Hi John,

You need to use the XDotsPerInch and YDotsPerInch properties of TTiffGraphic. They are usally the same value. Note that change these fields does not resize the image. Lowering the resolution without resizing the image, will print a larger image when printing an image with "original size".

For example,

ImageScrollBox.Graphic := XDotsPerInch := 150;
ImageScrollBox.Graphic := YDotsPerInch := 150;


Best regards,
