GrADS Commands: printim

## printim

The `printim` command will produce a PNG, GIF, or JPG formatted image file based on the current contents of the metabuffer, which is usually the stuff displayed on the screen, minus any widgets. The syntax is:

`printim filename options`

where:

`filename:` The name of the output file. If this file exists, it will be replaced.
`` If the filename ends with ".png" or ".PNG" then GrADS will automatically create the image in PNG format
`` If the filename ends with ".gif" or ".GIF" then GrADS will automatically create the image in GIF format
`` If the filename ends with ".jpg" or ".JPG" then GrADS will automatically create the image in JPEG format

`options: png` - produce PNG output (default)
`gif` - produce GIF output
`jpg` - produce JPEG output
`black` - use black background (default is current display setting)
`white` - use white background (default is current display setting)
`xNNN` - horizontal size in NNN pixels
`yNNN` - vertical size in NNN pixels
`-t NN` - color number NN is transparent
`-b bgImage` - Image file `bgImage` s included in the background of the output.
`-f fgImage` - Image file `fgImage` is included in the foreground of the output.

One or more `options` may be given in any order. `bgImage` and `fgImage` must be PNG format.

### Usage Notes

1. `printim` works with GrADS version 1.8 (or higher).
2. `printim` can be used while in batch mode.
3. The option for JPEG formatted output became 'official' with version 2.0.a5.

### Examples

The following command produces a 1000x800 PNG image into file out.png:

`printim out.png x1000 y800`

This command produces a 800x600 GIF image, with a white background, into file gifimage.out:

`printim gifimage.out gif x800 y600 white`

This command produces a GIF image with transparent color 0 and a background image mybkg.png. This means that in image.gif, the background image mybkg.png will be seen wherever the color 0 (background) appeared in the current display.

`printim image.gif -b mybkg.png -t 0`
