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? saramg
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. michal dot kocarek
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, $color); } ?> administrador ensaimada sphoera punt com
I've made a function to make full color gradients: <?php // The image must be in truecolor mode!! function gradient_region($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 += $inc_red; imagefilledrectangle($img, $x+$i,$y, $x+$i,$y+$height, imagecolorallocatealpha($img, $src_red,$src_green,$src_blue,$src_alpha)); } } ?> More functions at http://www.sphoera.com terereese
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 sdonie
I made some simple additions to the 'ratings bar' example above to allow for different sizes. It also doesn't assume that global GET variables is turned on, and explicitly looks for parameters it needs. ---- <?php // copied from the PHP manual: // http://us3.php.net/manual/en/function.imagefilledrectangle.php //this needs to reside in its own php page //you can include that php page in your html as you would an image: //<IMG SRC="makebar.php?rating=25.2&width=200&height=20" border="0"> // rating is a percentage from 0 to 100. function drawRating($rating) { $width = $_GET['width']; $height = $_GET['height']; if ($width == 0) { $width = 102; } if ($height == 0) { $height = 10; } $rating = $_GET['rating']; $ratingbar = (($rating/100)*$width)-2; $image = imagecreate($width,$height); //colors $back = ImageColorAllocate($image,255,255,255); $border = ImageColorAllocate($image,0,0,0); $red = ImageColorAllocate($image,255,60,75); $fill = ImageColorAllocate($image,44,81,150); ImageFilledRectangle($image,0,0,$width-1,$height-1,$back); ImageFilledRectangle($image,1,1,$ratingbar,$height-1,$fill); ImageRectangle($image,0,0,$width-1,$height-1,$border); imagePNG($image); imagedestroy($image); } Header("Content-type: image/png"); drawRating($rating); ?> ivank
As stated above, it needs to go from the top left corner to the bottom right corner. Just use this to flip it if neccessary: // flip them if neccessary (x3, y3 are temp vars) if($x1 > $x2) { $x3 = $x2; $x2 = $x1; $x1 = $x3; } if($y1 > $y2) { $y3 = $y2; $y2 = $y1; $y1 = $y3; } ImageFilledRectangle($im, $x1, $y1, $x2, $y2, $color); me a.t. forestfactory d.o.t. de
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.

a simple way of using imagerectangle to create a percentage bar <?php //this needs to reside in its own php page //you can include that php page in your html as you would an image: //<IMG SRC="ratingpng.php?rating=25.2" border="0"> function drawRating($rating) { $image = imagecreate(102,10); $back = ImageColorAllocate($image,255,255,255); $border = ImageColorAllocate($image,0,0,0); $red = ImageColorAllocate($image,255,60,75); $fill = ImageColorAllocate($image,44,81,150); ImageFilledRectangle($image,0,0,101,9,$back); ImageFilledRectangle($image,1,1,$rating,9,$fill); ImageRectangle($image,0,0,101,9,$border); imagePNG($image); imagedestroy($image); } Header("Content-type: image/png"); drawRating($rating); ?> spam
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!) /Scarpia <?php Header("Content-type: image/png"); drawRatingBlocks($rating); function drawRatingBlocks($rating) { $rating = $_GET['rating']; $width = $_GET['width']; $height = $_GET['height']; $blocks = $_GET['blocks']; if ($width == 0) $width = 130; if ($height == 0) $height = 13; $spacing = max(1, floor($height/6) ); if ($blocks == 0) $blocks = floor( $width / ($height-2 + $spacing) ); $blockwidth = floor( $width / $blocks ) - $spacing; $short_side = min($height-2, $blockwidth); $blockvalue = 100 / $blocks; $image = ImageCreate($width,$height); $img2 = ImageCreate($width,$height); // Define base colors $back = ImageColorAllocate($image,255,255,255); $blur = ImageColorAllocate($image,230,223,188); $fill = ImageColorAllocate($image,188,182,133); $lightblur = ImageColorAllocate($image,238,235,216); // Would be nice to calculate these dynamically instead $lightfill = ImageColorAllocate($image,221,217,193); // Would be nice to calculate these dynamically instead ImagePaletteCopy($img2,$image); ImageFilledRectangle($image,0,0,$width-1,$height-1,$back); ImageFilledRectangle($img2,0,0,$width-1,$height-1,$back); if ($short_side < 25) $radius = 1; else if ($short_side < 40) $radius = 3; else if ($short_side < 50) $radius = 5; else $radius = floor($height/10); for($i=0;$i<$blocks;$i++) { $startX = ($blockwidth+$spacing)*$i + 1; if ((9 <= $short_side) && ($short_side <= 16)) { ImageFilledRectangle($image, $startX, 1, $startX+$blockwidth-1, $height-2, $lightblur); ImageFilledRectangle($img2, $startX, 1, $startX+$blockwidth-1, $height-2, $lightfill); } ImageRectangleWithRoundedCorners($image, $startX, 1, $startX+$blockwidth-1, $height-2, $radius, $blur); ImageRectangleWithRoundedCorners($img2, $startX, 1, $startX+$blockwidth-1, $height-2, $radius, $fill); } $barwidth = ($rating/100)*$blocks*$blockwidth; $barwidth += floor($barwidth/$blockwidth)*$spacing+1; ImageCopy( $image, $img2, 0, 0, 0, 0, $barwidth, $height ); ImageDestroy($img2); ImagePNG($image); ImageDestroy($image); } 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); } ?> google
