The blocky, but fast and colorful Lo-Res graphics mode (often known as GR after the BASIC command) was 40 pixels wide, corresponding to the 40 columns on the normal Apple II text screen. This mode could display either 40 rows of pixels with four lines of text at the bottom of the screen, or 48 rows of pixels with no text.
160 × 100 in 16 colors, chosen from a 16-color palette, utilizing a specific configuration of the 80 × 25 text This used 4 bits per pixel, with a total memory use of (160 * 100 * 4) / 8 = 8 kilobytes. 320 × 200 in 4 colors, chosen from 3 fixed palettes, with high- and low-intensity variants, with color 1 chosen from a 16-color palette.
Dodging lightens an image, while burning darkens it. Dodging the image is the same as burning its negative (and vice versa). Dodge modes: The Screen blend mode inverts both layers, multiplies them, and then inverts that result. The Color Dodge blend mode divides the bottom layer by the inverted top layer. This lightens the bottom layer ...
Firefox: Includes a PDF viewer; Google Chrome: Includes a PDF viewer; Preview: macOS's default PDF viewer; in Mac OS X v10.5 and later, it also can rotate, reorder, annotate, insert, and delete pages. It can also merge files, create new files from existing files, and move pages between files
High Efficiency Image File Format (HEIF) is a digital container format for storing individual digital images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio and video. [1] HEIF can store images encoded with multiple coding formats, for example both SDR and HDR images.
JPXDecode, a lossy or lossless filter based on the JPEG 2000 standard, introduced in PDF 1.5. Normally all image content in a PDF is embedded in the file. But PDF allows image data to be stored in external files by the use of external streams or Alternate Images. Standardized subsets of PDF, including PDF/A and PDF/X, prohibit these features.
In both the Apple II and the CGA, each line is elongated to full 228 cycles of the color subcarrier. This is within the tolerances of most displays, so the image is displayed clearly, but the pattern generated by solid colors becomes straight vertical stripes instead.
In graphics software, layers are the different levels at which one can place an object or image file. In the program, layers can be stacked, merged, or defined when creating a digital image. Layers can be partially obscured allowing portions of images within a layer to be hidden or shown in a translucent manner within another image.
