fun calculateRowstride(colorspace: Colorspace, hasAlpha: Boolean, bitsPerSample: Int, width: Int, height: Int): Int
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
