# READ_PICT

The READ_PICT procedure reads the contents of a PICT (version 2) format image file and returns the image and color table vectors (if present) in the form of IDL variables. The PICT format is used by Apple Macintosh computers.

This routine is written in the IDL language. Its source code can be found in the file `read_pict.pro` in the `lib` subdirectory of the IDL distribution.

Note: To find information about a potential PICT file before trying to read its data, use the QUERY_PICT function.

## Examples

To open and read the PICT image file named `foo.pict` in the current directory, store the image in the variable `image1`, and store the color vectors in the variables R, G, and B, enter:

READ_PICT, 'foo.pict', image1, R, G, B

To load the new color table and display the image, enter:

TVLCT, R, G, B

TV, image1
