This is called object-orientated programming (OOP) because objects are coded to interact in a visual environment.
The only exception is if I have hard lines or writing on the background – then I might use a PNG for the world background as well. Greenfoot is software that uses the programming language Java to make simple games.
Taken together, this means: Use JPEG files for scenario backgrounds – they are just about perfect for this, since we have fairly large images and don’t need transparency. However, it does not compress as well as JPEG, especially on images with many colours. Drag a bomb on top of a balloon to make an explosion that will wipe out many balloons at once. It has good quality for images, line drawings and text, and it can do transparent backgrounds. The other disadvantage is that JPEG does not do transparency, so if you want non-rectangular actors, this is a problem. While the PNG image looks fine, the JPEG image develops compression artefacts (“dirty” or “blurry” looking areas around the text). Look, for example, at the images on the right.
The IDE provides you with standard Java code and combines it with visual execution as well as a large help file which makes it a.

Greenfoot allows you to build Java simulations for graphical programs and games in an interactive way.
This does not make much of a difference in full colour images, but will become visible in images that have sharp lines on them (for instance, writing or line drawings). Write simulations in Java easily using a variety of intuitive tools with this handy and efficient application. On the downside: JPEG compromises on quality. So JPEG files are good for relatively large images if we want to save file size.
Small sizes are especially important if you want to export your scenario to the Greenfoot Gallery: The smaller the scenario files, the faster it is for you to upload your scenario and, more importantly, the faster the scenario starts for your users. JPEG is very good at compressing image files to a small size. Computer forensics (Networks intrusions & cyber crimes) ECS-Council. Computer forensics (Investigating data & image file ) ECS-Council.

Greenfoot is image processing software, that can be used to learn Java programming language, especially to making a 2D game. But there is also one other detail: Some image formats can have transparent areas (thus showing non-rectangular images) while others cannot. The trade-off with image formats is usually between file size and quality. Greenfoot can read most of them, but not all are equally good to use. Many different image file formats exist: JPEG, GIF, PNG, BMP, TIFF, PICT, and many more.
