php-gd

I'm having troubles when trying to create an image using imagecreatefromjpeg using this Dockerfile to generate the container: FROM php:7.1-apache RUN apt-get update && \ apt-get install -y -qq git \ libjpeg62-turbo-dev \ apt-transport-https \ libfreetype6-dev \ libmcrypt-dev \ libpng12-dev \ libssl-dev \ zip unzip \ nodejs \ npm \ wget \ vim RUN pecl install redis && docker-php-ext-enable redis RUN docker-php-ext-install -j$(nproc) iconv mcrypt zip pdo pdo_mysql gd bcmath COPY ./containers/yii.conf /etc/apache2/sites-available/000-default.conf RUN for mod in rewrite headers; do a2enmod $mod;

I have written a recursive function in PHP to crop text. The cropped text will have ... attached to the end. Non-cropped text will be returned in its original state. It works if the text fits the max width. However, if it does not fit in the given width the function will not return a value but it should. It seems that the whole return statement is ignored. If I replace the return with echo, it shows the correct value. The expected result: -TEST ZIN -TEST ZI -TEST Z -TEST -TES -TE... (nothing is returned here so this will never be shown) function check_length($str, $max, $size = SIZE, $rec =

After updating to Mac OS X 10.10 (Yosemite) and starting Apache with PHP support, everything works as before except for any image operations on PNG files. I get a Call to undefined function imagecreatefrompng() , while any operation on JPEG files work. So GD is present, but not for PNG. There is one line in the phpinfo() that looks like the problem: '--with-png-dir=no' The GD section from phpinfo() : How do I get the included PHP to work with PNG files? Here's another option, from the guys from liip, here . This is a PHP package that comes pre-built for Yosemite (older versions works too) but

What seems to be simple, isn't :( I'm trying to add something like a watermark (transparent png) on an image (jpg). This is the code I'm using: $width = 800; $height = 600; $bottom_image = imagecreatefromjpeg("portrait1.jpg"); $top_image = imagecreatefrompng("man2.png"); imagesavealpha($top_image, true); imagealphablending($top_image, true); imagecopy($bottom_image, $top_image, 200, 200, 0, 0, $width, $height); header('Content-type: image/png'); imagepng($bottom_image); When I merge the images, the png is positioned at the right place, everythig above and left of it is good (jpg is copied),

Here is an example what I would like to do: Here is the result: function red_rectangle($img_src,$x1,$y1,$x2,$y2,$tr = 50) { // Load image $img = imagecreatefromjpeg($img_src); // Transparent red $red = imagecolorallocatealpha($img, 255, 0, 0, $tr); // Draw a white rectangle imagefilledrectangle($img, $x1, $y1, $x2, $y2, $red); // Save the image (overwrite) imagejpeg($img, $img_src); imagedestroy($img); } You need to use http://php.net/manual/en/function.imagefilledrectangle.php , passing a color created with http://www.php.net/manual/en/function.imagecolorallocatealpha.php . As you can see,
