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

image "celule.jpg": https://i.ibb.co/6Ffj6sc/celule.jpg I made my website on my laptop (localserver) and it was working fine. But when I uploaded to my hosting account and tried to view it in my browser, all I get is a blank white screen. No errors, no messages. Just blank screen. I tried different hosts ... same problem ... but the website runs fine on my localhost. what could be the problem ??? I even contacted me hosting company and they told me that PHP server is running fine. Hello,
I am having some troubles and was hoping someone could guide me through it.
Q: When ever I try call my get_status function all I get is a white page of nothing, no errors to work from etc... Can anyone here see what I am doing wrong?
PATH: index.php
NOTICE //<<-- KILLS PAGE
<?php
spl_autoload_register(function ($class) {
include '/lib/' . $class . '.inc';
});
$servers = new servers;
echo $servers->get_servers();
echo "STATUS: ".$servers->get_status("0.0.0.0",80); //<<-- KILLS PAGE
?>
Page works fine until I want to use the status function, I get no errors or anything just a blank page.

Kind regards and thank you.
Ok, this is rather bizarre. First this code... if($postCount > 0) { $i = 0; while($row = $this->db->fetch_assoc($post_pagination->resource())) { // echo $row['post_message']; $content .= ($i % 2 == 0 ? '<tr class="odd">' : '<tr>'); $content .= '<table>'; $content .= '<tr><td>'.$row['username'].'</td></tr>'; $content .= '<tr>'; $content .= '<td><p>'.$row['post_message'].'</p></td>'; $content .= '</tr>'; $content .= '</table>'; $content .= '</tr>'; $i++; } $content .= '<tr><td>| '.$plinks.' |</td></tr>'; } For whatever reason, if I comment out the line with $row['post_message'] everything works as expected. If I leave that in there like it is now, I get a completely blank white page. I've also tried assigning it to a variable within the loop like... $post_message = $row['post_message']; and that works fine, until I try echo'ing it then the same blank white page result. I've double checked the query, both in PHP and in PHPMyAdmin and it is working correctly. Here's the query code: $post_pagination = new pagination($ppg, "SELECT `posts`.`post_id`, `posts`.`post_message`, `cg_accounts`.`id`, `cg_accounts`.`username` FROM `".$this->dbname."`.`threads`, `".$this->dbname."`.`posts` INNER JOIN `crikeyga_central`.`cg_accounts` ON (`cg_accounts`.`id` = `posts`.`userid`) WHERE `posts`.`thread_id`=`threads`.`thread_id` AND `posts`.`thread_id`='".$thread_id."' ORDER BY `posts`.`post_timestamp` ASC"); I've also double checked the pagination class is working as expected, and it's fine in every other page it's used in. Also $ppg is the correct value(simply holds the current page number). $this->dbname is also correct, and as mentioned above the query works in PHPMyAdmin. And $post_pagination->resource() is holding the correct value and I've checked the database class in particular $this->db->fetch_assoc() and that's working fine. Really not having much luck pinning this one down, no errors are coming up(error reporting(E_ALL)). seems strange to me that $row['username'] comes up fine, but $row['post_message'] results in a white page. The values are also what they should be. Any help is appreciated! Thanks, Ace Hello everyone, When I submit my login form to go to my login page it goes to a white page and does not display an error.

Brian 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] .

This is kind of weird, I've tried to figure out what is wrong for a while now, but I really can't seem to figure it out. 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 $img1; } The background of my PNG was transparent, I don't know what I did, but it's now black! I'm thinking it's the image! Not the code, this same code worked before, and I've tried tons of different ways of fixing it. How should I save the image to work correctly? hi, i am trying to generate image gallery. but the problem is that when i upload the png files its thumbnail is generated with black background. JPEG an GIF thumbnail are generated successfully. i want to make background transparent. is there any solution that how i can get rid of it. i am using imagecreatetruecolor($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! 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 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.
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?! 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"); So I'm new to PHP GD, I cant understand why the PNG image will not go transparent, it's just showing a white background.
Could anyone help me out with this?
