[RESOLVED] How to echo a range of colors with php image function

[chrisdee]

Im trying to make a image gradient with GD/PHP but cant make the script work.
Any Tips ?

<?php
# Makes a picture and sets size in pixels
$image  = ImageCreate(600, 300);

# Specifies colors
$background_color = ImageColorAllocate($image, 0, 0, 255);      # 0000FF blue
$text_color       = ImageColorAllocate($image, 255, 255, 255);  # FFFFFF white

# Writes text with the coordinates below
$tekst = "Text using the php image function.";
ImageString($image, 4, 30, 50, "$tekst", $text_color);

# Prints out all the figures and picture and frees memory
header('Content-type: image/png');
ImagePNG($image);
imagedestroy($image);
?>

Iv also tried this, but cant get that to work either.

<?php
# Makes a picture and sets size in pixels
$image  = ImageCreate(600, 300);

# Specifies colors
for($i=0; $i<255; $i++) {
 $background_color = ImageColorAllocate($image, $i, $i, $i);
}

$text_color = ImageColorAllocate($image, 255, 255, 255);

# Writes text with the coordinates below
$tekst = "Text using the php image function.";
ImageString($image, 4, 30, 50, "$tekst", $text_color);

# Prints out all the figures and picture and frees memory
header('Content-type: image/png');
ImagePNG($image);
imagedestroy($image);
?>

Awfully sorry for living in the wrong timezone to answer immediately.

# Specifies colors
for($i=0; $i<255; $i++) {
$background_color = ImageColorAllocate($image, $i, $i, $i);
}

You allocate all these colours, but you only store one of them (the last), and you never draw anything with them. Try doing that.
