Convert .png to .gif in java 1.5

Question

I have a QR code generated in .png format. I want this file to be converted into .gif format for using it in a device. I was trying to use ImageIO class but gif is not supported in java 1.5 but in java 1.6 . Our production servers has java 1.5 and is there any way to convert a .png file to .gif using Java 1.5?

Answer 1

I'd rather use some command-line conversion tool (eg ImageMagick). But if in your environment that's not possible or practical, and if you want to do it in Java, you can try this backport .

Bear in mind that the conversion is not trivial if the PNG is true colour or has transparency, GIF is more limited.

Answer 2

Direct conversion from png to gif is not possible. so First try to convert png to jpg format and try to convert jpg to gif format.
