Presentation Transcript

  1. Zapisi slik Slika je zapisana v datoteki. Zapis odvisen od programa. Formati slik brez kompresije - stiskanja: • BMP tudi PCX (bit map picture) Vsak piksel je posebej zapisan – velike datoteke • TIFF (Tagged Image File Format) Format za prenos slik med različnimi sistemi

  2. Zgoščevanje zapisa • Z zgoščevanjem skrajšamo daolžino zapisa podatkov – manjša datoteka • Lahko so: • Z izgubami • Brez izgub

  3. GIF zapis • Graphic interchange format omogoča le 8 bitov za barve. 256 barv na razpolago • Slike z malo barvami • Omogoča eno prozorno barvo • Omogoča več slik v eni datoteki – preprosta animacija

  4. JPEG format • Joint Photographic Expert Group • Izguba podatkov pri stiskanju • Ne izgubi barv PNG zapis • Portable Network Graphic • Kakovostni zapis slik • Animacija • Več prozornih barv

  5. Slikovni učinki • Svetlost • Kontrast • Ostrina • Spreminjanje barvne palete • Senčenje
