PICT - Export | ||
Macintosh Picture (PICT) is a format used extensively with Mac OS versions prior to OS X, sometimes referred to as the "Classic" environment. It is a bitmap format that can handle up to 24 bit color. The Dots Per Inch (DPI) parameter is used to define the resolution or quality of the exported representation. Normal display screen viewing requires about 72 DPI for acceptable visual quality. Printed applications usually require 300 DPI for good quality representation. High quality printed results may need 600 DPI or greater. The size of a PICT file depends directly on the imaged area and complexity of the image. It grows rapidly (square law) as the DPI is increased. 2400 DPI may be prohibitively large even for small drawings. Keep in mind that we cannot regenerate an EazyDraw vector representation from a PICT export file. If your final work needs to be PICT (or any other bitmap format) be sure to Save and archive the EazyDraw original in case modifications to the work are needed in the future. You can always generate a revised PICT export from the original-but the reverse is not possible.
EazyDraw uses vectors to define all graphics. A vector representation does not need to record each dot along a curve. For example only 4 dots are needed for a full Beizer curve segment. The size of a vector representation is driven by the amount of content, not size and detail. A small icon containing numerous curves, colors and shading can result in a very large vector based representation. The TIFF representation of this example would require only a small file at 72 DPI. These are the trade-offs that are important, especially if the work product is intended for communication over networks or the internet. If your recipients require Mac OS 8 or 9, PICT format may be preferred. EazyDraw is a native Mac OS X application and cannot be used in the Classic Environment. |
