| Adding bitmapped images |
You can import a bitmapped image into a drawing either
directly or by linking to an external image file. When you externally link
to an image file, any edits to the original file can be updated in the
imported file.
You can also add a bitmapped image by scanning it or by loading it from a
digital camera. |
| Applying special
effects to bitmapped images |
You can apply a wide range of special effects to bitmapped
images, such as three-dimensional and artistic effects.
Adding plug-in filters to CorelDRAW provides additional features and effects
that you can use to edit images. You can enable or disable plug-in filters
and you can remove them when you no longer need them. |
| Applying color
and tone effects |
CorelDRAW lets you apply color and tone to a bitmapped
image. For example, you can replace colors, shift them between RGB and CMYK
color modes. and adjust the brightness, lightness, and darkness of colors.
By applying color and tone effects, you can restore detail lost in shadows
or highlights, remove color casts, correct underexposure or overexposure,
and generally improve the quality of the bitmapped images. |
| Optimizing
bitmapped images for the World Wide Web |
| You can save objects and optimize them for the World Wide
Web. |
| Changing the
color mode of bitmapped images |
The colors of the images that you work with in CorelDRAW
are based on color modes. Color modes define the color characteristics of
images and are described by their component colors. The RGB
color mode is composed of red, green, and blue values and the CMYK color
mode is composed of cyan, magenta, yellow, and black values.
Although you may not be able to see the difference between an image in the
CMYK color mode and an image in the RGB color mode on screen, the images are
quite different. Colors from the RGB color space can cover a greater range
of the visual spectrum (that is, they have a larger color gamut) than those
in the CMYK color space. For the same image dimensions, a CMYK image has a
larger file size than an RGB image.
Each time you convert an image, you may lose color information. For this
reason, you should save an edited image before you change it to a different
color mode.
For more information about color modes, see "Working with color". |
| Changing
bitmapped images to the Black-and-White color mode |
| You can change any image to the 1-bit Black-and-White color
mode. In addition to conversion settings such as threshold, screen type, and
intensity, there are seven conversion options that affect how the converted
images will look. |
| Changing
bitmapped images to the Duotone color mode |
To convert an image to the Duotone color mode, you can
change a bitmapped image to the grayscale color mode and enhance it using
one to four additional inks, giving the image greater tonal depth.
The following four variations of the color mode correspond to the number of
additional inks:
Monotonea grayscale image colored with a single ink
Duotonea grayscale image colored with two inks. In most cases, one ink is
black and the other ink is colored.
Tritonea grayscale image colored with three inks. In most cases, one ink is
black and the other inks are colored.
Quadtonea grayscale image colored with four inks. In most cases, one ink is
black and the other inks are colored.
Adjusting tone curves
When you change an image to the Duotone color mode, a tone curve grid that
represents the dynamic ink curves that are used throughout the conversion is
displayed. The horizontal plane (x-axis) displays the 256 possible shades of
gray in a grayscale image (0 is black; 255 is white). The vertical plane
(y-axis) indicates the intensity of an ink (from 0 to 100 percent) that is
applied to the corresponding grayscale values. For example, a grayscale
pixel with a color value of 25 is printed with a 25-percent tint of the ink
color. By adjusting the tone curves, you can control the color and intensity
of the ink that is added to an image.
Saving and loading inks
You can save an adjusted Duotone tone curve and ink settings and then load
them for use with other bitmapped images.
Specifying how overprint colors display
When you change an image to the Duotone color mode, you can specify which
colors will overprint when you print an image. Overprint colors are the
colors that have too much ink when two or more colors overlap. When you
display the image, each color is applied on the screen in sequence, creating
a layered effect.
You can view all instances in which the colors you choose for the Duotone
conversion overlap. Associated with each instance is the color that is
produced by the overlap. You can also choose new overprint colors to see how
they overlap. |
