Brightness: Slider to control the brightness value of all colors used.

" "

The brightness value can range from 0 to 200. Values greater than 100 will " " lighten the print. Values less than 100 will darken the print.

" "
" "
" "

Additional hint for power users: This KDEPrint GUI element matches " " with the CUPS commandline job option parameter: " "

			"

" "
" ); QString whatsThisHueImagePage = i18n( " " "

Hue (Tint): Slider to control the hue value for color rotation.

" "

The hue value is a number from -360 to 360 and represents the color hue rotation. " " The following table summarizes the change you will see for the base colors: " "

" " " " " " " " " " " " " " " " " "
Original hue=-45 hue=45
Red Purple Yellow-orange
Green Yellow-green Blue-green
Yellow Orange Green-yellow
Blue Sky-blue Purple
Magenta Indigo Crimson
Cyan Blue-green Light-navy-blue

" "

" "
" ); QString whatsThisSaturationImagePage = i18n( " " "

Saturation: Slider to control the saturation value for all colors used.

" "

The saturation value adjusts the saturation of the colors in an image, similar to " " the color knob on your television. The color saturation value.can range from 0 to 200." " On inkjet printers, a higher saturation value uses more ink. On laserjet printers, a " " higher saturation uses more toner. " " A color saturation of 0 produces a black-and-white print, while a value of 200 will " " make the colors extremely intense.

" "

" "
" ); QString whatsThisGammaImagePage = i18n( " " "

Gamma: Slider to control the gamma value for color correction.

" "

The gamma value can range from 1 to 3000. " " A gamma values greater than 1000 lightens the print. A gamma value less than 1000 " " darken the print. The default gamma is 1000.

" "

Note:

the gamma value adjustment is not visible in the thumbnail " " preview.

Image Printing Options

" "

All options controlled on this page only apply to printing images. " " Most image file formats are supported. To name a few: JPEG, TIFF, PNG, GIF, " " PNM (PBM/PGM/PNM/PPM), Sun Raster, SGI RGB, Windows BMP." " Options to influence color output of image printouts are: " "

    " "
  • Brightness
  • " "
  • Hue
  • " "
  • Saturation
  • " "
  • Gamma
  • " "

Coloration Preview Thumbnail

  • Saturation

Image Size: Dropdown menu to control the image size on the printed paper. Dropdown " " works in conjunction with slider below. Dropdown options are:.

" "
    " "
  • Natural Image Size: Image prints in its natural image size. If it does not fit onto " " one sheet, the printout will be spread across multiple sheets. Note, that the slider is disabled " " when selecting 'natural image size' in the dropdown menu.
  • " "
  • Resolution (ppi): The resolution value slider covers a number range from 1 to 1200. " " It specifies the resolution of the image in Pixels Per Inch (PPI). An image that is 3000x2400 pixels " " will print 10x8 inches at 300 pixels per inch, for example, but 5x4 inches at 600 pixels per inch." " If the specified resolution makes the image larger than the page, multiple pages will be printed. " " Resolution defaults to 72 ppi. " "
  • " "
  • % of Page Size: The percent value slider covers numbers from 1 to 800. It specifies the size " " in relation to the page (not the image). A scaling of 100 percent will fill the page as completely " " as the image aspect ratio allows (doing auto-rotation of the image as needed). " " A scaling of more than 100 will print the image across multiple " " sheets. A scaling of 200 percent will print on up to 4 pages.
  • " " Scaling in % of page size defaults to 100 %. " "
  • % of Natural Image Size: The percent value slider moves from 1 to 800. It specifies " " the printout size in relation " " to the natural image size. A scaling of 100 percent will print the image at its natural size, while a " " scaling of 50 percent will print the image at half its natural size. If the specified scaling makes " " the image larger than the page, multiple pages will be printed. " " Scaling in % of natural image size defaults to 100 %. " "
