If you are a Linux user you surely know Tux, for those who don't know him he is a cute little penguin that serves as the Linux mascot. Some years ago the KDE team added SVG support, a little bit later an amazing desktop theme appeared (I think Everaldo was the main author, correct me if I'm wrong), and with it came a redesigned Tux. Nowadays you may find similar themes for Windows including a plethora of customized Tuxes to be used as icons and/or avatars.

The following is my attempt to emulate (note the emphasis) the redesigned Tux with GraphicsBuilder, here goes



Not bad eh? something tells me I should stick with programming and skip drawing...

The code to is a little bit verbose but here are the meat & bones, once the basic shapes & paths have been defined the following code will assemble my version of Tux
def darkOrange = ColorCache.getInstance().getColor('darkOrange') def darkerOrange = darkOrange.darker() renderingHint( key: 'antialiasing', value: 'antialias on' ) ellipse( cx: 90, cy: 180, radiusx: 35, radiusy: 10, id: 'leftFoot' borderColor: darkerOrange, borderWidth: 2, fill: 'darkOrange' ) ellipse( cx: 160, cy: 180, radiusx: 35, radiusy: 10, id: 'rightFoot' borderColor: darkerOrange, borderWidth: 2, fill: 'darkOrange' ) draw( outerBody ){ gradientPaint( x1: 0, x2: 0, y1: 0, y2: 50, color1: 'darkGray', color2: 'black' ) transformations{ translate( x: 41, y: 20 ) } } draw( innerBody, borderColor: false, fill: 'white' ){ transformations{ translate( x: 60, y: 20 ) } } ellipse( cx: 98, cy: 64, radiusx: 5, radiusy: 7, borderColor: false, fill: 'black', id: 'leftEye' ) ellipse( cx: 148, cy: 64, radiusx: 5, radiusy: 7, borderColor: false, fill: 'black', id: 'rightEye' ) path( borderColor: false, fill: 'darkOrange', id: 'beak' ){ moveTo( x:0, y:0 ) hline( x: 40 ) lineTo( x: 20, y: 20 ) transformations{ translate( x: 103, y: 80 ) } } image( file: 'c:\\tmp\\jerm-tiny-toux-3563.png', y: 180 )
You may download the full script from this link, please not that it will only work with graphicsbuilder-0.4.2-SNAPSHOT (currently on svn head at http://svn.codehaus.org/groovy-contrib/graphicsbuilder). I fixed some minor bugs along the way but noticed that even though graphicsPad is a good tool to start your own drawings, it lacks some features that would make life easier, like an optional drawing grid, rulers and a cheatsheet/help guide on available operations. I also noticed that skew will not always work as you expect, specially when combined with other transformations at the same time (I'm thinking a freeze option may come in handy) and sometimes when you resize the panel your drawing can go ballistic (something related to AffineTransform applied to the panel). When creating the flippers I kind of wished for flip (rotate+freeze) and reflect (scale+freeze) operations, they would have made the job easier.

As I mentioned on the previous post images are back, you can see an example of a local image being drawn (btw the original image is located at http://tux.crystalxp.net/en.id.3563-jerm-tiny-toux.html).

Seems that will all the minor fixes and new features graphicsbuilder-0.4.2 should be released soon, feedback is always welcome!

Keep on Groovying!
