Imagecreatetruecolor() PHP Function

Imagecreatetruecolor() PHP Function The imagecreatetruecolor() function is used in PHP to create a new true color image using the GD Library. True color uses a 24-bit color depth when displaying an RGB image. Its two parameters are the width and height of the image you are creating. Sample Code Using Imagecreatetruecolor() Function This code generates a PNG image that is 130 pixels wide by 50 pixels high. The imagecreatetruecolor() function specifies a shape that is 130 pixels wide by 50 pixels high. The text color is set using RGB values. The text that will print on the shape is A Simple Text String, in size 1 (of 1-5) with an x ordinate of 5 and a y-ordinate of 5. Return Values When successful, this function returns an image identifier that represents a black image of the specified size. If not successful, it returns False. Considerations The GD library must be enabled for this function to work properly; otherwise, the return value is False. It can be downloaded free from the internet if you dont already have it installed.
