PHP - Gd Library - Colorize Non-transparent Areas In Image
I'm wondering if the GD library is capable of coloring ONLY the non-transparent areas in an image. I had this image white, black, and every other color under the moon, but could only get GD to color the entire canvas (width and height) of the image with an opacity over it. I'm merging many layers on top of each other so I can't afford to color the entire square and lower the opacity and do some weird multiply stuff.
That's the image above. Then I have some lineart, markings, eye color, etc. So I had all my possible colors white areas that I layer on top of eachother. I want to color the entire non-transparent areas with a color (dynamic).. so I can't just color it in Photoshop and then upload it or else I would literally have millions of possibilities for every single color and shade..
Thanks for any help. I was trying to go with ImageMagick if GD isn't capable, but I can't even get that downloaded in my Wamp. I'm using 64 bit Wamp so I have no idea if that does something or whatever. I can get it installed on my computer and run it via command line, but I can't get it to work and render images in my Wamp files... can't ever find a .dll that works.
Similar TutorialsHello folks. I have a system showing stock of products. Now I want to colorize the value based on how much it is. For example 0 is red and then green is 10 000 and up. So the range should be like a smooth gradient. What's the algorithm?
How to implement the library
here's my code
<?php
include("../incs/config.php");
$result = mysqli_query($link, "SELECT * FROM press ORDER BY press_date DESC");
$result2 = mysqli_query($link, "SELECT * FROM event ORDER BY event_date DESC");
$result3 = mysqli_query($link, "SELECT * FROM galleries ORDER BY gallery_id DESC");
if (!isset($_COOKIE['user'])) {
die("Identifiant invalide");
}

Edited October 16, 2019 by samplephp I am trying to create a basic image with GD library, but my browser says that the image cannot be displayed because it contains errors... I have no idea why. Here's my code: Code: [Select] switch($_GET['case']){ case "progressbar": header('Content-Type: image/jpeg'); $barWidth = 6; $barHeight = 14; $barPadding = 2; $imageWidth = ($barWidth * 10) + (10 * $barPadding); $imageHeight = ($barHeight + ($barPadding * 2)); $img = @imagecreate($imageWidth, $imageHeight); $imgBorder = imagecolorallocate($img, 0, 0, 0); //imagefilledrectangle($img, 1, $imageHeight -1, $imageWidth - 1, $imageHeight - 1, $imgBorder); $output = "Hello, world!"; imagestring($img, 1, 4, 4, $output, $imgBorder); imagejpeg($img); imagedestroy($img); break; } I have a file called image.php that i use to create images and I use the URL image.php?case=progressbar. 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 work out how I can use php gd to take an image, in this case it’s a rectangle that has text in the middle and the rest is transparent, so it’s a png with just text in the centre.
I have another image which is a texture. Its also a rectangle of the same size. I have managed to merge the two together so the texture on top of the text image but it covers the entire image rather than just the text in the middle.
what I need it to do it apply the texture to the text in the image and ignore the surrounding transparent pixels.
This is the script i am using i two areas , but the goal is not the same :( Code: <div class='allDeal'> <div class='date'><?php echo app()->locale->dateFormatter->formatDateTime( utime($data->start,false),'medium',false); ?></div> <div class='content'> <div class='name'><?php echo CHtml::link($data->name,url('/deal/view',array('url'=>$data->url))); ?></div> <div class='clearfix prepend-top'> <div class='column data'> <div class='stats txt-center'> <span class='num'><?php echo $data->stats && $data->stats->bought?$data->stats->bought:'0'; ?></span><br /> <?php echo $this->t('Coupons Bought'); ?> </div> <div class='info prepend-top'> <div class='row price'> <label><?php echo $this->t('Price').':'; ?></label> <?php echo m('payment')->format($data->price); ?> </div> <div class='row'> <label><?php echo $this->t('Value').':'; ?></label> <?php echo m('payment')->format($data->value); ?> </div> <div class='row'> <label><?php echo $this->t('Savings').':'; ?></label> <?php echo m('payment')->format($data->value-$data->price); ?> </div> </div> </div> <div class='column last image'><?php if($data->imageBin) echo CHtml::link( CHtml::image(app()->storage->bin($data->imageBin)->getFileUrl('original')), url('/deal/view',array('url'=>$data->url)) ); ?></div> </div> </div> </div><?php if($index && ($index+1)%2==0) { ?><div class='clearfix'></div><?php } Only change: div class='allDeal' to div class='recentDeal' This is the good: http://kupon.woano.lv/deal/recent and the same code in other place looks ugly :( http://kupon.woano.lv/deal/all What i am doing wrong Assist a newbie! Hi there, I got some good advice from Harristweed the other day about how to export from Mysql to excel, so that each field appears in a different column in excel. I expanded the code Harristweed gave me to cover all fields in my database, and all went well until the 2nd last field, when I hit a brick wall. Unlike previous fields, which were based on info inputted via radio buttons, dropdown lists, or text boxes, the field causing problems was based on data that came from a text area on the web form. A few tests revealed that the problem was related to when a user pressed the "Enter" key while filling in that field, to begin a new paragraph. When this happens, it would go into the database fine. However, when I used the code to export it to excel, anything after the "Enter" key had been pressed would appear in a new cell on a new row, thereby putting the table out of alignment. I could get around this by rewording the question into a few questions which each use a text box rather than a text area box. However, if there is a way to get around this by tweaking the php code, I'd love to know. The field with which I'm having the problem is the one called "experience".

