Not getting image output

[chrbono]

Hi, I am a beginner using php, I am getting no image display. I did the test script and it seems that everything is OK, but actually I am doing something wrong because it is not working. This is my code.

'; var_dump(class_exists('PHPImageWorkshop\ImageWorkshop')); echo'
'; $layer=ImageWorkshop::initFromPath('PHPImageWorkshop/banner1.jpg'); var_dump(get_class($layer)); // test echo $layer->getWidth(); echo $layer->getHeight(); $layer->resizeInPixel(400, null, true); $image = $layer->getResult(); header('Content-type: image/jpeg'); imagejpeg($image, null, 95); // We chose to show a JPG with a quality of 95% ?>

I am getting a thumbnail with no image. If I comment the last 3 lines this is the result.

bool(true)
bool(true)
string(40) "PHPImageWorkshop\Core\ImageWorkshopLayer" 1000221

Can someone help? Tell me what I am doing wrong.

I have tried another code as showed in the tutorial and it saves the image edited in a folder, that works beautiful. But what I am getting is a blank thumbnail. I would like that the image is displayed on the web browser to let the user view the image before save. this is my code.

getWidth(); echo'
'; echo $pinguLayer->getHeight(); echo'
'; echo $pinguLayer->getWidth(); echo'
'; echo $pinguLayer->getHeight(); echo'
'; $wwfLogoLayer = ImageWorkshop::initFromPath('images/Google-icon.jpg'); $tuxLayer = ImageWorkshop::initFromPath('images/Mylogolow.gif'); $tuxLayer->resizeInPixel(100, null, true); // resize pingu layer $pinguLayer->resizeInPixel(400, null, true); // Add 2 layers on pingu layer $pinguLayer->addLayerOnTop($wwfLogoLayer, 20, 10, 'LB');//LB== Left bottom $pinguLayer->addLayerOnTop($tuxLayer, 20, 10, 'RT');//RT = Right Top // Saving the result $dirPath =" ImageworkshopUploads"; $filename = "pingu_edited.png"; $createFolders = true; $backgroundColor = null; // transparent, only for PNG (otherwise it will be white if set null) $imageQuality = 95; // useless for GIF, usefull for PNG and JPEG (0 to 100%) $pinguLayer->save($dirPath, $filename, $createFolders, $backgroundColor, $imageQuality); $image = $pinguLayer->getResult(); //header('Content-Length: '.filesize($image)); header("Content-type: image/jpeg"); //print file_get_contents($image); imagejpeg($image, null, 95); // We chose to show a JPG with a quality of 95% ?>

I found what was wrong. I removed

echo $pinguLayer->getWidth();
echo'';
echo $pinguLayer->getHeight();
echo'';

echo $pinguLayer->getWidth();
echo'';
echo $pinguLayer->getHeight();
echo'';

and now it works

ini_set('display_errors', 'On');error_reporting(E_ALL);

require_once(DIR.'/PHPImageWorkshop/ImageWorkshop.php');
use PHPImageWorkshop\ImageWorkshop;

//var_dump(file_exists('PHPImageWorkshop/banner1.jpg'));// breaks the
header output log it elsewhere using a file logger
//var_dump(class_exists('PHPImageWorkshop\ImageWorkshop'));// breaks the
header output log it elsewhere using a file logger

$layer=ImageWorkshop::initFromPath('PHPImageWorkshop/banner1.jpg');
//var_dump(get_class($layer)); // breaks the header output log it elsewhere
using a file logger
//echo $layer->getWidth();// breaks the header output log it elsewhere
using a file logger
//echo $layer->getHeight();// breaks the header output log it elsewhere
using a file logger

$layer->resizeInPixel(400, null, true);

$image = $layer->getResult();
header('Content-type: image/jpeg');
imagejpeg($image, null, 95); // We chose to show a JPG with a quality of 95%

you can't have echos or var_dump in a picture file it don't work you could
try throwing exceptions on errors so you would know if something fail by
visual output when it is rendered in a broswer but that would be the only
way, or have to scripts files on test file the other the production file

//Test.php:

getWidth(); echo $layer->getHeight(); ?>

//Production_file.php:

resizeInPixel(400, null, true); $image = $layer->getResult(); if(!isset($Test)){// if this file is loaded by test.php then $test will be set. header('Content-type: image/jpeg'); imagejpeg($image, null, 95); // We chose to show a JPG with a quality of 95% } Just to note the best way to do this is to make 2 classes on the logic and one the test and then us methods etc to test the system. please read up on Test Driven Development
