand where could be the problem SimpleImage.php script doesnt work either I am trying to copy an image into another image. Code: [Select] $im = imagecreatefrompng("/oldimg.png"); //this is a semi-transparent image where I want the new image to be copied imagealphablending($im, 1); //this seems to remove the black background header('Content-type: image/png'); //outputs old image with a transparent background (YAY!) imagepng($im); imagecopy($im, $newimage, 32, 0, 0, 0, 32, 32); //I want to replace a part of the old image with a new semi-transparent image header('Content-type: image/png'); //outputs image with a black background (noooooooooo!) imagepng($im); Can anyone help me? Hi im having trouble with uploading images with spaces in as they dont show up in the browser. Here is the code: Code: [Select] $image = addslashes($_FILES['image']['name']); $target = "images/"; $target = $target . basename( $_FILES['image']['name']); //Writes the photo to the server if(move_uploaded_file($_FILES['image']['tmp_name'], $target)) { Any help would be appreciated. Is there a way to use php to incorporate a folder of pictures as a clickable slideshow. For instance.... using a pic as a button... to go to the next pic.... except in quantities of 100... without having to manually write the code for each page...? In HTML: Code: [Select] <a href="index3.html"><img src="2.jpg" /></a> <a href="index4.html"><img src="3.jpg" /></a> <a href="index5.html"><img src="4.jpg" /></a> <a href="index6.html"><img src="5.jpg" /></a> <a href="index7.html"><img src="6.jpg" /></a> <a href="index8.html"><img src="7.jpg" /></a> <a href="index9.html"><img src="8.jpg" /></a> Something like using a basic rotating script activated on mouse click? How do i convert this into a button without making 100 pages? Code: [Select] <img src="/path/to/images/ rotate.php?img=my_static_image.jpg" /> I have come up with the rotate.php file as following: Code: [Select] <?php $folder = '/oprah/is/sofuckingfat.com/images/'; $extList = array(); $extList['gif'] = 'image/gif'; $extList['jpg'] = 'image/jpeg'; $extList['jpeg'] = 'image/jpeg'; $extList['png'] = 'image/png'; /* I believe that most of the following can be omitted once it hits the timer / countdown script */ $img = null; if (substr($folder,-1) != '/') { $folder = $folder.'/'; } if (isset($_GET['img'])) { $imageInfo = pathinfo($_GET['img']); if ( isset( $extList[ strtolower( $imageInfo['extension'] ) ] ) && file_exists( $folder.$imageInfo['basename'] ) ) { $img = $folder.$imageInfo['basename']; } } else { $fileList = array(); $handle = opendir($folder); while ( false !== ( $file = readdir($handle) ) ) { $file_info = pathinfo($file); if ( isset( $extList[ strtolower( $file_info['extension'] ) ] ) ) { $fileList[] = $file; } } closedir($handle); if (count($fileList) > 0) { $imageNumber = time() % count($fileList); $img = $folder.$fileList[$imageNumber]; } } if ($img!=null) { $imageInfo = pathinfo($img); $contentType = 'Content-type: '.$extList[ $imageInfo['extension'] ]; header ($contentType); readfile($img); } else { if ( function_exists('imagecreate') ) { header ("Content-type: image/png"); $im = @imagecreate (100, 100) or die ("Cannot initialize new GD image stream"); $background_color = imagecolorallocate ($im, 255, 255, 255); $text_color = imagecolorallocate ($im, 0,0,0); imagestring ($im, 2, 5, 5, "IMAGE ERROR", $text_color); imagepng ($im); imagedestroy($im); } } ?> Would be more or less converting the rotate.php script into the base for the link structure. I assume the timing element in this script would be omitted with a replacement or nothing. I can't figure out what will be the quickest way to go about making the href follow the folder contents. I just want a basic click on the pic to go to the next one until it ends. Thoughts anyone? I have found a point in my site where the user may wish to go back a page. Using the back button in the browser works perfectly fine. However, for aesthetical reasons and for "obvious function" reasons i need to create a button on the page which goes back a step in the browsers history. I know I can do this with Javascript, but I would rather get it done with php first. Therefore is it possible to create a back button in PHP. The back button in question will go back one step in the browsers history to the same .php it is currently on but in a previous state. I