Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -

Fill patterns
My work life has been quite busy lately and I haven’t had a chance to sit down and blog. I have been touring around London and some parts of the northern England consulting and organizing some training here and there. Luckily I have had the chance to do some work on Imagick and the 2.2.0 beta release is getting closer. The internal structure was completely restructured and broken down into several smaller files. During this time Imagick was adapted to follow the PHP Coding Standards more closely. Still a work in progress
I committed slightly modified version of this example to PHP Manual http://uk.php.net/manual/en/imagick.examples.php page a few days ago. The example illustrates using an image as a part of a named fill pattern. The fill pattern is used to annotate text but the named pattern could also be used to fill any shapes that allow fill to be specified (include circles, ellipses, rectangles, polygons etc etc). The code itself is pretty straight forward : Read the image, create the pattern and use the pattern as a fill.
The ice formations image is from http://www.photoeverywhere.co.uk/west/winterholiday/slides/iceformations5679.htm.
-
< ?php
-
-
/* Create a new imagick object */
-
$im = new Imagick( ’iceformations5679.JPG’ ) ;
-
-
/* Create imagickdraw object */
-
$draw = new ImagickDraw() ;
-
-
/* Start a new pattern called "ice" */
-
$draw->pushPattern( ’ice’ , 0 , 0 , 50 , 50 ) ;
-
-
/* Composite the image on the pattern */
-
$draw->composite( Imagick: :COMPOSITE_OVER, 0, 0, 50, 50, $im ) ;
-
-
/* Close the pattern */
-
$draw->popPattern() ;
-
-
/* Use the pattern called "ice" as the fill */
-
$draw->setFillPatternURL( ’#ice’ ) ;
-
-
/* Set font size to 52 */
-
$draw->setFontSize( 52 ) ;
-
-
/* Annotate some text */
-
$draw->annotation( 5, 50, "Hello World !" ) ;
-
-
/* Create a new canvas and white image */
-
$canvas = new Imagick() ;
-
$canvas->newImage( 310, 70, "white" ) ;
-
-
/* Add black border around the resulting image */
-
$canvas->borderImage( ’black’, 1, 1 ) ;
-
-
/* Draw the ImagickDraw on to the canvas */
-
$canvas->drawImage( $draw ) ;
-
-
/* Set the format to PNG */
-
$canvas->setImageFormat( ’png’ ) ;
-
-
/* Output the image */
-
header( "Content-Type : image/png" ) ;
-
echo $canvas ;
-
?>
And the result is here :

Museum of Multimedia Software, Part 4
20 août 2010, par Multimedia Mike — Software MuseumThis is the last part of the series, at least until some more multimedia software shows up at my favorite thrift shop or the other boneyards I scavenge.
Miscellaneous Multimedia Programs
This set includes the titles Matinee FMV Screensaver, MetaCreations Painter Classic, and Multimedia JumpStart. The second one is likely a creation program. I have no idea what the third one is, while the first title gives me chills just thinking about the implications.
Miscellaneous Creativity Software
Magic Theatre and Microsoft Home : Creative Writer. I think I loaded up the former once to find a very basic animation program. The latter isn’t necessarily multimedia-related but certainly classifies as creative software. It also reminds me of the ad I once spied in Entertainment Weekly magazine during the mid-1990s for a Microsoft music history CD-ROM. MS branched out into all kinds of niches.
More Multimedia Creativity Software
VideoCraft and U-Create Games & Animation. I wager these would be fun to play around with if I had the time.
Showcase CD-ROMs
"What Can You Make ? Showcase 7" from Macromedia and Microsoft Multimedia Pack 10.
Basic Multimedia Software Discs
As a multimedia nerd, these Apple QuickTime and Microsoft Video for Windows discs make me sentimental.
Real Software Collection
Grit your teeth and gaze upon CD-ROM distributions of Real’s software. There is a RealAudio disc back from when Real still called themselves Progressive Networks. "Everything you need to hear the web roar !"
Clips
And a few multimedia clip CD-ROMs, along with a disc that promises to test and tune your MPC setup.
Wrap-Up
I would be remiss if I neglected to mention a few more pieces of multimedia creation software in my collection. First, there’s the Barbie Storymaker. I actually gave that one a go, as you can tragically see from that link. Further, the Taco Bell fast food restaurant chain ran, as one of their many kids meal promotions, a series of 4 simple Comics Constructor CD-ROMs. I played briefly with it here and again during an exploration of XML data formats and the parsing thereof (which the software uses). -
Padding thumbnail with color
I know, it’s been a while since I last blogged. This is because a lot of things are happening in my personal life. I recently relocated to London from Finland and started a new job. Things are quite busy but I will try to post an example now and then. In the meanwhile I would like to hear about sites using Imagick, so if your project is not super secret please post an url and maybe a small explanation what you’re doing with Imagick on the site. This is purely for my personal interest.
Anyway, to the point. Today’s example originates from a question asked by a user. How do I thumbnail the image inside given dimensions proportionally and fill the “blank” areas with a color ? Well, the answer is here
The code is for Imagick 2.1.0 but adapting to older versions should not be hard.
-
< ?php
-
/* Define width and height of the thumbnail */
-
$width = 100 ;
-
$height = 100 ;
-
-
/* Instanciate and read the image in */
-
$im = new Imagick( "test.png" ) ;
-
-
/* Fit the image into $width x $height box
-
The third parameter fits the image into a "bounding box" */
-
$im->thumbnailImage( $width, $height, true ) ;
-
-
/* Create a canvas with the desired color */
-
$canvas = new Imagick() ;
-
$canvas->newImage( $width, $height, ’pink’, ’png’ ) ;
-
-
/* Get the image geometry */
-
$geometry = $im->getImageGeometry() ;
-
-
/* The overlay x and y coordinates */
-
$x = ( $width - $geometry[’width’] ) / 2 ;
-
$y = ( $height - $geometry[’height’] ) / 2 ;
-
-
/* Composite on the canvas */
-
$canvas->compositeImage( $im, imagick: :COMPOSITE_OVER, $x, $y ) ;
-
-
/* Output the image*/
-
header( "Content-Type : image/png" ) ;
-
echo $canvas ;
-
-
?>
