Neither of those worked, but I tried taking out another part, and it's working now!Thanks for all your guys' help!

Sorry, I should have been more clear.After adding in the debug code, I discovered the problem and fixed it.I now get the properly generated text, but the text/image still has the black background.

I added in the transparency code, ending up with <?$x = 0;$text=$_GET["text"];$im = imagecreatetruecolor( 20*strlen($text), 20 );imagealphablending( $im, false );$col = imagecolorallocate( $im, 0, 0, 0, 127 );imagefilledrectangle( $im, 0, 0, 20*strlen($text), 20, $col );imagealphablending( $im, true );for ($i = 0; $i < strlen($text); ++$i){$letter = $text[$i];$filename = "http://www.habbground.com/goodies/letters/$letter.png";$image = imagecreatefromPNG($filename);imagecopyresampled($im, $image, $x, 0, 0, 0, 20, 20, 20, 20);$x = $x+20;}header('Content-type: image/png');imagealphablending( $im, false );imagesavealpha( $im, true );imagePNG($im);imageDestroy($im);?> And it still has a black background.

It should be working... outputting the variables returnedtext: ABCDEletter: Afilename: http://www.habbground.com/goodies/letters/A.pngletter: Bfilename: http://www.habbground.com/goodies/letters/B.pngletter: Cfilename: http://www.habbground.com/goodies/letters/C.pngletter: Dfilename: http://www.habbground.com/goodies/letters/D.pngletter: Efilename: http://www.habbground.com/goodies/letters/E.pngCopy/pasting the links returns an image.

<?$x = 0;$text=$_GET["text"];$im = imagecreatetruecolor( 20*strlen($text), 20 );for ($i = 0; $i < strlen($text); ++$i){$letter = $text[$i];$filename = "http://www.habbground.com/goodies/letters/$letter.png";$image = imagecreatefromPNG($filename);imagecopyresampled($im, $image, $x, 0, 0, 0, 20, 20, 20, 20);$x = $x+20;}header('Content-type: image/png');imagePNG($im);imageDestroy($im);?> Returns a totally black image (varying in size depending on the # of letters inputted).

I know WHY its black, i just need to know how to change it.Although it would be ok if the user could simply input a background color (in hex), it would be much better if there was a way to make the image transparent.

Works now, but how do i change the background color so its transparent instead of black?

hehe, backwards it is...Well now that those two things are fixed, all I'm getting is a black box...http://www.habbground.com/txtst.php?text=ABCDE

Alright, changed it to <?0 = $x;$text=$_GET["text"];for ($i = 0; $i < strlen($text); ++$i){$letter = $text{$i};$filename = "/goodies/letters/$letter.gif";$im = imagecreatetruecolor(20, 20);$image = imagecreatefromGIF($filename);imagecopyresampled($im, $image, $x, 0, 0, 0, 20, 20, 20, 20);$x = $x+20;}header('Content-type: image/gif');imageGIF($im);imageDestroy($im);?> and it doesn't output anything.What am I missing (most likely something really obvious)?

But in imagecopyresampled, $width is in the destniation image width spot, so wouldn't you want the width of the destination img increase by 20 for each additional letter?

So far i've got: <?$width = 20;$height = 20;$text=$_GET["text"];for ($i = 0; $i < strlen($text); ++$i){$letter = $text{$i};$filename = "/goodies/letters/$letter.gif";$x = $width-20;$im = imagecreatetruecolor($width, 20);$image = imagecreatefromGIF($filename);imagecopyresampled($im, $image, $x, 0, 0, 0, $width, 20, 20, 20);$width = $width+20;}header('Content-type: image/gif');imageGIF($im);imageDestroy($im);?> But to no avail...All I get is a big black box (good thing is that it changes by 20 pixels for every letter you have)PS- Each source image is 20x20.View- clickyI tried removing $im = imagecreatetruecolor($width, 20); but that just returned http://www.habbground.com/txtst.php?text=ABCDE

Okay, but say the user inputs "Blue"How would I make it so each letter of the variable (that blue is stored in) gets added to the image, and how would i make sure the image is the right size, no matter how many letter there are?

But how do you merge multiple images with imagecopyresampled?All I can see on the reference page is manipulating one image, and copying it to a new file.

