Group 4 compression is available in many proprietary image file formats as well as standardized formats such as TIFF, CALS, CIT (Intergraph Raster Type 24) and the PDF document format. G4 offers a small improvement over G3-2D by removing the end-of-line (EOL) codes. G3 and G4 compression both treat an image as a series of horizontal black ...
InDesign exports documents in Adobe's Portable Document Format (PDF) and supports multiple languages. It was the first DTP application to support Unicode character sets , advanced typography with OpenType fonts , advanced transparency features, layout styles, optical margin alignment, and cross-platform scripting with JavaScript .
ColorCode 3-D, [21] [22] a anaglyph stereoscopic color scheme, uses the RG color space to simulate a broad spectrum of color in one eye, while the blue portion of the spectrum transmits a black-and-white (black-and-blue) image to the other eye to give depth perception.
Color images can be converted to black and white on the computer using several methods, including desaturating the existing color RGB image so that no color remains visible (which still allows color channels to be manipulated to alter tones such as darkening a blue sky), or by converting the image to a greyscale version (which eliminates the ...
To convert a color from a colorspace based on a typical gamma-compressed (nonlinear) RGB color model to a grayscale representation of its luminance, the gamma compression function must first be removed via gamma expansion (linearization) to transform the image to a linear RGB colorspace, so that the appropriate weighted sum can be applied to ...
Draw lines with simulated brushes of different color, size, shape and pressure; Fill a region with a single color, gradient of colors, or a texture; Select a color using different color models, e.g., RGB, HSV, or by using a color dropper; Edit and convert between various color models. Add typed letters in various font styles
A photograph of a neighborhood watch sign is the foreground color while the rest of the image is the background color. [1] In the document-scanning industry, this is often referred to as "bi-tonal". A binary image is a digital image that consists of pixels that can have one of exactly two
Variants of TIFF can be used within document imaging and content/document management systems using CCITT Group IV 2D compression which supports black-and-white (bitonal, monochrome) images, among other compression technologies that support color. When storage capacity and network bandwidth was a greater issue than commonly seen in today's ...
