How Do I Set the Resolution of Exported Bitmaps?

In a bitmap file, an image is stored as an array of pixels. The most commonly used formats  for bitmap files are tiff, png, and jpg.  When exporting an image to a bitmap file, a preview window will appear with text boxes to set the exported image width and height. These property values are entered in units of pixels. If the output is expected to be presented over a 5-inch width and you want to achieve a 300-pixel per inch resolution, then you should set the Width value to 1500. The export image file format is set by specifying the file extension. In some cases, you may not want to select the jpg format because of the potential for image-compression methods that reduce the quality of the image.
