PHP - Marking Black Points
I have a picture (attached), where I find the coordinates of black points, because I do not remember any point, so you want every point at which I find coordinates with mark a red cross as watermark.
At the coordinates using this script: <?php if(isset($_GET["obrazek_x"])) file_put_contents("soubor.txt",$_GET["obrazek_x"].",".$_GET["obrazek_y"]."\n",FILE_APPEND); ?> Coordinates I save to an external file in this format: Code: [Select] 602;744 Could you advise me a solution to mark black points? Similar Tutorialswhile ($div=mysql_fetch_array($query4, MYSQL_ASSOC)) { //$div - shows all the entries $row22=mysql_fetch_array($query2, MYSQL_ASSOC); //row22 - shows all the entries that should be checked $name= array($div['date_id']); $datess=$row22['date_id']; if (in_array($datess, $name, true)) { echo '<input type="checkbox" value="' . $div[date_id] .'" checked>' . $div[date] . '</option>'; }else{ echo '<input type="checkbox" value="' . $div[date_id] .'">' . $div[date] . '</option>'; } 1. when echo $row22 shows only the entries that should be checked - working good 2. checkboxes show checked if only the first checkbox is selected or all 3 - if a combination is selected, it is all blank. Any ideas? Thank you hi, i am trying to filter my gps history points. i would like to ignore points if they are too close to the previous position. i can do this like so. $old_lat = $old_long = "0"; foreach($history['data'] as $record) { //calculate distance in meters $distance = distance($record['latitude'], $record['longitude'], $old_lat, $old_long, "V"); if($distance >= 300) { echo 'add(jQuery(this), number += 1, "' . date("d-m-Y @ h:i:s",$record['timestamp']) . '", "map_post.php?n=' . $name . 'u=' . $history['user'] . '", "' . $history['user'] . '", "' . $record['latitude'] . '", "' . $record['longitude'] . '");'; $old_lat = $record['latitude']; $old_long = $record['longitude']; } the problem with the above is that if i arrive home at 6pm on friday and stay outside my house for 24hours, it will show the latest position as at 6pm on fri. i would like it to show the 6pm friday position but with a date 'from and to' time like (28/10/11 18:00 - 29/10/11 18:00) rarther than just (28/10/11 18:00) which looks inacurate. Possible? Ok i have 3 columms right now i have date player and points and what i want is for this script to add up each players points and send it to page as totals decending i have got the page to show them individually but when i do group it only gets one record so i tried to add in the sum points and it gives me a ) Warning: mysql_fetch_assoc() expects parameter 1 to be resource, boolean given in so i am kind of lost as to where adding the sum(points) would cause this below is the code where the problem is any help would be much appreciated
$r = mysql_query("select * from player_points Sum(points) as total where date_entered > '$d' Group by player order by total DESC"); <?php $totalcreditstd = $row_rsCreditPurchaseMoney['SUM(quantity)']; $totalcreditsdollar = $totalcreditstd * $Mutliplier; echo $totalcreditsdollar; ?> I'm using the above calculation to display a total amount. Problem is that if the calculation total is 7.5 I want it to show up as 7.50 I want to force the second number. How can I do that? Thanks. Okay, I'm trying to make it so that when someone levels up in my game, they can use stat bonus points to increase their abilities. However, there doesn't seem to be a break in there to ensure that someone can't spend points that they don't have. For instance, they get 3 per level, but if they spend 6, the system lets them and shows a -3 in their stat_bonus field. Any help would be appreciated!

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] .

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 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? 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? 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.
