Details #

dpi(axis) takes exactly one argument and returns a number. axis is "x" or "y"; anything other than y (compared without regard to case) is treated as x. Use "x" for the horizontal DPI and "y" for the vertical.

It reads the image the running action works on, which an action supplies in the image variable.

Parameters #

Takes 1 argument. {{ dpi(text) }}

Examples #

dpi("x")

→ 72

Sample variable	Value
`image`	`{"dpiX": 72, "dpiY": 144}`

dpi("y")

→ 144

Sample variable	Value
`image`	`{"dpiX": 72, "dpiY": 144}`

Gotchas #

With no image to read it stops the step: dpi() needs an image: it reads the image the running action works on. The examples set a sample image variable so they run.
Calling it with no argument is an error: dpi() takes 1 argument, got 0.
