## DESCRIPTION

*wxpyimgview* is a simple wxWidgets image viewer for 32-bpp BMP images, as can be created with the *PNG* and *cairo* drivers. The display is continually refreshed.

## NOTES

The display driver must be configure to map the file, with *GRASS\_RENDER\_FILE\_MAPPED=TRUE*. This ensures that the file will remain a constant size, rather than being truncated whenever it is updated.

## SEE ALSO

*PNG driver,* *cairo driver*
