i read so many forums views that pixels base graphics are some times becomes problem like making the application performance bad and slow, while on other hand pictures eg png etc are better but they take size alot if u will make them in photoshop or any other editor....instead of them is there any other way to create graphics ? and making rectangle and squares are they also come in the catagory of pixel base work?
You can use any .png optimizer to shrink .png size, but they would't help too much. Some device supports .jpg file format. Much smaller file size, but that's a lossy compress, takes more time to decode, and same size in memory.