found this from google, http://www.webmasterworld.com/forum88/870.htm, but then found there was some js in the answers. I cannot find any other posts similar to this in php freaks hi guys i need some help i am trying to create a resized image with a watermark, from an uploaded image.. the image is getting uploaded and resized but the watermark doesnt appear correct. instead of a transparent watermark, there's a black square in it's place. this is my code Code: [Select] $tempfile = $_FILES['filename']['tmp_name']; $src = imagecreatefromjpeg($tempfile); list($origWidth, $origHeight) = getimagesize($tempfile); // creating png image of watermark $watermark = imagecreatefrompng('../imgs/watermark.png'); // getting dimensions of watermark image $watermark_width = imagesx($watermark); $watermark_height = imagesy($watermark); // placing the watermark $dest_x = $origWidth / 2 - $watermark_width / 2; $dest_y = $origHeight / 2 - $watermark_height / 2; imagecopyresampled($src, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $origWidth, $origHeight); imagealphablending($src, true); imagealphablending($watermark, true); imagejpeg($src,$galleryPhotoLocation,100); // $galleryPhotoLocation is correct. the image gets uploaded successfully.. I'm importing a CSV using the fgetcsv() function, which is working all good. However, when I take a look at the data in the database, I see black diamonds with question marks. This isn't too much of an issue when echoing the data back out again, as they don't appear, but when I want to use one of the CSV fields as a MySQL date, it isn't recognised as a date and is stored as 0000-00-00. e.g. I think this issue is something to do with encoding of the CSV? Can anyone offer any advice? If it helps here is my import script, and the encode type is ASCII according to mb_detect_encoding Code: [Select] <?php include 'config.php'; include 'opendb.php'; ini_set("auto_detect_line_endings", true); $row = 0; $tmpName = $_FILES['csv']['tmp_name']; if (($handle = fopen($tmpName, "r")) !== FALSE) { $num = count($data); while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $noQuotes = str_replace("\"", '', $data); $originalDate = $noQuotes[1]; //$delivery_date = date('Y-m-d', strtotime($originalDate)); $parts = explode('/', $originalDate); $delivery_date = $parts[2] .

JPEG an GIF thumbnail are generated successfully. i want to make background transparent. is there any solution that how i can get rid of it. i am using imagecreatetruecolor($thumbwidth, $thumbheight ); to generate thumbnail Hey all. I'm getting down the basics of the GD Library's image creation processes. I'm trying to test out creating png images. However, where there should be transparency there is a black background. Here's my code mostly based on the image tutorial found here at phpfreaks. Code: [Select] <?php // font $font = 'c:\windows\fonts\arial.ttf'; $fontsize = 12; // array of quotes $quotes = array( "I like pie.", "Surf's Up.", "Smoke em if you got em.", "Game on.", "I need TP for my bunghole."); // select quote $pos = rand(0,count($quotes)-1); $quote = $quotes[$pos]; // image $image = imagecreatefrompng('quote.png'); $white = imagecolorallocate($image, 255, 255, 255); $black = imagecolorallocate($image, 0, 0, 0); imagettftext($image, 11, 0, 107, 32, $black, $font, $quote); imagettftext($image, 11, 0, 105, 30, $white, $font, $quote); // tell the browser that the content is an image header('Content-type: image/png'); // output image to the browser imagepng($image); // delete the image resource imagedestroy($image); ?> Cheers all, thanks! Hi All, Everything is working pretty good, its just the thumbnail portion that adds a black background to every picture it converts. When the user uploads a picture, I take the original picture and then make a thumbnail, so I have 2 images in my fileroot. The original picture looks just fine, its just when I open the thumbnail. Attached is a sample of the black background picture. Below is just the thumbnail portion of the code. Code: [Select] include('uploads/image.php'); $image = $path; $thumb = new SimpleImage(); $thumb->load($image); $width = 150; $height = 95; $thumb->resize($width,$height); $thumb->save('uploads/thumbnails/'.