For long times, I am wondering how people are creating the Picture Messages for Mobile phones.
I could not imagine with my old Nikia 2300 mobile.
I upgraded to Sony Ericsion w770i recently.
I find that I can save the Picture Messages separately.
I copied the Picture Messages to my computer.
That File Format is wbmp.
see more on http://en.wikipedia.org/wiki/Wbmp
It is Wireless Application Protocol Bitmap.
But How to open and edit it?
Which graphic application supports wbmp format?
The search went for a long time.
After making the google tired, i leaved it.
When I was searching, I found a nice article by My friend Girish Venkatachalam.
Imagemagick is a powerful commandline utility, which do wonders.
it can manipulate a lot of works on images.
It is a set of tools, where “convert” is one of that.
convert can do magics on images.
it can resize, add text, colorize, modify the brightness/contrast, resize, zoom, crop etc.
It handles all the image formats.
so, I took a wmbp file and tried to convert it into normal bmp format.
convert test.wbmp test.bmp
viola! It worked. There is GIMP to do change the bmp image.
Then, I sat and played with GIMP to create various Picture Messages.
After the editing finished, now again, we have t convert the bmp into wbmp.
convert sample.bmp sample.wbmp
Put the newly created wbmp image into mobile phone.
And started forwarding the PICTURE Message to all my friends.
Using this method, I will all my friends on their birthday with a handmade birthday wish message with, their name on the messge.
The wbmp image should have the resolution of 72 x 28 pixels.
It should be monochrome. i.e Black and White.
No other colour is acceptable.
