Gimp Tutorial – How to make an image background transparent
1 ) Open your image and select the area you want to make transparent, in this instance we are going to select the black background. Use shift-click to add more regions/colors.
Tip: Use zoom in to see finer details of exactly what you’re selecting.
2 ) I am going to use the Fuzzy Tool. See images below.
You can see a white line around the red rose. This tells you that the black background has been selected
3 ) In the Layer window (the one showing your image), select Layer – Transparency – Add Alpha Channel. If this is blanked out then it’s already done. This makes sure your image can store transparency data.
4 ) Select Edit – Clear. This makes the selection transparent. See image below.
5 ) Export the file. I will export the file as a png format. This is one of the most widely use formats for the internet. See images below.
Note: Make sure you don’t select Save background colour because it can cause some issues.
Note: When you save the image as a PNG file, be sure to select the ‘Save colour values from transparent pixels’ option in the Save as PNG dialog box.
This is the end result
And that’s it. As you can see it is very simple.
I have added 2 flash videos 1 is a slideshow tutorial using wink and the other is a youtube video.
