Creating images question

[cturner01]

I am wondering if someone could please tell me how I could create an image exactly like the attached one using PHP? Also I would like the image to be saved to the server. Thanks in advance.

While waiting for the image to be approved, you will most probably have to use some form of th GD library, check out http://php.net/gd

Using GD's own font selection:

<?php
header("Content-type: image/png");
$im = @imagecreate(200, 23)
    or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 57, 122);
$text_color = imagecolorallocate($im, 255, 255, 255);
imagestring($im, 3, 10, 5,  "ABOUT US", $text_color);
imagepng($im);
imagedestroy($im);
?>

gives the following



play with the imagestring fonts and also look into imagettftext() for antialiased text.

To save the image to the server, modify the imagepng function.

imagepng ($im, "/pics/image.png")

Thanks guys, you have been great. But what happens if I don't want to save the image as a png. I would prefer it to be saved as a gif or jpeg. My GD version is 2.0.28, if that helps.

Change the header to:

header("Content-type: image/jpeg"); 

and the line:
imagepng ($im, "/pics/image.png")

imagejpeg ($im, "/pics/image.jpg")

I am now getting the following error:
<b>Warning</b>: imagejpeg() [<a href='function.imagejpeg'>function.imagejpeg</a>]: Unable to open '/images/aboutusbtn.jpeg' for writing in <b>/home/account/public_html/folder/createimage.php</b> on line <b>10</b><br />. Can someone please help me solve this error?

Post your code please

[cturner01]

ob_start();
header("Content-type: image/jpeg"); 
$im = @imagecreate(200, 23)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 57, 122);
$text_color = imagecolorallocate($im, 255, 255, 255);
imagestring($im, 3, 10, 5,  "ABOUT US", $text_color);
 
imagejpeg ($im, "/images/aboutusbtn.jpeg"); // line 10 is here
 
imagedestroy($im);
ob_end_flush();

OK, using that code it works fine for me. The only thing I changed was the path it was saving to; I removed the /images/ and ran the code.

Check that the folder has write permissions and also - is this going to be used repeatedly for creating buttons on the fly? If so I would consider putting it into a function rather than call it through the browser.

I have made more changes to the code and now it isn't displaying the text on the button. Also it is only saving it as .jpeg. Thanks in advance.

			function makeimage() {
				$button = str_replace(' ', '', $pagetitle);
				header("Content-type: image/jpeg"); 
				$im = @imagecreate(200, 23)
				or die("Cannot Initialize new GD image stream.");
				$background_color = imagecolorallocate($im, 0, 57, 122);
				$text_color = imagecolorallocate($im, 255, 255, 255);
				imagestring($im, 3, 10, 5,  $button, $text_color);
				$button2 = imagejpeg ($im, $button.".jpeg");
				imagedestroy($im);
			}
			makeimage();