Yes, the png file is in the right spot...Strange as it may sound, it's now working, I tried it before adding in the buffer stuff, and it worked :)Anyways, how would I go about making it so the user inputs two colors, and both colors in the image are changed?Finally (rather off-topic), my other question, is there a way to have a text generator where if the user inputs ABC, one image is generated using the images a.png, b.png, and c.png? (I know the answer is yes, I just don't know how)

Good news- No longer displays an error.Bad news- only displays "http://www.habbground.com/hbt.php?color=FFFFFF&color2=000000&submit=Submit"

I still get the same thing after removing<html><head><title>Test 2</title></head><body></body>and</html>

Current code- <html><head><title>Test 2</title></head><body><?PHPini_set("display_errors", 1);error_reporting(E_ALL);$phpHex = '525d63';$phpColor = hex2int($phpHex);$newColor = hex2int(validHexColor($_REQUEST['color'],$phpHex));$im = imageCreateFromPNG('img.png');$phpCIndex = imageColorExact($im,$phpColor['r'],$phpColor['g'],$phpColor['b']);imageColorSet($im,$phpCIndex,$newColor['r'],$newColor['g'],$newColor['b']);header('Content-type: image/png');if ($im = imageCreateFromPNG('img.png')) echo 'OK';else echo 'FALSE';imagePNG($im);imageDestroy($im); /** * @param $hex string 6-digit hexadecimal color * @return array 3 elements 'r', 'g', & 'b' = int color values * @desc Converts a 6 digit hexadecimal number into an array of * 3 integer values ('r' => red value, 'g' => green, 'b' => blue) */function hex2int($hex) { return array( 'r' => hexdec(substr($hex, 0, 2)), // 1st pair of digits 'g' => hexdec(substr($hex, 2, 2)), // 2nd pair 'b' => hexdec(substr($hex, 4, 2)) // 3rd pair );}/** * @param $input string 6-digit hexadecimal string to be validated * @param $default string default color to be returned if $input isn't valid * @return string the validated 6-digit hexadecimal color * @desc returns $input if it is a valid hexadecimal color, * otherwise returns $default (which defaults to black) */function validHexColor($input = '000000', $default = '000000') { // A valid Hexadecimal color is exactly 6 characters long // and eigher a digit or letter from a to f return (eregi('^[0-9a-f]{6}$', $input)) ? $input : $default;}?></body></html> Which, after sending FFFFFF and 000000 for the colors gives me "The image “http://www.habbground.com/hbt.php?color=FFFFFF&color2=000000&submit=Submit” cannot be displayed, because it contains errors."

Nope....

Sorry for the delay...Anyways, yes its in the same directory as the image.Adding if ($im = imageCreateFromPNG('img.png')) echo 'OK';else echo 'FALSE'; changed absolutely nothing.

Neither worked.First solution changed nothing.Changing to text/html only made the error go away. The image didn't get shown.

I'm using firefox, and thats all I'm getting.

Hey guys, I'm having some problems with image manipulation...I have a script where you type in a hex color into a form, you hit send, and then tall of once color of in the image is changed to the color that was inputed. <?PHP$phpHex = '525d63';$phpColor = hex2int($phpHex);$newColor = hex2int(validHexColor($_REQUEST['color'],$phpHex)) ;$im = imageCreateFromPNG('img.png');$phpCIndex = imageColorExact($im,$phpColor['r'],$phpColor['g'],$phpColor['b']);imageColorSet($im,$phpCIndex,$newColor['r'],$newColor['g'],$newColor['b']);header('Content-type: image/png');imagePNG($im);imageDestroy($im); /** * @param $hex string 6-digit hexadecimal color * @return array 3 elements 'r', 'g', & 'b' = int color values * @desc Converts a 6 digit hexadecimal number into an array of * 3 integer values ('r' => red value, 'g' => green, 'b' => blue) */function hex2int($hex) { return array( 'r' => hexdec(substr($hex, 0, 2)), // 1st pair of digits 'g' => hexdec(substr($hex, 2, 2)), // 2nd pair 'b' => hexdec(substr($hex, 4, 2)) // 3rd pair );}/** * @param $input string 6-digit hexadecimal string to be validated * @param $default string default color to be returned if $input isn't valid * @return string the validated 6-digit hexadecimal color * @desc returns $input if it is a valid hexadecimal color, * otherwise returns $default (which defaults to black) */function validHexColor($input = '000000', $default = '000000') { // A valid Hexadecimal color is exactly 6 characters long // and eigher a digit or letter from a to f return (eregi('^[0-9a-f]{6}$', $input)) ? $input : $default ;}?> For some reason, whenever you hit submit, you get the message "The image “http://www.mysite.com/hbt.php?color=[yourcolor]” cannot be displayed, because it contains errors." Where [yourcolor] is replaced by the color you inputed.Any ideas on whats wrong?Also, how would I make it so the user inputs two colors, and two colors on the image are changed?Finally, is there a way to have a text generator, where if the user inputs ABC, one image is generated, using the images a.png, b.png, and c.png? (I know the answer is yes, i just dont know how )Thanks!!
