The number of binary bits that define the shade or color of each pixel in a bitmap. For example, a pixel in a black-and-white image has a depth of 1 bit, because it can only be black or white. The number of color values that a given bit depth can produce is equal to 2 to the power of the bit depth. For example, a bit depth of 1 can produce two color values (2 1=2), and a bit depth of 2 can produce 4 color values (2 2 = 4).
Bit depth ranges between 1 and 64 bits per pixel (bpp) and determines the color depth of an image.

For example, scaling a rectangle that is 1 inch high and 2 inches wide by 150 percent results in a rectangle that is 1.5 inches high and 3 inches wide. The aspect ratio of 1:2 (height to width) is maintained.
segment
The line or curve between nodes in a curve object.
selection box
An invisible rectangle with eight visible handles that appears around any object you select using the Pick tool.
simple wireframe view
An outline view of a drawing that hides fills, extrusions, contours, and intermediate blend shapes. Bitmaps are displayed in monochrome.
size
To change an object’s horizontal and vertical dimensions proportionally by changing one of the dimensions. For example, a rectangle with a height of 1 inch and a width of 2 inches can be sized by changing the value of the height to 1.5 inches. A width of 3 inches automatically results from the new height value. The aspect ratio of 1:2 (height to width) is maintained.
skew
To slant an object vertically, horizontally, or both.
snap
To force an object that is being drawn or moved to align automatically to a point on the grid, a guideline, or another object.
source object
The object you use to perform a shaping action on another object, such as welding, trimming, or intersecting. The source object receives the fill and outline attributes of the target object.
See also target object.
splash screen
The screen that appears when Corel DESIGNER starts. It monitors the progress of the startup process and provides information about copyright and registration.
split blend
A single blend that is broken into two or more components to create a compound blend. The object where the blend is split becomes the end object for one component of the blend and start object for the other.
spot color
In commercial printing, a solid ink color that prints individually, one plate per spot color.
spread
In commercial printing, a type of trap that is created by extending the foreground object into the background object.
style
A set of attributes that controls the appearance of a specific type of object. There are three style types: graphic styles, text styles (artistic and paragraph), and color styles.
subpaths
Subpaths are the basic curves and shapes from which a single curve object is constructed.
subscript
Text characters that are positioned below the baseline of the other characters in a line of text.
subtractive color model
A color model, such as CMYK, that creates color by subtracting wavelengths of light reflected from an object. For example, a colored ink appears blue if it absorbs all colors except blue.
super nudge
To move an object in large increments by pressing Shift and an Arrow key. The super nudge value is multiplied by the nudge value to obtain the distance by which the object is moved.
See also nudge and micro nudge.
superscript
Text characters that are positioned above the baseline of the other characters in a line of text.
swap disk
Hard drive space used by applications to artificially increase the amount of memory available in your computer.
swatch
One of a series of solid-colored patches used as a sample when selecting color. A printed booklet of swatches is called a swatchbook. Swatch also refers to the colors contained in the color palette.
symbol
A reusable object or group of objects. A symbol is defined once and can be referenced many times in a drawing.
symbol instance
An occurrence of a symbol in a drawing. A symbol instance automatically inherits any changes made to the symbol. You can also apply unique properties to each instance, including size, position, and uniform transparency.
T
target object
The object you perform a shaping action on, such as welding, trimming, or intersecting with another object. The target object retains its fill and outline attributes while copying these attributes to the source objects used to perform the action.
See also source object.
template
A predefined set of information that sets the page size, orientation, ruler position, and grid and guideline information. A template may also include graphics and text that can be modified.
text frame
The rectangle that appears as a series of dashed lines around a block of paragraph text created using the Text tool.
text style
A set of attributes that controls the appearance of text. There are two text style types: artistic text styles and paragraph text styles.
texture fill
A fractally generated fill that, by default, fills an object or image area with one image instead of with a series of repeating images.
threshold
A level of tolerance for tonal variation in a bitmap.
thumbnail
A miniature, low-resolution version of an image or illustration.
tick
Invisible divisions to which your pointer gravitates.
tiling
The technique of repeating a small image across a large surface. Tiling is often used to create a patterned background for webpages.
tint
In photo editing, a tint often refers to a semitransparent color applied over an image. Also called a color cast.
In printing, a tint refers to a lighter shade of a color created with halftone screening — for example, a spot color.
See also halftone.
tonal range
The distribution of pixels in a bitmap image from dark (a value of zero, indicating no brightness) to light (a value of 255, indicating full brightness). Pixels in the first third of the range are considered shadows, pixels in the middle third of the range are considered midtones, and pixels in the last third of the range are considered highlights. Ideally, the pixels in an image should be distributed across the entire tonal range. A histogram is an excellent tool for viewing and evaluating the tonal range of images.
tone
The variations in a color or the range of grays between black and white.
transparency
The quality of an object that makes it easy to see through. Setting lower levels of transparency causes higher levels of opacity and less visibility of the underlying items or image.
See also opacity.
trapping
See color trapping.
tree view
A hierarchical view of folders, sub-folders, and files. In the Symbol manager docker, the tree shows the current document at the top, followed by collections and library files.
TrueType fonts
A font specification developed by Apple. TrueType fonts print the way they appear on the screen and can be resized to any height.
TWAIN
By using the TWAIN driver supplied by the manufacturer of the imaging hardware, Corel graphics applications can acquire images directly from a digital camera or scanner.
two-point perspective
An effect created by lengthening or shortening two sides of an object to create the impression that the object is receding from view in two directions.
U
underexposure
Insufficient light in an image.
See also exposure.
uniform fill
A type of fill used to apply one solid color to your image.
See also fill.
Unicode
A character encoding standard that defines character sets for all written languages in the world by using a 16-bit code set and more than 65, 000 characters. Unicode lets you handle text effectively regardless of the language of the text, your operating system, or the application you are using.
URL (Uniform Resource Locator)
A unique address that defines where a webpage is located on the Internet.
V
vanishing point
A marker that appears when you select an extrusion or an object to which perspective has been added. With an extrusion, the vanishing point marker indicates the depth (parallel extrusion) or the point at which the extruded surfaces would meet if extended (perspective extrusion). In both cases, the vanishing point is indicated by an X.
vector graphic
An image generated from mathematical descriptions that determine the position, length, and direction in which lines are drawn. Vector graphics are created as collections of lines rather than as patterns of individual dots or pixels.
See also bitmap.
vector object
A specific object within a drawing that is created as a collection of lines rather than as patterns of individual dots or pixels. Vector objects are generated from mathematical descriptions that determine the position, length, and direction in which lines are drawn.
W
watermark
A small amount of random noise added to the luminance component of the image pixels which carries information about the image. This information survives normal editing, printing, and scanning.
weld
To combine two objects into a single curve object with a single outline. A source object is welded to a target object to create a new object that takes on the fill and outline attributes of the target object.
white point
The measurement of white on a color monitor that influences how highlights and contrast appear.
In image correction, the white point determines the brightness value that is considered white in a bitmap image. In Corel PHOTO-PAINT, you can set the white point to improve the contrast of an image. For example, in a histogram of an image, with a brightness scale of 0 (dark) to 255 (light), if you set the white point at 250, all pixels with a value greater than 250 are converted to white.
Windows Image Acquisition (WIA)
A standard interface and driver, created by Microsoft, for loading images from peripheral devices, such as scanners and digital cameras.
Z
zoom
To reduce or magnify the view of a drawing. You can zoom in to see details or zoom out for a broader view.
ZIP
A lossless file compression technique that results in smaller file size and faster processing time.
