In search of dynamically changing quote, saying or all other types of text on an image I came across a code that I have modified to fit my initial usage. This procedure requires two files and short knowledge of PHP. If you are familiar with Trap17's sig rotation code you will understand this procedure very fast.
CODE <?php header("Content-type: image/png"); $image = imagecreatefrompng("../images/sotw_background.png"); //imagecolorallocate($image, R, G, B) in HEX values $font_black = imagecolorallocate($image, 2, 1, 8); $font_blue = imagecolorallocate($image, 25, 0, 255); $List = "name.txt"; $string = trim(file_get_contents($List));; //($image, fontsize, rightindent, downindent, data, txtcolour) imagestring($image, 3, 12, 3, "T17", $font_blue); imagestring($image, 1, 86, 6, "SOTW", $font_black); imagestring($image, 1, 110, 6, $string, $font_black); imagepng($image); imagedestroy($image); ?> Code 2 CODE WINNER - USERNAME For a working demo please refer to #23, #24 and #25 here http://www.trap17.com/forums/index.php?s=&...ndpost&p=222107 Let's break it down. As you can see in Code 1 CODE header("Content-type: image/png"); that HEADER calls for PNG as image type. This is crucial since only PNG images can handle dynamically applied text. CODE $image = imagecreatefrompng("../images/sotw_background.png"); states the location of the background image you are going to use. It looks like this  CODE //imagecolorallocate($image, R, G, B) in HEX values as the remark that I made, the value of color in HEX will determine the text color you choose. I made two to make it as a comparison.$font_black = imagecolorallocate($image, 2, 1, 8); $font_blue = imagecolorallocate($image, 25, 0, 255); CODE $List = "name.txt"; This assigns a SINGLE line characters from file named name.txt. And then assigns to variable name STRING from the opened text file. If you don't want to use external file, you can simply set$string = trim(file_get_contents($List));; CODE $string = "your text 1"; etc. You can even do a random text where$string = "your text 2"; CODE $select = rand(1,7); if($select==1)$string = "text 1"; if($select==2)$string = "text 2"; if($select==3)$string = "text 3"; if($select==4)$string = "text 4"; if($select==5)$string = "text 5"; if($select==6)$string = "text 6"; if($select==7)$string = "text 7"; CODE //($image, fontsize, rightindent, downindent, data, txtcolour) This is where the magic happens. As you can see the position of the text is determined by second two numbers. The first number determines the font size. Instead of preset characters, i.e. T17 and SOTW, you can have $string1, $string2 etc.imagestring($image, 3, 12, 3, "T17", $font_blue); imagestring($image, 1, 86, 6, "SOTW", $font_black); imagestring($image, 1, 110, 6, $string, $font_black); The rest is needed to close up the PNG image and safely project reconstructed new image onto the browser. About the sig rotator reference: By renaming dynamic_sig.php to index.php and placing it under a directory called filename.png (yes directory with extension), you can use your newly created dynamic image in the forum CODE [img]http://source_site/filename.png[/img] This will display the dynamic image as though it's been there all along.One key note is that text is only written within the boundary of an image. So if you are looking for larger image simply make your picture larger in dimension. You can have multiple rows and variable font sizes. |

Great script, but for some reason when I upload it to my ftp and link it to forums it shows up as the dreaded red x. Do you have any ideas why this may be? I can send you my edited PHP file and everything if you need, I just really wanna get this thing working.
EDIT: I apologize, but I already fixed the problem. Thanks again for the script. This post has been edited by sendot: Apr 7 2007, 06:20 PM |

Wow, I was looking all over for a code like this one! I downloaded one once, but it included over 100 php files. which would take 2 hours to download and upload. Now I found a code that has two files and takes up little space!
