(PHP 4, PHP 5)

imagefilledrectangle — Draw a filled rectangle

Opis

bool imagefilledrectangle ( resource $image , int $x1 , int $y1 , int $x2 , int $y2 , int $color )

Creates a rectangle filled with color in the given image starting at point 1 and ending at point 2. 0, 0 is the top left corner of the image.

Parametry

obraz: Zasób obrazu, zwrócony przez jedną z funkcji tworzących obrazy, taką jak imagecreatetruecolor().
x1: x-coordinate for point 1.
y1: y-coordinate for point 1.
x2: x-coordinate for point 2.
y2: y-coordinate for point 2.
color: The fill color. A color identifier created with imagecolorallocate().

Zwracane wartości

Zwraca TRUE w przypadku powodzenia, FALSE w przypadku błędu.

Przykłady

Przykład #1 imagefilledrectangle() usage


<?php
// Create a 55x30 image
$im = imagecreatetruecolor(55, 30);
$white = imagecolorallocate($im, 255, 255, 255);

// Draw a white rectangle
imagefilledrectangle($im, 4, 4, 50, 25, $white);

// Save the image
imagepng($im, './imagefilledrectangle.png');

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);

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 = 'Ühg 0123456789';

    $font_face = dirname(__FILE__).'/verdana.ttf'; // put the file in the same directory

    $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

    $bottom_right_y = $box[3];

    $top_right_x = $box[4];

    $top_right_y = $box[5];

    $top_left_x = $box[6];

    $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);

    $box_h = abs($bottom_left_y) + abs($top_left_y);



// add padding

    $padding_x = 5;

    $padding_y = 5;

    $box_w = $box_w + 2 * $padding_x;

    $box_h = $box_h + 2 * $padding_y;



// origin of the text = baseline of the first char

    $text_x = abs($bottom_left_x) -1 + $padding_x;

    $text_y = $box_h -1 - abs($bottom_left_y) - $padding_y;

    

// mysterious correction for the characters going low like pgjq

    if(abs($bottom_left_y) <= 1) $box_h--;



// create the image

    $img = imagecreatetruecolor($box_w, $box_h);

 

// define some colors

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

    $black = imagecolorallocate($img,0,0,0);

    $lightgrey = imagecolorallocate($img, 200, 200, 200);

    $grey = imagecolorallocate($img,100,100,100);

    $yellow = imagecolorallocate($img, 0xFF, 0xFF, 0x00);

 

// attribute colors

    $font_color =  $black;

    $padding_color =  $lightgrey;

    $background_color =  $yellow;

 

// fill image with background color

    imagefill($img, 0, 0, $background_color);



// fill image with padding color

    imagefilledrectangle($img, 0, 0, $box_w, $padding_y - 1, $padding_color); // top

    imagefilledrectangle($img, 0, 0, $padding_x - 1, $box_h - 1, $padding_color); // left

    imagefilledrectangle($img, 0, $box_h - $padding_y -1, $box_w, $box_h - 1, $padding_color); // bottom

    imagefilledrectangle($img, $box_w - $padding_x, 0, $box_w - 1, $box_h - 1, $padding_color); // right



//write text

imagettftext($img, $font_size, 0, $text_x, $text_y, $font_color, $font_face, $text);



//rotate image

    if ($angle > 0) $img = imagerotate($img, $angle, $white);

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 11-Jul-2006 08:02


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;

            $src_blue += $inc_blue;

            $src_green += $inc_green;

            $src_red += $inc_red;

                $x+$i,$y,         

                $x+$i,$y+$height,

                imagecolorallocatealpha($img,

                $src_red,$src_green,$src_blue,$src_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 01:18


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);