$filename); image.php Code: [Select] class SimpleImage { var $image; var $image_type; function load($filename) { $image_info = getimagesize($filename); $this->image_type = $image_info[2]; if( $this->image_type == IMAGETYPE_JPEG ) { $this->image = imagecreatefromjpeg($filename); } elseif( $this->image_type == IMAGETYPE_GIF ) { $this->image = imagecreatefromgif($filename); } elseif( $this->image_type == IMAGETYPE_PNG ) { $this->image = imagecreatefrompng($filename); } } function save($filename, $image_type=IMAGETYPE_JPEG, $compression=75, $permissions=null) { if( $image_type == IMAGETYPE_JPEG ) { imagejpeg($this->image,$filename,$compression); } elseif( $image_type == IMAGETYPE_GIF ) { imagegif($this->image,$filename); } elseif( $image_type == IMAGETYPE_PNG ) { imagepng($this->image,$filename); } if( $permissions != null) { chmod($filename,$permissions); } } function output($image_type=IMAGETYPE_JPEG) { if( $image_type == IMAGETYPE_JPEG ) { imagejpeg($this->image); } elseif( $image_type == IMAGETYPE_GIF ) { imagegif($this->image); } elseif( $image_type == IMAGETYPE_PNG ) { imagepng($this->image); } } function getWidth() { return imagesx($this->image); } function getHeight() { return imagesy($this->image); } function resizeToHeight($height) { $ratio = $height / $this->getHeight(); $width = $this->getWidth() * $ratio; $this->resize($width,$height); } function resizeToWidth($width) { $ratio = $width / $this->getWidth(); $height = $this->getheight() * $ratio; $this->resize($width,$height); } function scale($scale) { $width = $this->getWidth() * $scale/100; $height = $this->getheight() * $scale/100; $this->resize($width,$height); } function resize($width,$height) { $new_image = imagecreatetruecolor($width, $height); imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width, $height, $this->getWidth(), $this->getHeight()); $this->image = $new_image; } } hello, here is what i have. i feel like im close. Code: [Select] $result4 = mysql_query("SELECT * FROM schedule WHERE eid = '$posteid' AND status = 1 OR 2"); Hello.
The first page works, but when form actioning to the next i just get a white screen.
This is the white screen page:
<?php session_start(); include 'details.php'; $username = $_POST['username']; $password = $_POST['password']; $pwswdrd = md5($password); if(!empty($_POST['username'])) { $query = mysqli_query($con, "SELECT * FROM users where name = '$username' AND pass = '$pwswdrd'") or die(mysqli_connect_error()); $row = mysqli_fetch_array($query); if(!empty($row['name']) AND !empty($row['pass'])) { $_SESSION['username'] = $row['username']; $_SESSION['id'] = $row['id']; header('Location: index.php'); } } else { echo "You failed to log in."; } ?> - details.php <?php $one=mysqli_connect('.......webhost.com','aee','aaa') or die("Failed to connect to MySQL: " . mysqli_error() ); $db=mysqli_select_db($one,'aee') or die("Failed to connect to MySQL: " . mysqli_error() ); ?> -- What can possibly be wrong?! Would someone please take a look at this. I am trying to use a form to allow users to answer yes or no with radio buttons, and then print it out on another page. I can only get the script to print the number 1 no matter which button is selected. When I check the database the number 1 is recorded no matter which button is selected. In the top of the input form I have Code: [Select] <input type='hidden' name='electricity' value='0'>In the body of the input form I have Code: [Select] Electricity <input type='radio' name='electricity' value='0'>no <input type='radio' name='electricity' value='1'>yesAnd on the output page I have Code: [Select] $electricity = $row['electricity']; if ($electricity == 1) { $answer = "YES"; } else { $answer = "NO"; }and Code: [Select] echo $row['electricity'];I have been over and over this and can not discover my error. Thank you for looking. Hi All, I am trying to "echo" a result from a SQL query, that returns a size in KB, but I want this to read in MB or GB - can PHP change this for me, or is it something I need to do in SQL? Cheers Matt xml file: Code: [Select] <PRICES> <PRICE> <WIC>HDE0AAFGRBOX</WIC> <STOCK>100+</STOCK> <MY_PRICE>219.00</MY_PRICE> </PRICE> </PRICES>php file: Code: [Select] <? $filexml='stock.xml'; if (file_exists($filexml)) { $xml = simplexml_load_file($filexml); $f = fopen('stock.csv', 'w'); foreach($xml->PRICES->PRICE as $price) { fputcsv($f, get_object_vars($price),',','"'); } fclose($f); } ?> Error: Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\stock.php on line 6 Please help with this. |
