使用 im4java 画一个圆圈

Question

I need to draw a circle and save it as an image in a directory. I want to draw the image using im4java. I have tried to create, but there is no IMoperation available in im4java. Any help???

Answer 1

im4java is a wrapper to execute ImageMagick commands from your java code.

As you want to call a custom command, not implemented in im4java as a standard method, then either extend im4java functionality to call this command (it is opensource) or use Apache Commons Exec to call this custom command.

The ImageMagick command to draw a circle is explained here:
