While these are all based on the same basic vector data model, they can interpret and structure shapes very differently, using very different file formats. Graphic design and illustration, using a vector graphics editor or graphic art software such as Adobe Illustrator. See Comparison of vector graphics editors for capabilities.
The Adobe Illustrator Artwork format is the native Illustrator file format. It is a proprietary file format developed by Adobe Systems for representing single-page vector-based drawings in either the EPS or PDF formats. The .ai filename extension is used by Adobe Illustrator. The AI file format was originally a native format called PGF.
Adobe Illustrator has a facility to trace individual curves. [3] Automated programs can have mixed results. A program (PowerTRACE) was used to convert a PNG map to SVG. The program did a good job on the map boundaries (the most tedious task in the tracing) and the settings dropped out all the text (small objects). The text was manually re-inserted.
Blending with black produces no change, as values for all colors are 0. (The RGB value for black is (0,0,0).) Blending with white inverts the picture. One of the main utilities for this is during the editing process, when it can be used to verify alignment of pictures with similar content. Exclusion is a very similar blend mode with lower contrast.
Common color depths are 2, 4, 16, 256, 65,536 and 16.7 million colors. The JPEG and PNG image formats are capable of storing 16.7 million colors (equal to 256 luminance values per color channel). In addition, grayscale images of 8 bits or less can be created, usually via conversion and down-sampling from a full-color image.
Go to the "Fill and Stroke..." option ⇧ Shift+Ctrl+F in the Object menu to adjust the color of the text. Right below the Fill tab, make sure the square next to the x is clicked. The vast majority of text will be black. Change the text in the RGBA: box to 000000ff. The first six characters correspond to the color's hex triplet.
One difference between photography and other forms of graphics is that a photographer, in principle, just records a single moment in reality, with seemingly no interpretation. However, a photographer can choose the field of view and angle, and may also use other techniques, such as various lenses to choose the view or filters to change the colors.
Encapsulated PostScript (EPS) is a Document Structuring Convention (DSC) conforming PostScript document format usable as a graphics file format.The format was developed as early as 1987 by John Warnock and Chuck Geschke, the founders of Adobe, together with Aldus. [1]
