Hi friends ,
I'm developing java image editor.
for that i want to give following funcanalities please tell me wheather it possiable or not.

1) Editor supoorts all Image file extenstions
like . BMP, GIF, PCX, PIC, JPE, PXR, PNG, RAW, TGA.
2) Set image resolution to 72 DPI (dot per inches ) . This funcanality for saving image with 72 DPI. ( This funcanality like "Save for Web" funcanality in PhotoShop ) . It reduces resolution and image size . Generally these images are used to send via email or uploading on web.
3) Add redo and undo funcanalities for enery image editing actions like crop , rotate ,brightness etc.
it is possible in Java or not ?
Give me some code or Java API name so i can implement them in my application.
Thanxs in adcance
