Not getting image output #38
Comments
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 $pinguLayer->getWidth(); and now it works |
ini_set('display_errors', 'On');error_reporting(E_ALL); require_once(DIR.'/PHPImageWorkshop/ImageWorkshop.php'); //var_dump(file_exists('PHPImageWorkshop/banner1.jpg'));// breaks the $layer=ImageWorkshop::initFromPath('PHPImageWorkshop/banner1.jpg'); $layer->resizeInPixel(400, null, true); $image = $layer->getResult(); you can't have echos or var_dump in a picture file it don't work you could On Tue, Apr 8, 2014 at 12:59 PM, chrbono notifications@github.com wrote:

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.
