Slide 4

Desktop Publishing "Desktop Publishing" applications are utilized to consolidate content, cut craftsmanship, digitized pictures, and so on to deliver pamphlets, flyers, bulletins, and so forth. Slide 2 of 13 END

Slide 5

Pixel A picture on the screen is comprised of numerous little specks called "Pixels" (Picture Elements). The pixel measurements of the basic "standard size" picture from an advanced camera are 640 pixels wide x 480 pixels tall. Slide 3 of 13 END

Slide 6

Resolution "Determination" alludes to how little and near one another the pixels or specks are. The higher the determination, the more specks there are per inch, and the "clearer" the photo. A typical screen determination is 72 pixels for each inch. 300 specks for each inch and more prominent resolutions are regularly utilized on scanners and printers for higher quality pictures. Slide 4 of 13 END

Slide 7

Line Art (monochrome pictures) "Line Art" (monochrome) pictures comprise of pixels that are either on or off, so they just require one piece of storage room per picture pixel. Slide 5 of 13 END

Slide 8

"Grayscale" pictures comprise of pixels which can be different shades of dark. 8-bit Grayscale pictures can have 256 unique shades of dim and require one byte of storage room per picture pixel. Slide 6 of 13 END

Slide 9

"Halftone" gives the impact of shading by utilizing different examples of dab groupings, as is ordinarily found in daily paper pictures. Slide 7 of 13 END

Slide 10

RGB Color "RGB" remains for "Red-Green-Blue", the three essential shades of light. By joining different powers of each of these hues, any shading can be made. Slide 8 of 13 END

Slide 11

24-bit per pixel RGB shading utilizes one byte (8-bits) to depict the force of every essential shading, giving more than 16 million conceivable hues requiring three bytes of storage room per pixel. Slide 9 of 13 END

Slide 12

Image Compression If not "compacted", a 640 by 480, 24-bit RGB shading picture will require: 640 x 480 x 3 = 921,600 bytes of memory . Pictures are generally "compacted" with the goal that they will require less storage room thus they will download faster. Pressure for the most part results in a lessening in picture quality. Slide 10 of 13 END

Slide 13

Some Common Image Formats JPEG - Compressed picture group for photographic sort pictures with numerous hues (basic on web). GIF - Used for Clip Art and Icons or pictures with constrained hues (regular on web). PNG - (Portable Network Graphic) Can be utilized for pictures on the web requiring straightforwardness. TIFF - A fantastic photographic picture group. BMP - A photographic arrangement basic on the PC. PICT - A photographic configuration normal on the Mac. Slide 11 of 13 END

Slide 14

"Raster" versus "Vector" Graphics "Raster" pictures are "Pixel-Based", with the shade of every pixel separately characterized. Utilizing "Paint tools" you can choose, control, and alter singular pixels in a Raster Image. Raster illustrations can\'t be scaled to a higher determination without lost quality. Raster illustrations are more suitable for freestyle or imaginative pictures, for example, photos. Slide 12 of 13 END

Slide 15

Vector Graphics "Vector" design are "Object-Oriented", using geometric protests, for example, bends and polygons to speak to a picture. Utilizing "Draw tools" you can choose, control, and alter geometric articles in a Vector Graphic. Vector illustrations can be effortlessly scaled to a higher determination without loss of value. Vector representation are more fitting for visual depiction and specialized delineation where exactness and versatility is critical, for example, Computer-Aided Drafting (CAD). Slide 13 of 13 END
