JythonとJava2Dを使って、CD-ROMアイコンを作成

Jythonを使って、今回CD-ROMアイコンを作成してみました。

	g.fill(ell)


outf=None

try:
	outf=sys.argv[1]
	widthAndHeight=sys.argv[2]
except :
	print "Usage: jython paintcdrom.py outputfile.png size"

if outf==None or widthAndHeight==None :
	sys.exit()


w=lang.Integer(widthAndHeight).intValue()
h=w
mysize=awt.Dimension(w,h)

bimg=createImage(mysize)
g=bimg.getGraphics()
g.setRenderingHint(awt.RenderingHints.KEY_ANTIALIASING,awt.RenderingHints.VALUE_ANTIALIAS_ON)
paint(g,mysize)
g.dispose()

fos=io.FileOutputStream( outf )
imageio.ImageIO.write(bimg,"PNG",fos)
fos.close()

生成方法

出力するPNG画像ファイル名とそのサイズを指定します。

jython cdrom.py cdrom48.png 48

この例では、48x48サイズのCD-ROMアイコンを生成します。
