Image Size

This parameter sets the actual size of the image, in pixels. The image is not necessarily displayed at this size; see fit in window. Larger sizes improve the image, at the expense of increased rendering time. To change image size, do one of the following:

The Image Size submenu includes standard sizes, a Custom option, and your most recently used non-standard sizes. Choosing Custom displays the Image Size dialog, allowing a non-standard size to be entered.

You can also use the following shortcuts to select a standard size:

Very large image sizes can potentially exceed available memory, degrading performance. To avoid this, use the poster option instead. The current image allocates four bytes per pixel for escape times, and three bytes per pixel for color values, so Image Bytes = Width × Height × 7 (approximately).
