TOTD# 41: How I created transparent logo of GlassFish using Gimp ?

Posted by arungupta on August 18, 2008 at 9:18 AM PDT

I followed the href="http://geekswithblogs.net/timh/archive/2006/03/20/72797.aspx">original
instructions with Gimp 2.4.5.

  1. Open up the href="http://blogs.sun.com/arungupta/resource/images/glassfish_logo_large.png">original
    image in Gimp.
    The original image has an embedded color profile and needs to be
    converted to RGB. Opening the original image shows the following
    message:

    Click on "Convert".
  2. Select "Tools", "Selection Tools", "Fuzzy Select" as shown:



    src="http://blogs.sun.com/arungupta/resource/images/gimp-fuzzy-select.png">



    and click anywhere on the white background. There are numerous types of
    selection tools available but mostly the background needs to be made
    transparent.
  3. Select "Layer" menu item, "Transparency", "Add Alpha
    Channel" as shown:

  4. If "Add Alpha Channel" menu item is disabled then proceed to the next step.

  5. Select "Edit" menu item, "Clear" to make the selection
    transparent.
  6. Finally save the image with default settings. Make sure to
    give the extension as ".png", just specifying the file type as "PNG"
    does not automatically provide the right extension. And the transparent
    GlassFish image is href="http://blogs.sun.com/arungupta/resource/images/glassfish_logo_large_transparent.png">available
    here.

A complete set of GlassFish buttons (including these images) are available href="https://glassfish.dev.java.net/glassfish_buttons/">here
- feel free to use them!

How do you intend to use them ? :)
