It looks like there are waves beetween the points, but it's straight.

<?php
$maxwert = 300;
$size = 10;
$img = imagecreatetruecolor($maxwert, $maxwert);
imagecolorallocate($img, 0, 0, 0);

   for($y=0;$y<$maxwert;$y += $size){
     for($x=0;$x<$maxwert;$x+=$size){
      $r = rand(0,255);
      $g = rand(0,255);
      $b = rand(0,255);
      $color = imagecolorallocate($img, $r, $g, $b);
     
      imagefilledrectangle ($img, $x, $y, $x+$size ,$y+$size, $color);
    
     }
   }                 
header("Content-type: image/png");
imagepng($img);

That script draws Serpinski's carpet:

<?php
    set_time_limit(5);

    $i = 4;        // Iterations
    $xy = 500;    // Picture size

    $img = imagecreatetruecolor($xy, $xy);

    $white = imagecolorallocate($img, 255, 255, 255);

    drawCarpet(0, 0, $xy, $xy, $i);
    function drawCarpet($a, $b, $c, $d, $n) {
        global $img, $white;

        if($n <= 0) return;

        $a1 = 2 * $a / 3 + $c / 3;
        $c1 = $a / 3 + 2 * $c / 3;
        $b1 = 2 * $b / 3 + $d / 3;
        $d1 = $b / 3 + 2 * $d / 3;

The examples in function imagettfbbox() gave me many problems because of misunderstand of how the text is positionned in the box.

So I did a new example:
- writing a text
- in the correct position in its box
- with a padding around

Enjoy !
Mike

<?

// some settings
    $angle = 0;
    $text = '?hg 0123456789';

    $font_size = 9; //(int) pixels in GD 1, or points in GD 2

// retrieves box frame
    $box = imagettfbbox($font_size, 0, $font_face, $text);
    $bottom_left_x = $box[0]; // used below
    $bottom_left_y = $box[1]; // used below
    $bottom_right_x = $box[2]; // used below

    $top_right_y = $box[5];

    $top_left_y = $box[7]; // used below

// define width and height of the text box
    $box_w = abs($bottom_left_x) + abs($bottom_right_x);

// add padding
    $padding_x = 5;
    $padding_y = 5;

Thanks terereese. it took me over two hours to figure that one out.
it worked locally: imagefilledrectangle(imagresource, int x1, int x2, int y1, inty2, color)

BUT remote on my provider only this worked: imagefilledrectangle(imagresource, int x1, int y2, int x1, inty1, color)

Any ideas why and where?

terereese at hotmail dot com (12-Jul-2006 04:02)

I would like to inform developers about a problem I encountered when trying to use imagefilledrectangle.

I noted that the order in which the start and end y coordinates are listed is extremely important.
as in the statements below.
if($this->d_values[$i]['unit_value'] < 0)
imagefilledrectangle($this->img,$position_x, $start_y , $end_x, $end_y ,$d_color);           
else               
imagefilledrectangle($this->img, $position_x,$ end_y , $end_x, $start_y,$d_colour);           
           

Thanks

I've made a function to make full color gradients:

<?php

// The image must be in truecolor mode!!
    function gradient_region($img, $x, $y, $width, $height,$src_color, $dest_color=0){
        $src_alpha = ($src_color) >> 24;
        $src_red = ($src_color & 0xFF0000) >> 16;
        $src_green = ($src_color & 0x00FF00) >> 8;
        $src_blue = ($src_color & 0x0000FF);
       
        $dest_alpha = ($dest_color) >> 24;
        $dest_red = ($dest_color & 0xFF0000) >> 16;
        $dest_green = ($dest_color & 0x00FF00) >> 8;
        $dest_blue = ($dest_color & 0x0000FF);
           
           
        $inc_alpha = ($dest_alpha - $src_alpha) / $width;
        $inc_red = ($dest_red - $src_red)/$width;
        $inc_green = ($dest_green - $src_green)/$width;
        $inc_blue = ($dest_blue - $src_blue)/$width;
       
        // If you need more performance, the step can be increased
        for ($i=0;$i<$width;$i++){
            $src_alpha += $inc_alpha;

A different kind of rating bar, using michal's rounded corners function :) I saw this type of rating bar somewhere and thought it looked cool, so the 'design' is a complete ripoff.

Also, note that it scales quite well, from tiny 3x3 pixel dots to huge 300x300 pixel blocks. (Man am I proud of this thing.. well, enjoy!)

As of PHP 5, it seems to be no longer necessary to draw the rectangle from the upper left to the lower right corner. This led me into big trouble porting a script developed under PHP 5 to PHP 4.

michal dot kocarek at seznam dot cz (30-May-2004 09:18)

If you want to draw a rectangle with rounded corners, you can use this simple function...
Rectangle starts at x1y1 and ends at x2y2. $radius defines radius of circled corner.

<?

function ImageRectangleWithRoundedCorners(&$im, $x1, $y1, $x2, $y2, $radius, $color) {
// draw rectangle without corners
imagefilledrectangle($im, $x1+$radius, $y1, $x2-$radius, $y2, $color);
imagefilledrectangle($im, $x1, $y1+$radius, $x2, $y2-$radius, $color);
// draw circled corners
imagefilledellipse($im, $x1+$radius, $y1+$radius, $radius*2, $radius*2, $color);
imagefilledellipse($im, $x2-$radius, $y1+$radius, $radius*2, $radius*2, $color);
imagefilledellipse($im, $x1+$radius, $y2-$radius, $radius*2, $radius*2, $color);
imagefilledellipse($im, $x2-$radius, $y2-$radius, $radius*2, $radius*2, $color);
}

?>

As stated above, it needs to go from the top left corner to the bottom right corner. Just use this to flip it if neccessary:

// flip them if neccessary (x3, y3 are temp vars)
if($x1 > $x2) { $x3 = $x2; $x2 = $x1; $x1 = $x3; }
if($y1 > $y2) { $y3 = $y2; $y2 = $y1; $y1 = $y3; }
ImageFilledRectangle($im, $x1, $y1, $x2, $y2, $color);

Important quirk to note:

While imagerectangle will allow you to use a different order of your coordinates (such as bottom-left to upper-right), imagefilledrectangle will only work correctly if you use top-left to bottom-right as indicated in the docs.
