Ontology of Heterogeneous Image File Formats.pdf
- 1. ONTOLOGY OF HETEROGENEOUS IMAGE FILE FORMATS AND THEIR DISPARATE APPLICATIONS (RESEARCH PRESENTATION) H.M.L.P.HERATH
- 2. CONTENT • INTRODUCTION • IMAGE FILE FORMAT • CLASSIFICATION OF IMAGE FILE FORMAT • RASTER VS VECTOR • TIFF (.TIF, .TIFF) • BITMAP (.BMP) • JPEG (.JPG, .JPEG) • GIF (.GIF) • PDF (.PDF)
- 3. INTRODUCTION IMAGES ARE IMPORTANT FOR COMMUNICATION AND COME IN VARIOUS DIGITAL FORMATS (COMPRESSED, UNCOMPRESSED, VECTOR) SUITED FOR SPECIFIC NEEDS. THIS PRESENTATION EXPLORES COMMON FORMATS LIKE TIFF, PNG, JPG, EXPLAINING THEIR STRENGTHS AND GUIDING YOU TO CHOOSE THE RIGHT FORMAT FOR OPTIMAL IMAGE QUALITY, SIZE, AND USES.
- 4. IMAGE FILE FORMAT • IMAGE FILE FORMATS ARE SPECIFICATIONS FOR STORING DIGITAL IMAGES. • THEY ENCODE IMAGE INFORMATION INTO BITS OF DATA. • COMMON IMAGE FILE FORMATS INCLUDE JPEG, PNG, GIF, TIFF ETC. • THE FILE EXTENSION IDENTIFIES THE FORMAT AND HELPS PROGRAMS TO OPEN THE IMAGE CORRECTLY.
- 5. CLASSIFICATION OF IMAGE FILE FORMAT Image file format Raster TIFF BMP JPEG GIF PNG Vector SVG PDF
- 6. RASTER VS VECTOR Feature Raster Images Vector Images Composition Composed of pixels Composed of paths and mathematical formulas File Sizes Larger Smaller Color Blending Rich and easily blendable Difficult without rasterizing Scaling Quality loss with dimension/resolution change Scalable without quality loss Editing Explicit, detailed editing Less detail, focuses on shape and line adjustments. Software Examples GIMP, Photoshop CorelDraw, Inkscape, Illustrator Common File Types .gif, .jpg, .png, .tif, . .svg, .pdf
- 7. TIFF (.TIF, .TIFF) • STANDS FOR: TAGGED IMAGE FILE FORMAT. • LOSSLESS COMPRESSION: HIGH-QUALITY IMAGES WITH NO INFORMATION LOSS. • LARGE FILE SIZES: SUITABLE FOR HIGH-RESOLUTION IMAGES BUT CAN TAKE LONGER TO LOAD. • LIMITED BROWSER SUPPORT: NOT NATIVELY SUPPORTED BY MOST WEB BROWSERS. • WIDE APPLICATIONS: USED IN PHOTOGRAPHY, ARCHIVING, PUBLISHING, AND HIGH-QUALITY PRINTS.
- 8. BITMAP (.BMP) • DEVELOPED BY : MICROSOFT • RASTER-BASED: PIXEL-COMPOSED, DETAIL-RICH IMAGES. • LARGE FILE SIZES: HIGH-RESOLUTION IMAGES RESULT IN LARGER FILES. • RICH COLORS: SUPPORTS A WIDE COLOR PALETTE AND BLENDING. • LIMITED SCALABILITY: DIFFICULT TO SCALE OR EDIT WITHOUT QUALITY LOSS.
- 9. JPEG (.JPG, .JPEG) • STANDS FOR: JOINT PHOTOGRAPHIC EXPERTS GROUP (DEVELOPED IN 1992) • LOSSY COMPRESSION: SMALLER FILE SIZE WITH POTENTIAL QUALITY TRADE-OFF • POPULAR FORMAT: WIDELY USED BY DIGITAL CAMERAS & INTERNET • APPLICATIONS: PHOTOGRAPHY, SOCIAL MEDIA & MORE • STORAGE EFFICIENCY: ENABLES STORING MORE IMAGES
- 10. GIF (.GIF) • STANDS FOR : GRAPHICS INTERCHANGE FORMAT • DEVELOPED BY : COMPUSERVE, AN ONLINE SERVICE PROVIDER BACK IN 1987. • LIMITED COLOR PALETTE: SUPPORTS UP TO 256 COLORS. • LOSSLESS COMPRESSION: ENSURES CLEAR GRAPHICS WITHOUT QUALITY LOSS. • USE FOR : ANIMATIONS & WEB . • STATIC IMAGES & PORTABILITY: IDEAL FOR CLEAR, LIGHTWEIGHT WEB GRAPHICS.
- 11. PNG (.PNG) • STANDS FOR : PORTABLE NETWORK GRAPHICS • OPEN-SOURCE LOSSLESS FORMAT: OFFERING ENHANCED FEATURES & ALTERNATIVE TO GIF. • SUPERIOR COLOR HANDLING: SUPPORTS A BROAD COLOR SPECTRUM, IMPROVING PORTABILITY. • WEB-OPTIMIZED: EXCELLENTLY SUITED FOR DIGITAL PLATFORMS, LESS SO FOR PRINT. • SMALLER FILE SIZE: PROVIDES QUALITY IMAGES WITH REDUCED STORAGE REQUIREMENTS.
- 12. PDF (.PDF) • STANDS FOR : PORTABLE DOCUMENT FORMAT • CREATED BY : ADOBE (1993) • VERSATILE FORMAT : VECTOR & RASTER GRAPHICS • MORE THAN DOCUMENTS : ATTACHMENTS , ENCRYPTION, AND METADATA • USE FOR : PRINTING SHARING PRESENTATIONS, EBOOKS, FORMS, ETC
