php-gd

问题 I have a PHP script that generates an image with PHP GD. After it generates the image, it saves it, and send this output when called by Ajax: imagejpeg($img_data, 'filename.jpg'); echo '<img src="/filename.jpg.jpg">'; And after that, the image is shown on the page, and everything is fine. But, I don't want to create an image every time. Is there some way that I return by Ajax only $raw_data string and show the image? I tried like this: echo $img_data; But no luck, only thing that is returned

问题 I tried this code from the post, but this code is sending two emails on a single run of file. Email file is sending email two times using php mail function Let me know what i am doing wrong - <?php function mytextoverimage( $mytext ) { $headurl = 'http://dummyimage.com/600x400/ffffee/00d5ff.jpg'; header('Content-type: image/jpeg'); $jpg_image = imagecreatefromjpeg($headurl); $black = imagecolorallocate($jpg_image, 1, 1, 1); $font_path = 'myfont/arial.ttf'; $text = $mytext; imagettftext($jpg

A likely solution could be to find the width of the text and then use half of it taken away from half of the banner width, but I've got no idea about how to do this. I am using PHP-GD and do not want to use anything else I will have to install. imagettftext($img, 14, 0, (468 - ((strlen(

问题 I tried this imagejpeg() php method, but it returns an image to a browser on running the code. However I need a method that returns an image URL so that i can use it in my img tag. Currently i have to use - <img src="siteurl/myphpfile.php" /> but i think its better if the method returns an image handler so that i can use it in my img tag, like - <img src="image.jpg" /> My myphpfile.php is the file that contains the code. Searched many functions at php manuals but no luck, I am also using this

问题 I'm trying to sharpen resized images using this code: imageconvolution($imageResource, array( array( -1, -1, -1 ), array( -1, 16, -1 ), array( -1, -1, -1 ), ), 8, 0); When the transparent PNG image is sharpened, using code above, it appears with a black dot in the upper left corner (I have tried different convolution kernels, but the result is the same).
