How to combine image and text on the fly in php
i want to combine text and image on the fly to create a jpg widget. I want to do this for a fundraising website, i will need to update the image once a day so it reflect the updated fundraising progress bar. The reason why i want a jpg (开发者_JAVA技巧image) widget is because it is much more friendly to add to blogs, website etc.
you can do it with gd
//open up the image you want to put text over
$im = imagecreatefromjpeg($imagePath);
//The numbers are the RGB values of the color you want to use
$black = ImageColorAllocate($im, 255, 255, 255);
//The canvas's (0,0) position is the upper left corner
//So this is how far down and to the right the text should start
$start_x = 10;
$start_y = 20;
//This writes your text on the image in 12 point using verdana.ttf
//For the type of effects you quoted, you'll want to use a truetype font
//And not one of GD's built in fonts. Just upload the ttf file from your
//c: windows fonts directory to your web server to use it.
Imagettftext($im, 12, 0, $start_x, $start_y, $black, 'verdana.ttf', 'text to write');
//Creates the jpeg image and sends it to the browser
//100 is the jpeg quality percentage
Imagejpeg($im, '', 100);
ImageDestroy($im);
I'd suggest you look into Imagemagick.
