[ Version ( since = "2.36.8" ) ]
public static int calculate_rowstride (Colorspace colorspace, bool has_alpha, int bits_per_sample, int width, int height)

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`.

Parameters:

colorspace

Color space for image

has_alpha

Whether the image should have transparency information

bits_per_sample

Number of bits per color sample

width

Width of image in pixels, must be > 0

height
