The scanner program.
Using the scanner program, pixel images are vectorise, which have been digitalised or loaded in PCX, TIFF or BMP format using a normal commercial scanner. Be aware that the tasks with the scanner, are subject to certain limits. Templates should be clean and black/white (b/w), i.e. all circular contours are to be identifiable. Copied templates often degrade the quality (copying equipment can blur the circular contours). Good results can be achieved with templates with ca. 3 to 5 times enlargement. Here, as a rule, reworking is not necessary.
A vectorised image can be matched, edited, supplemented by drawings, hatched or cleared in the CAD using many ancillary tools. The thus created graphic data can be further processed in other modules or saved in many formats.
Load Pixel file.
Input a monochromePCX, TIFF or BMP file. Grey shades or colour images are not suitable here and only generate an error message.
To set or delete individual pixels. For this the cursor is moved on to the point to be processed. The image point is set using and deleted using. The successful setting/deleting process is indicated acoustically. The input is abandoned (ending of Pixel editing).
using or outside the image or
Set in the rectangle / delete in the rectangle.
The area of the image to be framed by a rectangle is set/deleted. For this the input of two end points of the rectangle are expected. The input can be abandoned using .
The borders of the dark fields in the pixel image are searched for and saved in the ActLayer as closed vectorised contours.
Scan image Resolution [dpi]:
Grid resolution of the scanned image in dpi.
Type of path (Vectorisation process):
Calculation of smooth runs (arcs) create high quality with graphics with large fields and curves – is less suitable for very small characters (lettering).
