Text Y Position
txt-y
Defines the y-coordinate of the text in relation to the top-most edge of the base image.
The value can be a positive or negative integer. If the value is negative, the image will be partially outside the base image boundary. The txt-y parameter will overwrite txt-align=top, txt-align=middle, txt-align=bottom, and txt-pad (in the vertical direction) if set. Use txt-y[N] to override this for a specific text layer — bare txt-y applies to every layer by default.
