I Might Be Wrong

Preview of our new Maemo theme

Posted in Maemo, Python by Leif Ryge on September 21, 2008

Ian and I have been working on a new release of our LCARS packages, featuring a number of bug fixes as well as a new theme called “Okuda”:
"Okuda" theme running on N810

If all goes well, we should be ready to release this within the next 48 hours. All four of our themes now include icon templates, which we’re slicing with hildon-theme-slicer (the same way that the main theme template is processed). This is what the icon template for the Okuda theme looks like:
icon_template.png
Anyone else wishing to create a hildon-theme-tools (and ThemeMaker) compatible layout definition might find this Python script helpful:

#!/usr/bin/python2.5
"""Generate a hildon-theme-tools layout from variously sized images.
Edit script to specify desired margin, width, and origin (dx,dy).
usage: hildon-theme-layout-grid-generator.py `find icons|sort|grep png`
"""

__author__ = "Leif Ryge <leif @synthesize.us>"
__license__ = "no rights reserved / public domain"

from sys import argv
from PIL import Image

margin, width, dx,dy = 10, 600, 0,0 # margin, output width, starting coords
sizes = {}

for f in argv[1:]: sizes.setdefault(Image.open(f).size,[]).append(f)

print "[Main]\nTemplateWidth=%s\nTemplateHeight=%s\n\n[Elements]" % (width, \
    sum((h+margin)*(len(sizes[w,h])/(width/(w+margin))+1) for w,h in sizes) )

for w,h in sorted(sizes):
    column = width / (w+margin)
    row = 1 + len(sizes[w,h]) / column
    print "# %s images are %sx%s (%sx%s grid)" % (len(sizes[w,h]),w,h,column,row)
    for i, f in enumerate(sizes[w,h]):
        print "%s=%s,%s,%s,%s" % (f, dx+(i%column)*(w+margin),
                                     dy+(i/column)*(h+margin),w,h)
    dy = dy+row*(h+margin)

The actual template can then be created from existing images using Nokia’s hildon-theme-regenerator tool.
