- 1. STANDARDS OF GRAPHIC DOCUMENTS .
- 2. Graphic Documents Bitmap Vector
- 3. Bitmap Documents Pixel Resolution e.g. 800x600 pixels, 3 Megapixels 4x3, 16x9 Raster
- 8. BMP (BitMaP) DIB (Device Independent Bitmap) No compression No transparency (24-bit) 32-bit DIB alpha channel- XP logo
- 9. JPEG (Joint Photographic Experts Group) ISO 10918-1 Compression enabled format (levels) 10:1 compresson with little loss No transparency (24-bit) Best for smooth variation of tone and colors Not good for sharp contrasts
- 10. GIF (Tagged Image File Format) Compression enabled format 3:1 compresson lossless + LZW Best for sharp-edged line art: logos, simple images Supports animations Can have only 256 colors in one image Allows transparency
- 11. PNG (Portable Network Graphics) RFC 2083/ ISO/EC 15948:2004 Compression enabled format- lossless Deflate True color and alpha transparency Best for sharp-edged line art: logos, simple images Faster interlacing than GIF Does not support animations
- 12. TIFF ( Tagged Image File Format ) Allows handling images and data in a single file (size, image-data arrangement, applied compression), even jpeg, layers and pages Compression enabled format- lossless LZW Bought by Adobe in 2009 Limited to 4 GB Custom tagging
- 13. RAW Direct sensor readout Myriad of RAW formats DNG (Digital Negative) standards proposal by Adobe Metadata, Compression (lossless and lossy), sometimes encription Open source dcraw
- 14. Vector Documents Use mathematical equations to present data Points, lines, curves, polygons Easier to manipulate with Don’t „loose” quality in any resolution Grouping objects Generally smaller size than bitmap
- 15. SVG (Scalable Vector Graphics) W3C open standards Defined using XML tagging Compatible with CSS specification Compression gzip or other http://upload.wikimedia.org/wikipedia/commons/6/6b/Bitmap_VS_SVG.svg
- 16. CDR (Corel Draw) Closed standard Ever changing
- 17. Have fun!
