Watermark X Position

Defines the x-position of the watermark in relation to the left-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 mark-x parameter will overwrite mark-align=left, mark-align=center, mark-align=right, and mark-pad (in the horizontal direction) if set. Use mark-x[N] to style a specific additional watermark layer — styles do not inherit across watermark layers.
