Hello (I come ask help)[edit]

I seen your File:254489 9016 hamentash 02.jpg, the background is white, If you can do the same for "my" File:Slingshot (weapon).JPG that should be great.

Anyway, can you tell me step by step how do this. I think this work (extract the exact thing of a picture) is really need for an encyclopedia. See you~ Yug talk 17:30, 8 Jun 2005 (UTC)

Hello Yug, the picture in question was not edited by me. But I can tell you a few ways to get rid of the background:
  1. When taking the picture, try to make sure that the background is uniform (minimal variation/patterns/texture) and preferably of a colour that is not found within the object itself. White is usually not a good choice, since there is very often some part of white within the object. Lightish blue is often a good colour to use as a background.
  2. Edit the picture in a paint programme (e.g., “Paint”, if you are running MS Windows): Use the “pipette” tool to select colours from the background, and then the “fill” tool to paste the colour into a field of a different colour. This process is simple, but tedious.
  3. When the background has all been changed to a uniform colour (e.g., bright blue), save the file and open it in a programme capable of image conversions — e.g., Irfanview. Now check what ID number the background colour you has. Save the image as a PNG or GIF file, selecting the option “transparent background” and specifying the colour ID number (e.g., “1” or “87”).
  4. An alternative (and better) way to do it if you have some more advanced software is to have the programme crop out the background and replace it with white. I don’t have such fancy software, so I cannot tell you whether this process can be entirely automatic or if you have to manually trace the edges.
Hope this is of help! :-) Olve 18:41, 8 Jun 2005 (UTC)
