calculateRowstride

fun calculateRowstride(colorspace: Colorspace, hasAlpha: Boolean, bitsPerSample: <Error class: unknown class>, width: <Error class: unknown class>, height: <Error class: unknown class>): <Error class: unknown class>

Calculates the rowstride that an image created with those values would have.

This function is useful for front-ends and backends that want to check image values without needing to create a GdkPixbuf.

Return

the rowstride for the given values, or -1 in case of error.
