Is it possible to both save and display a created image?

I can display but not save

 

 

<?php
$str2=$_GET['str'];
$str=$_GET['str1'];
$str3="By";
$ourFileName = $_SERVER['DOCUMENT_ROOT'] . '/images/test.png';

$image = ImageCreateFromPNG("http://localhost:8888/wordpress_3/wp-content/plugins/Authors2/jackets/GDL.png");
$color = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
$colorShadow = imagecolorallocate($image, 0x66, 0x66, 0x66);
$font = 'Tahoma.ttf';
$fontSize = "10";
$fontRotation = "0";

/* Shadow str = title */
ImageTTFText($image, $fontSize, $fontRotation, 27, 22, $colorShadow, $font, $str );

/* Top Level */
ImageTTFText($image, $fontSize, $fontRotation, 25, 20, $color, $font, $str);

/*standard narrative*/
ImageTTFText($image, $fontSize, $fontRotation, 25, 60, $color, $font, $str3);

ImageTTFText($image, $fontSize, $fontRotation, 25, 100, $color, $font, $str2);


header("Content-Type: image/PNG");
ImagePng ($image);
imagedestroy($image);
?>

You can use second parameter to save the image like

$path ='images/imagename.png';
ImagePng ($image,$path);

 

also if you want to force download image then use headers

header('Content-Disposition: Attachment;filename=imagename.png');
header('Content-type: image/png');

Thank you.

I can get the image with the text, but when i add the save path the image does not show, just a small question mark in a box.

I cant see where this is going wrong.

My code

is

<?php
$str2=$_GET['str'];
$str=$_GET['str1'];
$str3="By";

$path ='http://localhost:8888/test_upload/images/imagename.png';

$image = ImageCreateFromPNG("http://localhost:8888/wordpress_3/wp-content/plugins/Authors2/jackets/GDL.png");
$color = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
$colorShadow = imagecolorallocate($image, 0x66, 0x66, 0x66);
$font = 'Tahoma.ttf';
$fontSize = "10";
$fontRotation = "0";

/* Shadow str = title */
ImageTTFText($image, $fontSize, $fontRotation, 27, 22, $colorShadow, $font, $str );

/* Top Level */
ImageTTFText($image, $fontSize, $fontRotation, 25, 20, $color, $font, $str);

/*standard narrative*/
ImageTTFText($image, $fontSize, $fontRotation, 25, 60, $color, $font, $str3);

ImageTTFText($image, $fontSize, $fontRotation, 25, 100, $color, $font, $str2);

header('Content-Disposition: Attachment;filename=imagename.png');
header("Content-Type: image/PNG");

ImagePng ($image,$path);

imagedestroy($image);
?>

and the img tag is

echo "<img src='http://localhost:8888/test_upload/image-save.php?str=$str&str1=$str1'/>";

Any advice appreciated.

it looks like you're attempting to save the PNG to $path AND expecting it to get sent to the browser. it's one or the other unless you add a separate line to send image to browser.

 

http://php.net/manual/en/function.imagepng.php

[ansharma]

if you want to display image on browser then remove this line from your code

header('Content-Disposition: Attachment;filename=imagename.png');

 

by removing this code your image will saved at the location you specified and also displayed on browser but it will not downloaded automatically to download image you should right click on image and then coose "save image as " option

[Lassie]

I tried removing the first header and I still have no image.

If I remove the $path I have the image but not saved.

Can I add a seperate line to save it

ImagePng($image);
ImagePng ($image,$path);

[ansharma]

try this code

 

<?php
ob_start();
$str2=$_GET['str'];
$str=$_GET['str1'];
$str3="By";

$path ='http://localhost:8888/test_upload/images/imagename.png';

$image = ImageCreateFromPNG("http://localhost:8888/wordpress_3/wp-content/plugins/Authors2/jackets/GDL.png");
$color = imagecolorallocate($image, 0xFF, 0xFF, 0xFF);
$colorShadow = imagecolorallocate($image, 0x66, 0x66, 0x66);
$font = 'Tahoma.ttf';
$fontSize = "10";
$fontRotation = "0";

/* Shadow str = title */
ImageTTFText($image, $fontSize, $fontRotation, 27, 22, $colorShadow, $font, $str );

/* Top Level */
ImageTTFText($image, $fontSize, $fontRotation, 25, 20, $color, $font, $str);

/*standard narrative*/
ImageTTFText($image, $fontSize, $fontRotation, 25, 60, $color, $font, $str3);

ImageTTFText($image, $fontSize, $fontRotation, 25, 100, $color, $font, $str2);

//header('Content-Disposition: Attachment;filename=imagename.png');
//header("Content-Type: image/PNG");

ImagePng ($image,$path);

imagedestroy($image);


if ($fd = fopen (Path, "r")) 
{
header("Content-Type: image/PNG");
//header("Content-Disposition: attachment; filename=".$n);
//header("Cache-control: private");
 while(!feof($fd)) 
	{
        $buffer = fread($fd, 2048);
        echo $buffer;
	}

}
fclose ($fd);
ob_end_flush();
exit;

?>

Thanks - I tried that and i get a broken image.

Hi Lassie,

if there is any error in my code then don't mind.

[Lassie]

I still cant save the image.

I need it to be automatically saved rather than a forced download as I need the generated image saved to  the server and placed in a user refernced.

For information this is being developed on a mac.

Could you explain what you were intending with the code you posted to read the file please?

if ($fd = fopen (Path, "r")) 
   {
   header("Content-Type: image/PNG");
   //header("Content-Disposition: attachment; filename=".$n);
   //header("Cache-control: private");
    while(!feof($fd)) 
      {
        $buffer = fread($fd, 2048);
        echo $buffer;
      }
   
   }
fclose ($fd);
   ob_end_flush();
   exit;

?>
