Description:
------------
I tried generating caption text image with transparent background.

Reproduce code:
---------------
<?php
$image_width = 200;
$image_height = 200;
$text = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
		 Mauris lectus mi, mattis non, euismod vel, sagittis nec, ipsum.";
$im = new Imagick();

$im->newPseudoImage( $image_width, $image_height, "caption:" . $text );
$im->setImageVirtualPixelMethod(Imagick::VIRTUALPIXELMETHOD_TRANSPARENT);
$im->setImageMatte(true);
$im->borderImage( 'black', 1, 1 );
$im->colorizeImage('#FF0000',0.3);
$im->setImageFormat( "png") ;
header( "Content-Type: image/png" );
echo $im;


Expected result:
----------------
Transparent background with red text and red border

Actual result:
--------------
solid white background with red text and red border

Try calling:

$im->setBackgroundColor("transparent");

before the newPseudoImage call. Does it help?

Now it's showing a solid red background. I need it to have a transparent background with red text.

Sorry, but your problem does not imply a bug in PECL itself.  For a
list of more appropriate places to ask for help using PECL, please
visit http://pecl.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PECL.

<?php
$image_width = 200;
$image_height = 200;
$text = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
                 Mauris lectus mi, mattis non, euismod vel, sagittis nec, ipsum.";
$im = new Imagick();
$im->setBackgroundColor("transparent");
$im->newPseudoImage( $image_width, $image_height, "caption:" . $text );
$im->paintOpaqueImage ("black", "red", 100000);

$im->setImageFormat( "png") ;
header( "Content-Type: image/png" );
echo $im;
