blurhash value v15.0.0

Compute a blurhash placeholder for the given images : a ~30 character string a client paints as a blur while the real image loads

In pins 3 + flow

flow
flow
files required
file
The images to hash
components x
number
Horizontal detail, 1-9 (default 4). More components means a longer hash, not a sharper preview.
components y
number
Vertical detail, 1-9 (default 3)

Out pins 5 + flow

flow
flow
hash
value
Blurhash of the first image : the common case, so it does not need an array index
hashes
array
One blurhash per image, in input order
success
condition
True if every image hashed. False if one or more failed
errors
array
Error messages
failed
file
Images which could not be hashed

Computes blurhash placeholder strings for every image wired into the files pin. hash holds the FIRST image's hash for the common single-image case; hashes holds one hash per image in input order. components_x (default 4) and components_y (default 3) set detail, range 1-9; more components means a longer hash, not a sharper preview. success is true only when EVERY image hashed; failed images land on failed_file with their messages on errors.

A typical wiring for blurhash: a function trigger starts the flow; get file from assets feeds the file pin; the flow out pin feeds debug.
