Which units do I use to set image size?
By default, all images are converted with initially specified image size.
If you want to change image size or resolution, you should add "Resize" operation. Set image size in pixels or percent in standard settings of this operation.
If you do not want to use pixels, you can expand the operation and set needed units (inches or centimeters) and enter the needed size.
Note that when inches or centimeters are used to set image size, the specified image resolution is kept. In any case, you will see resulting image size in Pixel Dimension field.
