Example #1 Outputting a WBMP image <?php // Create a blank image and add some text $im = imagecreatetruecolor(120, 20); $text_color = imagecolorallocate($im, 233, 14, 91); imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color); // Set the content type header - in this case image/vnd.wap.wbmp // Hint: see image_type_to_mime_type() for content-types header('Content-Type: image/vnd.wap.wbmp'); // Output the image imagewbmp($im); // Free up memory imagedestroy($im); ?> Example #2 Saving the WBMP image <?php // Create a blank image and add some text $im = imagecreatetruecolor(120, 20); $text_color = imagecolorallocate($im, 233, 14, 91); imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color); // Save the image imagewbmp($im, 'simpletext.wbmp'); // Free up memory imagedestroy($im); ?> Example #3 Outputting the image with a different foreground <?php // Create a blank image and add some text $im = imagecreatetruecolor(120, 20); $text_color = imagecolorallocate($im, 233, 14, 91); imagestring($im, 1, 5, 5, 'A Simple Text String', $text_color); // Set the content type header - in this case image/vnd.wap.wbmp // Hint: see image_type_to_mime_type() for content-types header('Content-Type: image/vnd.wap.wbmp'); // Set a replacement foreground color $foreground_color = imagecolorallocate($im, 255, 0, 0); imagewbmp($im, NULL, $foreground_color); // Free up memory imagedestroy($im); ?> NOTES

imagelayereffect - Set the alpha blending flag to use the bundled libgd layering effects

SYNOPSIS
bool imagelayereffect (resource $image, int $effect) DESCRIPTION
Set the alpha blending flag to use the bundled libgd layering effects. PARAMETERS
o $ image -An image resource, returned by one of the image creation functions, such as imagecreatetruecolor(3). o $effect - One of the following constants: o IMG_EFFECT_REPLACE - Use pixel replacement (equivalent of passing TRUE to imagealphablending(3)) o IMG_EFFECT_ALPHABLEND - Use normal pixel blending (equivalent of passing FALSE to imagealphablending(3)) o IMG_EFFECT_NORMAL - Same as IMG_EFFECT_ALPHABLEND. o IMG_EFFECT_OVERLAY - Overlay has the effect that black background pixels will remain black, white background pixels will remain white, but grey background pixels will take the colour of the foreground pixel. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 imagelayereffect(3) example <?php // Setup an image $im = imagecreatetruecolor(100, 100); // Set a background imagefilledrectangle($im, 0, 0, 100, 100, imagecolorallocate($im, 220, 220, 220)); // Apply the overlay alpha blending flag imagelayereffect($im, IMG_EFFECT_OVERLAY); // Draw two grey ellipses imagefilledellipse($im, 50, 50, 40, 40, imagecolorallocate($im, 100, 255, 100)); imagefilledellipse($im, 50, 50, 50, 80, imagecolorallocate($im, 100, 100, 255)); imagefilledellipse($im, 50, 50, 80, 50, imagecolorallocate($im, 255, 100, 100)); // Output header('Content-type: image/png'); imagepng($im); imagedestroy($im); ?> The above example will output something similar to:[NOT DISPLAYABLE MEDIA]Output of example : imagelayereffect() NOTES