So I did and now I get the message: Unable to Load Dynamic Library in a pop-up window. I'm lost and don't know how to solve this What do I need to do in order to use the libssh2 library? Hi, I would like my users to create and save forms via mysql. They should be able to choose what field they want to use, and other users should be able to fill the forms into mysql. Any ideas on how to accomplish this? I'm trying to write a script that will copy images from one website (a supplier, in this case puma) and save them to the dealer's web server. I have already done this for other supplier's websites but puma uses png's instead of jpeg's and I believe that is what is causing my issues: The original image looks like this: The copied image some odd colors in the background like this: Here is the code: Code: [Select] $puma_image = "http://www.pumab2b.com/_static/images/styleColors/1234560002/" . str_replace(" ", "", $Item_Num) . "_1.png"; $image = imagecreatefrompng($puma_image); if ($image) { //Save image to Soccer Etc server (images folder): if (imagepng($image, "prod_images/" . $cur_Item['Item_Num'] . ".png", 0)) { //DO some other stuff here } } I just noticed after posting the original image on this forum, that it is actually transparent. I'm guessing this has something to do with my problems? I want to create a media library in the CMS, similar to how it is in WordPress but custom-coded in PHP on my own site. Can this be done simply with a database connection or will the images need to be uploaded to a server? Bit confused as to how it works and which is the best way to go about it. Thanks for any help.

Here is what I have so far for the form page: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>Untitled Document</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <label>Seat Color Choices:</label><br> Red<input type="radio" name="color" value="red" id="red" onFocus="getElementById('config').src = 'red.php'" > Orange<input type="radio" name="color" value="orange" id="orange" onFocus="getElementById('config').src = 'orange.php'" > Ivory<input type="radio" name="color" value="ivory" id="ivory" onFocus="getElementById('config').src = 'ivory.php'" > Black<input type="radio" name="color" value="black" id="black" onFocus="getElementById('config').src = 'black.php'" > </form> <img src="black.php" id="config" alt="color choice for lola chair"> </body> </html> ...and here is one of my image files for an example: <?php //Report any errors ini_set ("display_errors", "1"); error_reporting(E_ALL); //Set the correct content type header('content-type: image/jpeg'); $base = imagecreatefromjpeg('lola_base.jpg'); $red = imagecreatefromgif('lola_red.gif'); $orange = imagecreatefromgif('lola_orange.gif'); $ivory = imagecreatefromgif('lola_ivory.gif'); $black = imagecreatefromgif('lola_black.gif'); imagecopy($base, $red, 0 , 0 , 0, 0,250, 250); imagejpeg($base); //Clear up memory used imagedestroy($base); ?> The problem is, I need to be able to dynamically change which images are being combined. I can't have a different file for each combo (ex. red.gif, black.gif, ivory.gif, etc.) I need it to create them on cue from a single file/function. Is there a way to do that with PHP GD library? GD Library Pattern Background ? Hi all I have a simple page here that uses the GD Library to display text in a selected font and size etc. http://www.ttmt.org.uk/forum/ At moment the stripped background goes from the code. Is there a way to have an image as the background instead of the stripped background. PHP code Code: [Select] <?php header('Content-Type: image/png'); $im = imagecreatetruecolor(900, 215); $w = imagecolorallocate($im, 255, 255, 255); $c = imagecolorallocate($im, 220, 220, 220); $black = imagecolorallocatealpha($im, 0, 0, 0, 20); $style = array($w,$w,$w,$c,$c,$c); ImageSetStyle($im, $style); ImageLine($image, 100, 0, 50, 50, IMG_COLOR_STYLED); imagefilledrectangle($im, 0, 0, 900, 214, IMG_COLOR_STYLED); $text = $_GET['text']; $textSize = $_GET['size']; $font = $_GET['font']; imagefttext($im, $textSize, 0, 15, 165, $black, $font, $text); imagepng($im); imagedestroy($im); ?