Abstract:
1. A method of producing a digital representation of an engraved image on a computer monitor, comprising: allowing a user to independently create a first individual line over an underlying digital image, the first line comprised of a first visible line portion of a first color surrounded by a first affected area portion of a second color, the first affected area portion defining a first area around the first visible line portion that extends around both sides of the second visible line portion, a width of at least one of the first visible line portion and the first affected area portion of the first line being automatically affected by a luminance of the underlying digital image according to preselected parameters that vary the width of at least one of the first visible line portion and the first affected area portion; allowing a user to independently create a second individual line proximate to the first line, the second line comprised of a second visible line portion of the first color surrounded by a second affected area portion of the second color, the second affected area portion defining a second area around the second visible line portion that extends around both sides of the second visible line portion, a width of at least one of the second visible line portion and the second affected area portion of the second line being automatically affected by a luminance of the underlying digital image according to preselected parameters that vary the width of at least one of the second visible line portion and the second affected area portion; controlling the spacing between the first and second visible line portions by varying at least one of the width of the first and second visible line portions according to the luminance of the underlying digital image and the width of the first and second affected area portions according to the luminance of the underlying digital image; and preventing the first and second affected areas in a first engraving mode from overlapping by abutting the first and second affected areas of the first and second lines to control the spacing of the first and second visible line portions according to a user selected width of the first and second affected areas to form a digital engraving of the underlying digital image according to the luminance of the underlying digital image.
