The ratio of the width of an image to its height (expressed mathematically as x:y). For example, the aspect ratio of an image that is 640 x 480 pixels is 4:3.
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 to 64 bits per pixel (bpp), and determines the color depth of an image.
A brightness value that is considered black in a bitmap image. In Corel PHOTO-PAINT, you can set the black 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 black point at 5, all pixels with a value greater than 5 are converted to black.
black-and-white color mode
A 1-bit color mode that stores images as two solid colors — black and white — with no gradations. This color mode is useful for line art and simple graphics. To create a black-and-white photo effect, you can use the grayscale color mode.

An 8-bit grayscale image that stores color or mask information for another image. There are two types of channels: color and mask. Images have one color channel for each component of the color model on which they are based. In addition, some images use spot color channels. Each channel contains the color information for that component. Mask (alpha) channels store masks that you create for your images, and they can be saved with images in formats that support mask information, such as Corel PHOTO-PAINT (CPT) format.

client/server image map
A rarely used image map type that includes code for both client-side and server-side image maps. This type of image map automatically defaults to the user’s Web browser for image map processing. If the browser does not support image maps, the server uses the external map file to process information. Currently, most Web browsers support image maps, so client-side image maps are more common.

highlight, shadow, and midtone
Terms used to describe the brightness of pixels in a bitmap image. Brightness values range from 0 (dark) to 255 (light). 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. You can lighten or darken specific areas in images by adjusting the highlights, shadows, or midtones. A histogram is an excellent tool for viewing and evaluating the highlights, shadows, and midtones of images.
A rectangle with eight handles that encloses a selection in an image.
A histogram consists of a horizontal bar chart that plots the brightness values of the pixels in your bitmap image on a scale from 0 (dark) to 255 (light). The left part of the histogram represents the shadows of an image, the middle part represents the midtones, and the right part represents the highlights. The height of the spikes indicates the number of pixels at each brightness level. For example, a large number of pixels in the shadows (the left side of the histogram) indicates the presence of image detail in the dark areas of the image.

A printing term that refers to an area where underlying colors have been removed so that only the top color prints. For example, if you print a small circle on a large circle, the area under the small circle is not printed. This ensures that the color used for the small circle remains true instead of overlapping and mixing with the color used for the large circle.
A color model that contains a luminance (or lightness) component (L) and two chromatic components: “a” (green to red) and “b” (blue to yellow).
A transparent plane on which you can place objects in a drawing.

Mask tool operation modes that you must choose before you create or fine-tune a mask and its editable area. There are four mask modes: Normal, Additive, Subtractive, and XOR. The Normal mode (default) lets you select an area in an image. The Additive mode lets you expand the editable regions by selecting multiple areas in an image. The Subtractive mode lets you reduce the editable regions by removing areas from a selection. The XOR mode lets you select multiple areas in an image. If areas overlap, the overlapping regions are excluded from the editable area and added to the protected area.
An editing state that determines how the selected paint, object, or fill color combines with other colors in the image.
The visual effect of radiating curves created by superimposing two regular patterns. For example, a moiré pattern can result by overlapping two halftone screens of different angles, dot spacing, and dot size. Moiré patterns are the undesirable result of rescreening an image with a different halftone screen or with the same halftone screen on an angle different from the original.
The decorative artwork made by arranging small pieces of variously colored material to form pictures or patterns.
A color mode that displays images by using multiple color channels, each comprising 256 shades of gray.

The mask overlay makes it easy to distinguish between the editable and the masked (protected) regions in an image. When the overlay is applied, the masked areas are displayed in varying degrees of red (according to their transparency). The deeper the saturation of the red tint, the greater the degree of protection.
Overprinting is achieved by printing one color over another. Depending on the colors you choose, the overprinted colors mix to create a new color, or the top color covers the bottom color. Overprinting a dark color on a light color is often used to avoid registration problems that occur when color separations are not precisely aligned.
A video color filter that is commonly used to define the gamut of colors supported by television monitors in Europe and Asia.

To change the resolution and dimensions of a bitmap. Upsampling increases the size of the image; downsampling decreases the size of the image. Resampling with fixed resolution lets you maintain the resolution of the image by adding or subtracting pixels while varying the image size. Resampling with variable resolution keeps the number of pixels unchanged while changing the image size, resulting in lower or higher resolution than that of the original image.
The amount of detail that an image file contains, or that an input, output, or display device is capable of producing. Resolution is measured in dpi (dots per inch) or ppi (pixels per inch). Low resolutions can result in a grainy appearance; high resolutions can produce higher quality images but result in larger file sizes.

A level of tolerance for tonal variation in a bitmap.
A control available when you create a path from a mask. Threshold values range from 1 to 10 and determine the size of the angle required between two sections of a mask for a node to be created there. A low value produces more cusps, and therefore more nodes on the resulting path.
A miniature, low-resolution version of an image or illustration.
A control available when you create a path from a mask marquee. Tightness values range from 1 to 10 and determine how close the path’s shape will be to that of the marquee.

The distribution 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.
