## 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
