Suppose you have any image (PNG or JPG). This image has a white background and I need to make this background transparent.
I have tried with these examples:
convert original.png -background none transparent.png
convert original.png -background white -flatten -alpha off transparent.png
but with no desirable results.
How can I make it?
IMPORTANT: Using convert
command-line.
I am using ImageMagick 6.6.9-7 on Ubuntu 12.04.
What worked for me was the following:
convert test.png -transparent white transparent.png
That changed all the white in the test.png to transparent.
