## Description

Constants and functions related to rendering checkerboards.

## Details

### GIMP_CHECK_SIZE

    #define GIMP_CHECK_SIZE     8

The default checkerboard size in pixels. This is configurable in the core but GIMP plug-ins can't access the user preference and should use this constant instead.

### GIMP_CHECK_SIZE_SM

    #define GIMP_CHECK_SIZE_SM  4

The default small checkerboard size in pixels.

### GIMP_CHECK_DARK

    #define GIMP_CHECK_DARK   0.4

The dark gray value for the default checkerboard pattern.

### GIMP_CHECK_LIGHT

    #define GIMP_CHECK_LIGHT  0.6

The dark light value for the default checkerboard pattern.

### gimp_checks_get_shades ()

    void                gimp_checks_get_shades              (GimpCheckType type,
                                                             guchar *light,
                                                             guchar *dark);

Retrieves the actual shades of gray to use when drawing a checkerboard for a certain GimpCheckType.

`type` : | the checkerboard type
`light` : | return location for the light shade
`dark` : | return location for the dark shade

Since GIMP 2.2
