Functions

• check_for_overflow 🔒
  Convenience function to check if the combination of width, length and number of channels would result in a buffer that would overflow.
• num_bytes 🔒
  Calculate how many many bytes a buffer holding a decoded image with these properties would require. Returns None if the buffer size would overflow or if one of the sizes are negative.
• set_1bit_pixel_run 🔒
• set_2bit_pixel_run 🔒
• set_4bit_pixel_run 🔒
• set_8bit_pixel_run 🔒
• with_rows 🔒
  Call the provided function on each row of the provided buffer, returning Err if the provided function returns an error, extends the buffer if it’s not large enough.
