I made an image combining 3 different images, but I need a transparent background, and I don't succeed doing it. This is my final code:
<?php
$meko = $_GET['image'];
$im = $meko;
$bookback = "images/book_back.png";
$mekoCanvas = imagecreatetruecolor(115, 135);
$canvas = imagecreatetruecolor(115, 185);
$bookback = imagecreatefrompng($bookback);
$meko = imagecreatefromjpeg($meko);
imagecopy($mekoCanvas, $meko, 0, 0, 0, 0, 100, 135);
imagecopy($mekoCanvas, $bookback, 100, 0, 0, 0, 15, 135);
$im = $mekoCanvas;
$rH = 50; // Reflection height
$tr = 30; // Starting transparency
$div = 1; // Size of the divider line
$w = 115;
$h = 135;
//$im = imagecreatefromjpeg($im);
$li = imagecreatetruecolor($w, 1);
$bgc = imagecolorallocate($li, 255, 255, 255); // Background color
imagefilledrectangle($li, 0, 0, $w, 1, $bgc);
$bg = imagecreatetruecolor($w, $rH);
$wh = imagecolorallocate($im,255,255,255);
$im = imagerotate($im, -180, $wh);
imagecopyresampled($bg, $im, 0, 0, 0, 0, $w, $h, $w, $h);
$im = $bg;
$bg = imagecreatetruecolor($w, $rH);
for ($x = 0; $x < $w; $x++) {
imagecopy($bg, $im, $x, 0, $w-$x, 0, 1, $rH);
}
$im = $bg;
$in = 100/$rH;
for($i=0; $i<=$rH; $i++){
if($tr>100) $tr = 100;
imagecopymerge($im, $li, 0, $i, 0, 0, $w, 1, $tr);
$tr+=$in;
}
imagecopymerge($im, $li, 0, 0, 0, 0, $w, $div, 100); // Divider

You're not telling GD to use alpha in any of your code. That's done with imagesavealpha, imagealphablending, etc...
Try using
imagecolortransparent($im);

and this is how the image look like in the webpage : webpagescreenshot
and the problem is, i wanna add bevel and emboss to the image and also a border radius around 20px or something , and of course we could do that with css
but when the user download the image , the style of course will be gone. i've been trying lookin for canvas option to make bevel and emboss looks realistic like photoshop bevel and emboss , and this is the image i want to achieve : this one made by photoshop
so when they download the image they will get image with border radius and bevel as well ,so is there is a way to do this image effect with phpgd or canvas?, thanks for your help. and sorry for my bad english.
I am trying to copy image (to $img) after rotating image (many images $im) but I get weird behavior. Once I un-comment the line //$img = I only get the rotated image on my final output. Can I rotate the inner $im and copy it to final image$img?
<?php
$height = 80;
$width = 300;
$img = imagecreate($width, $height);
$c = imagecolorallocate ($img , 135, 135, 135);
imagefill($img, 0, 0, imagecolorallocate($img, 255, 255, 255));
for($i=0; $i<=5; $i++){
$im = imagecreatetruecolor(35, 35);
$gry = imagecolorallocate($im, 135, 135, 135);
$wht = imagecolorallocate($im, 255, 255, 255);
$j = mt_rand(0, 1);
$ch = mt_rand(0,1)?chr(rand(65, 90)):chr(rand(97, 122));
if($j == 0){
imagefill($im, 0, 0, $wht);
imagefttext($im, 20, 0, 3, 21, $gry, 'AHGBold.ttf', $ch);
//$img = imagerotate($im, mt_rand(0,10)-5, $wht);
}else{
imagefill($im, 0, 0, $gry);
imagefttext($im, 20, 0, 3, 21, $wht, 'AHGBold.ttf', $ch);
//$img = imagerotate($im, mt_rand(0,10)-5, $gry);
}
imagecopyresampled($img, $im, 5 + $i*42, $height/2 - 12, 0, 0, 40, 40, 25, 25);
}
header('Content-type: image/png');
imagepng($img);
change
$img = imagerotate($im, mt_rand(0,10)-5, $wht);
and
$img = imagerotate($im, mt_rand(0,10)-5, $gry);
to
$im = imagerotate($im, mt_rand(0,10)-5, $wht);
and
$im = imagerotate($im, mt_rand(0,10)-5, $gry);
in cases that imagerotes does not work you can use the following function to rotate an image:
function imagerotateEquivalent(&$srcImg, $angle, $bgcolor, $ignore_transparent = 0)
{
$srcw = imagesx($srcImg);
$srch = imagesy($srcImg);
if($angle == 0) return $srcImg;
// Convert the angle to radians
$theta = deg2rad ($angle);
// Calculate the width of the destination image.
$temp = array ( rotateX(0, 0, 0-$theta),
rotateX($srcw, 0, 0-$theta),
rotateX(0, $srch, 0-$theta),
rotateX($srcw, $srch, 0-$theta)
);
$minX = floor(min($temp));
$maxX = ceil(max($temp));
$width = $maxX - $minX;
// Calculate the height of the destination image.
$temp = array ( rotateY(0, 0, 0-$theta),
rotateY($srcw, 0, 0-$theta),
rotateY(0, $srch, 0-$theta),
rotateY($srcw, $srch, 0-$theta)
);
$minY = floor(min($temp));
$maxY = ceil(max($temp));
$height = $maxY - $minY;
$destimg = imagecreatetruecolor($width, $height);
imagefill($destimg, 0, 0, imagecolorallocate($destimg, 0,255, 0));
// sets all pixels in the new image
for($x=$minX;$x<$maxX;$x++) {
for($y=$minY;$y<$maxY;$y++)
{
// fetch corresponding pixel from the source image
$srcX = round(rotateX($x, $y, $theta));
$srcY = round(rotateY($x, $y, $theta));
if($srcX >= 0 && $srcX < $srcw && $srcY >= 0 && $srcY < $srch)
{
$color = imagecolorat($srcImg, $srcX, $srcY );
}
else
{
$color = $bgcolor;
}
imagesetpixel($destimg, $x-$minX, $y-$minY, $color);
}
}
return $destimg;
}
function rotateX($x, $y, $theta){
return $x * cos($theta) - $y * sin($theta);
}
function rotateY($x, $y, $theta){
return $x * sin($theta) + $y * cos($theta);
}
I got the above code from a note in php.net
I've created a PHP script to generate an avatar. When I display the image, the dimensions are 250px x 250px. I want to resize at the end (when all the modifications has been done) the avatar before displaying it but I can not find the function.
This is my code :
if(!empty($_GET['pseudo']))

