PHP - Imagepng Not Transparent, Black Background

I have the following I use for uploading images, but I am having an issue with transparent background png images, they all get changed from transparent background to a black background. After doing some hunting around I see I neet to use imagealphablending and imagesavealpha to keep the trransparency, but it doesnt seem to be working I still get the black backgrounds, any ideas?

Here is the script

Code: [Select]
<?php
// Process new logo image
if ($_FILES['logo']['tmp_name']&&$_FILES['logo']['tmp_name']!="") {  
// set memory limit for image
ini_set("memory_limit","32M");
// Check file extension
$checkfile=$_FILES['logo']['name'];
$ext=substr($checkfile, -3);
// Redirect if not correct image type
if (!in_array($ext, array('jpg', 'JPG', 'gif', 'GIF', 'png', 'PNG'))) {
header("Location: ../control_index.php?sponsors=error1");
// Close database connection
mysql_close($link);
exit ();
}
// Create logo image (300px wide)
$file=$_FILES['logo']['tmp_name'];
list($width, $height)=getimagesize($file);
// Scale to width
$main_width=300;
$main_height=$height*($main_width/$width);

if ($ext=="jpg"||$ext=="JPG") {
$image=imagecreatefromjpeg($file);
$newname="sponsor".time().".jpg";
}
if ($ext=="gif"||$ext=="GIF") {
$image=imagecreatefromgif($file);
$newname="sponsor".time().".gif";
}
if ($ext=="png"||$ext=="PNG") {
$image=imagecreatefrompng($file);
$newname="sponsor".time().".png";
}
// Create main image file
$main_image=imagecreatetruecolor($main_width, $main_height);
imagecopyresampled($main_image, $image, 0, 0, 0, 0, $main_width, $main_height, $width, $height);
$cp_file="../images/sponsors/".$newname;
$site_file="../../images/sponsors/".$newname;
if ($ext=="jpg"||$ext=="JPG") {
imagejpeg($main_image, $cp_file, 100);
imagejpeg($main_image, $site_file, 100);
}
if ($ext=="gif"||$ext=="GIF") {
imagegif($main_image, $cp_file, 100);
imagegif($main_image, $site_file, 100);
}
if ($ext=="png"||$ext=="PNG") {
// Turn off alpha blending and set alpha flag
imagealphablending($main_image, false);
imagesavealpha($main_image, true);
imagepng($main_image, $cp_file, 9);
imagepng($main_image, $site_file, 9);
}

Hi,
I'm trying to convert a charting app to  OOP.
So here I've simplified it down to just the bare bones issue of drawing a line to a png image and displaying it.

Code: [Select]

<?php
 class chart {
  var $im;
  var $backgroundColor;
  var $textColor;
  function chart() {
    $this->im= @ImageCreate (100, 200) or die ("Cannot Initialize new GD image stream");
    $this->backgroundColor = ImageColorAllocate ($this->im, 224, 234, 234);
    $this->textColor = ImageColorAllocate($this->im, 233, 14, 91);
  }
 
  function display() {
    imageline ($this->im,0,0,100,200,$this->backgroundColor);
    imageline ($this->im,100,0,0,200,$this->textColor);

    ImagePng ($this->im);
  }
}
?>


Here is the code which instantiates the class.

Code: [Select]
<?php
  include "simple_draw.php";

$mychart = new chart();
$mychart->chart();
$mychart->display();

?>



Basically depending on how I rework it, one of two things happens: a)it generates a bunch of little boxes which say fffd, or b) I get a message saying the resource is invalid or nonexistent (this error isn't coming up right now so I can't be precise.)

If this is run outside the OOP environment it works fine. No sure. I'm really trying to work with classes but this kind of problem is frustrating and admittedly makes it tempting to just go back to regular functions.

Any ideas??

Thanks,
Jeff

I have to do this but i get this error: https://ibb.co/mFzxqXL

can anyone help me?

I have created a image using imagepng() and then right-click'd and saved it. I then added it to the database by using phpMyAdmin to upload it directly into a field called 'avatar' which is a BLOB. The code the view the image back is the following:

header("Content-type: image/png");
echo mysql_result(mysql_query("SELECT `avatar` FROM `rscd_players` WHERE `username` = 'Kryptix'"), 0);

Now when I try and add the imagepng() directly to the database it doesn't work. I've tried multiple things. Here's the code:

ob_start(); imagepng($char_image); $pngimagedata = ob_get_contents(); ob_end_clean();

mysql_query("UPDATE `rscd_players` SET `avatar` = " . $pngimagedata . " WHERE `username` = 'Kryptix'");

Here's the full code: http://pastebin.com/jqsKc9Qd

This is the query that phpMyAdmin produces: http://pastebin.com/nuypNuwJ

This is the query that the above code produces: http://pastebin.com/NPWmi5eb

phpMyAdmin is 2.2kB, my code is 4.4kB

Any idea? I've been trying all night...

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] . '-' . $parts[1] . '-' . $parts[0];

        $row++;

        $import="INSERT into dispatch (delivery_note_number, delivery_date, dispatch_date, customer_delivery_date, delivery_line, produce, variety, quantity, pallets, count, depot, customer, grower, haulier, status) 
        values ('$noQuotes[0]', '$delivery_date', '$noQuotes[2]', '$noQuotes[3]', '$noQuotes[4]', '$noQuotes[5]', '$noQuotes[6]', '$noQuotes[7]', '$noQuotes[8]', '$noQuotes[9]', '$noQuotes[10]', '$noQuotes[11]', '$noQuotes[12]', '$noQuotes[13]', '$noQuotes[14]')";

        echo $import; 
        mysql_query($import) or die(mysql_error());
     }

        //header("location:list_dispatch.php?st=recordsadded");


    fclose($handle);
}

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?

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 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!

imagefill($im,0,0,$tc);

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'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"];

    }
 }

I am using the following code to give my image round corners, but i am using an image that just cuts the corner with a white shape. Is it possible to make it cut the corner with a transparent color?

function roundcorners($image, $topleft, $topright = null, $bottomright = null, $bottomleft = null) {
if($topright == null) $topright = $topleft;
if($bottomright == null) $bottomright = $topleft;
if($bottomleft == null) $bottomleft = $topleft;
if($topleft >= 2) {
$tl = imagecreatefrompng("corner.png");
imagecopyresampled($image, $tl, 0, 0, 0, 0, $topleft, $topleft, 485, 485);
}
if($topright >= 2) {
$tr = imagerotate(imagecreatefrompng("corner.png"), 270, 0);
imagecopyresampled($image, $tr, imagesx($image)-$topright, 0, 0, 0, $topright, $topright, 485, 485);
}
if($bottomright >= 2) {
$br = imagerotate(imagecreatefrompng("corner.png"), 180, 0);
imagecopyresampled($image, $br, imagesx($image)-$bottomright, imagesy($image)-$bottomright, 0, 0, $bottomright, $bottomright, 485, 485);
}
if($bottomleft >= 2) {
$bl = imagerotate(imagecreatefrompng("corner.png"), 90, 0);
imagecopyresampled($image, $bl, 0, imagesy($image)-$bottomleft, 0, 0, $bottomleft, $bottomleft, 485, 485);
}
}

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.
