Hi Dave,

I would recommend always setting the compression before saving. This makes code more explicit and easier to maintain. It also protects in the case that the default would change.

If you first load a graphic with TTiffGraphic, then save it, it will use the same compression. If you just create a TTiffGraphic and assign an image using Assign, then save the graphic, the default will be no compression; but I would still recommend to set the compression before saving.

Best regards,