$query1 = $bdd->prepare("SELECT username, user_id, VID FROM phpbb_users LEFT JOIN 0php_users ON 0php_users.phpbb_id = phpbb_users.user_id WHERE username_clean = ?");
$query1->execute(array(strtolower($_GET['pseudo'])));
if($query1->rowCount() == 1)
{
$data1 = $query1->fetch();
$query2 = $bdd->prepare("SELECT nom FROM phpbb_user_group
RIGHT JOIN 0php_hubs ON phpbb_user_group.group_id = 0php_hubs.id_groupe
WHERE user_id = ?");
$query2->execute(array($data1['user_id']));
$data2 = $query2->fetch();
$image = imagecreatefrompng("avatar.png");
$background = imagecolorallocate($image, 0, 0, 0);
imagecolortransparent($image, $background);
imagealphablending($image, false);
imagesavealpha($image, true);
if(($_GET['param']=='ivao')&&(!empty($data1['VID'])))

imagecopy($image, $ivao, 87, 173, 0, 0, 150, 30);
}
$couleur = imagecolorallocate($image, 0, 0, 0);
$largeur_source = imagesx($image);
$fontfile = 'calibri.ttf';
$angle = 0;
$police = 18;
$text_size = imagettfbbox($police, $angle, $fontfile, 'Hub de '.$data2['nom']);
$text_size2 = imagettfbbox($police, $angle, $fontfile, $data1['username']);
$text_width = (($text_size[2] + $text_size[4]) / 2) - (($text_size[0] + $text_size[6]) / 2);
$text_width2 = (($text_size2[2] + $text_size2[4]) / 2) - (($text_size2[0] + $text_size2[6]) / 2);
$x = ($largeur_source - $text_width)/2;
$x2 = (176 - $text_width2)/2 + 74;
$y2 = ($BoolIvao == true)?160:175;
imagettftext($image, $police, $angle, $x2, $y2, $couleur, $fontfile, $data1['username']);

You need to use imagecopyresampled to resize image.

this is the code I always use to resize an image through PHP (I hope it will help you) best wishes:
NOTE: $filetemp refers to your file's temporary name.
Also in this code i'm saving images as a png you can change it to your desired extension
<?php

$new_images = $temporary.".png";
$width=60; //*** Fix Width & Heigh (Autu caculate) ***//
$size=GetimageSize($filetemp);
$height=round($width*$size[1]/$size[0]);
$images_orig = ImageCreateFromJPEG($filetemp);
$photoX = ImagesX($images_orig);
$photoY = ImagesY($images_orig);
$images_fin = ImageCreateTrueColor($width, $height);
ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
imagepng($images_fin,"YourFolder/".$new_images);
ImageDestroy($images_orig);

$x = ($width - $textbox[4])/2;

imagettftext($im, $font, 0, $x, $y, $textcolor, $font_fam , $text) or die('Error in imagettftext function');
// ImageString($im, $font, $position_center, $position_middle, $text, $textcolor);
Imagepng($im);
header("Content-type: image/png");
imagedestroy($im);
The image displays successfully and I need to display border for this image.
You can add ImageRectangle($im, 0, 0, $width - 1, $height - 1, $color); after the variable $textcolor. I think this may help you.
