Tech Imagemagick Question - GoFuckYourself.com

Publisher Bucks · 02-10-2022, 11:48 AM

This code is working fine, however, when I right click on the image to save it, it doesnt have a .jpg extension, any idea why?

I have the header and extension in the code which should be enough to render it as a .jpg shouldnt it?

<?php
/* Create some objects */
$image = new Imagick();
$draw = new ImagickDraw();
$draw1 = new ImagickDraw();
$draw2 = new ImagickDraw();
$draw3 = new ImagickDraw();
$draw4 = new ImagickDraw();
$pixel = new ImagickPixel( '#0076a3' );

/* New image */
$image->newImage(2000, 3000, $pixel);

$rect = [
'x' => 175,
'y' => 1850,
'h' => 1000,
'w' => 1650,
];

// Draw a Region-of-interest for reference.
$roi = new ImagickDraw();
$roi->setFillColor('#292b2a');
$roi->rectangle($rect['x'],
$rect['y'],
$rect['x'] + $rect['w'],
$rect['y'] + $rect['h']);
$image->drawImage($roi);

$rect = [
'x' => 0,
'y' => 0,
'h' => 75,
'w' => 2000,
];

// Draw a Region-of-interest for reference.
$roi = new ImagickDraw();
$roi->setFillColor('#292b2a');
$roi->rectangle($rect['x'],
$rect['y'],
$rect['x'] + $rect['w'],
$rect['y'] + $rect['h']);
$image->drawImage($roi);

/* Text Color */
$draw->setFillColor('#FFFFFF');

/* Font properties */
$draw->setFont('Bookman-DemiItalic');
$draw->setFontSize( 110 );

/* Text Color */
$draw1->setFillColor('#0076a3');

/* Font properties */
$draw1->setFont('Bookman-DemiItalic');
$draw1->setFontSize( 200 );

/* Text Color */
$draw2->setFillColor('#FFFFFF');

/* Font properties */
$draw2->setFont('Bookman-DemiItalic');
$draw2->setFontSize( 75 );

/* Text Color */
$draw3->setFillColor('#FFFFFF');

/* Font properties */
$draw3->setFont('Bookman-DemiItalic');
$draw3->setFontSize( 75 );

/* Text Color */
$draw4->setFillColor('#0076a3');

/* Font properties */
$draw4->setFont('Bookman-DemiItalic');
$draw4->setFontSize( 60 );

/* Create text */
$image->annotateImage($draw, 220, 2050, 0,
'Text');

/* Create text */
$image->annotateImage($draw1, 370, 2250, 0,
'Text');

/* Create text */
$image->annotateImage($draw2, 225, 2375, 0,
'Text');

/* Create text */
$image->annotateImage($draw3, 600, 2475, 0,
'Text');

/* Create text */
$image->annotateImage($draw4, 575, 2750, 0,
'Text');

/* Give image a format */
$image->setImageFormat('jpg');

/* Output the image with headers */
header('Content-type: image/jpg');
echo $image;?>

Also, im trying to overlay an image on top of the main body, I have tried the code below but it does not seem to be working, is there a better way of achieving it?

Quote:

/* Overlay image */
$image->readImage('watermark.png'), 2000, 1500, 0,
$image->setImageAlpha(0.5);
$image->compositeImage($wm, Imagick::COMPOSITE_OVER, 0, 0);
$image->writeImage('final.jpg');

Thanks for any assistance or pointers you can give

try

header('Content-Disposition: attachment; filename="whatever.jpg"');

Doing a church sign generator? I used to love those.

I can't test the code since it uses "imagick", some php extension, but unless there's a reason you have to use that, look into PHP's "imagecreate" function.

And unless you have to use PHP, you can do this kind of stuff with just Javascript and canvas.

Edit: I bothered to RTFM on the "Imagick" github when I was about to close the tab and it's in the Debian repo, so I tried it. Right clicking and saving in Firefox provides the extension, though it's .jpeg, not .jpg, ie "page.php.jpeg".

Awesome, that worked perfectly, thanks man

Any idea about the image overlay / watermark thing?

*edit* How do I stop the whatever.jpg auto downloading on page load?

One more issue I just discovered...

Quote:

/* Font properties */
$draw4->setFont('Bookman-DemiItalic');
$draw4->setFontSize( 60 );
$draw4->setGravity(Imagick::GRAVITY_CENTER );

Isn't centering the text, any clues as to why?

I've honestly never used imagemagick from php like that, only from command line.
What about a rewriterule so the image URL ends in .jpg?
line1|line2|line3.jpg or something.
