Gimp.Palette.prototype.get_colormap
function get_colormap(format: Babl.Object): [return_value: ByteArray, num_colors: Number(gint), num_bytes: Number(gsize)] {
// Gjs wrapper for gimp_palette_get_colormap()
}
This procedure returns a palette's colormap as an array of bytes with all colors converted to a given Babl format.
The byte-size of the returned colormap depends on the number of colors and on the bytes-per-pixel size of format. E.g. that the following equality is ensured:
```C num_bytes == num_colors * babl_format_get_bytes_per_pixel (format) ```
Therefore num_colors and num_bytes are kinda redundant since both indicate the size of the return value in a different way. You may both set them to null but not at the same time.
Since 3.0
- format
The desired color format.
- return_value
The palette's colormap.
- num_colors
The number of colors in the palette.
- num_bytes
The byte-size of the returned value.
