(iv) Graphics with transparent areas
(v) Graphics displayed on computer screens
3) (a) Characteristics
(i) Native file format for Adobe Photoshop
(ii) Supports layers, transparency, text, and effects
(iii) Large file size
(b) Commonly used for:
(i) The industry standard for raster graphic creation and editing
4) (a) Characteristics
(i) Supports transparency
(ii) Uses lossless compression
(iii) Supports several different color depths; including 256 colors and 16 million colors
1. PNG 8 – 256 colors (Small graphics, line art, logos)
2. PNG 24 – Supports 16 million colors (Basic graphics, line art, logos)
(b) Commonly used for:
(i) Replacing GIF and TIFF images
(ii) Online viewing of images
5) The number of pixels in one inch. More pixels per inch means better image quality but larger file size.8) Some data is lost during compression and the greater the compression, the lower the quality of the image.11) refers to the mathematical algorithm used when an image is saved in order to reduce the file size.12) documents that are being sent for print should be 300 PPI to ensure image quality15) the background of an image is “see-through” so that the graphic can blend into the background without having a white box around it.16) assigns a percentage value for each of the process inks. If all of the percentages are set to 0, the result will be white. An image should be converted to CMYK color mode before exporting when images are being prepared for print.19) - the number of dots of ink or toner per inch on a printed image.
(a) The lower the DPI the less detailed the image.
(b) Images that will be printed need a higher resolution in order to print clearly without pixilation or blurriness.
23) the amount of detail stored for an image. The higher the resolution, the higher the level of detail in the image.25) width of the capital "M" , the current point size of the font.27) a unit of measurement for lines of type with one pica equal to 1/6 of an inch. Therefore, there are six picas in one inch. Picas are often used in print design, as they are more easily divisible than inches, such as with the Rule of Thirds. |
Across:
2) (a) Characteristics
(i) Does not support animation
(ii) Does not support transparency
(iii) Uses lossy compression
(iv) Supports 16 million colors
(v) High quality
(b) Commonly used for:
(i) Desktop publishing images
(ii) Photographs and natural artwork
(iii) Scanned images
(iv) Emailing photographs
(v) Digital camera photographs
6) assigns an intensity value to each pixel that ranges from 0 to 255 for each of the red, green, and blue components in an image. If all of the RGB values are 0 the result will be black. If all of the RGB colors are 255 the result will be white. RGB color is best used for on screen display.7) (a) Comprised of small dots called pixels, with each pixel assigned a color value.
(b) Can support high color depths.
(c) Edited in paint programs.9) refers to the number of colors per pixel that can be displayed in an image and affects image quality and file size.10) any proportion or share in relation to a whole.13) (a) Characteristics
(i) Does not support animation or transparency
(ii) Available in compressed (lossless) and uncompressed formats
(iii) Supports up 16 million colors
(b) Commonly used for:
(i) Storing raw bitmap data by some programs and devices such as scanners
(ii) High resolution printing
(iii) Desktop publishing images
(iv) Storage container for faxes and other digital images
14) the standard unit of measurement for US standard size papers that can work well for print. A “Letter” size piece of paper measures 8.5” x 11”, which is the most common size used in printers, for resumes, and other common desktop publishing documents.17) no data is lost during compression.18) a mathematical model that describes the way colors can be represented as numbers or percentages, typically with three or four values.20) file formats that can be used with a variety of software programs. Standard file formats are usually created by using the “Save As” command or through exporting. Standard file formats include, but are not limited to: .gif, .jpg, .png, and .tif.21) are digital photographs, also called bitmaps, are images composed of grids of pixels that have a fixed resolution (number of pixels per inch) and cannot be resized without losing image quality, edited in paint programs.22) the standard unit of measure for typefaces, with 1 point representing 1/72 of an inch, therefore text formatted in 72 point font should be approximately one inch with variation due to font designs. 12 point font is generally accepted as the standard font size for paragraph text in print.24) editable file formats that are proprietary to a specific program that generally lacks portability and is not meant to be used with other software. examples are: PSD26) anything on a page that is not actual text, from simple line drawings to fully active images found on the World Wide Web. The two major categories of graphic images are raster and vector.28) the most common unit of measurement used for computer screen display. A pixel generally represents one dot that is illuminated on a computer screen, many of which make up images. Pixels represent a precise measurement system for web-design, but can lack flexibility as screen size changes.29) monitors can display an image at a resolution of 72 ppi. Additional resolution beyond 72 ppi will increase file size without a noticeable increase in image quality.30) ease at which files are opened, modified, and viewed on computers using different operating systems, software and browsers. |