> Hello everyone, What is the best way to take HTML formatted text and overlay it on a image (presumably using php's GD functions)? Unfortunately, HTML tags are ignored and any kind of code is treated as plaintext by imagefttext(). However, I need this HTML DIV box pasted onto an image and I intend to get it done. To make things slightly worst, this is a dynamic, PHP generated DIV box. I had an idea of utilizing some kind of buffering to generate my DIV box, convert that DIV box to an image and finally paste it onto my image using the GD library. If that sounds like a reasonable idea, can someone please help me get started? Thanks in advance, guys! 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? Code: [Select] <?php header('Content-Type: image/png'); $im = imagecreatetruecolor(1000, 200); $gray = imagecolorallocate($im, 240, 240, 240); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, 1000, 199, $gray); $text = $_GET['text']; $textSize = $_GET['size']; $font = $_GET['font']; imagefttext($im, $textSize, 0, 15, 160, $black, $font, $text); imagepng($im); imagedestroy($im); ?> Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>untitled</title> <style type="text/css"> *{margin:0;padding:0;} #wrap{margin:20px 0 0 20px;} h1{margin:0px 0 20px 0;clear:both;} h2{font-size:1.1em;margin:15px 0 5px 0;} #top{padding:0 0 20px 0;} form{margin:0 0 20px 0;} </style> </head> <body> <div id="wrap"> <form action="index.php" method="post"> <!--<input type="text" name="text" value="<?php echo $_POST['text'];?>" />--> <select name="text" > <option value="<?php echo $_POST['text'];?>">Text</option> <option value="ABCDEFGHIJKLMNOPQRSTUVWXYZ">ABCDEFGHIJKLMNOPQRSTUVWXYZ</option> <option value="abcdefghijklmnopqrstuvwxyz">abcdefghijklmnopqrstuvwxyz</option> <option value="0123456789">0123456789</option> </select> <select name="size"> <option value="<?php echo $_POST['size'];?>">Size</option> <option value="10">10</option> <option value="12">12</option> <option value="14">14</option> <option value="18">18</option> <option value="24">24</option> <option value="30">30</option> <option value="38">38</option> <option value="42">42</option> <option value="50">50</option> <option value="60">60</option> <option value="80">80</option> <option value="100">100</option> </select> <input type="submit" name="submit" value="Set →" /> </form> <div id="top"> <?php $theFont="corbelb.ttf"; if(!empty($_POST['submit'])){ $myText = $_POST['text']; $mySize = $_POST['size']; echo '<img src="imageftt.php?text='.$myText.'&size='.$mySize.'&font='.$theFont.'">'; }else{ $myText = "Handgloves"; $mySize = 24; echo '<img src="imageftt.php?text='.$myText.'&size='.$mySize.'&font='.$theFont.'">'; } ?> </div> </div> </body> </html> hi, i'm using the fpdf library to generate PDF's from form input. It all worked well on my local host, but now that i have transferred to a web server it displays the following error when trying to generate a PDF. Warning: require(/fpdf16/fpdf.php) [function.require]: failed to open stream: No such file or directory in /home/ddgq0o2n/public_html/quote_builder/pdf.php on line 2 Fatal error: require() [function.require]: Failed opening required '/fpdf16/fpdf.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/ddgq0o2n/public_html/quote_builder/pdf.php on line 2 i have searched for "include_path", but can't find it anywhere. i'm thinking it's a server problem, where the library may not be compatible or something needs to be switched on, as it worked fine on my local host. any help and suggestions welcome thanks. |
