Description

IMPORT_IMG Import and convert image to geometry.

[ GEOM ] = IMPORT_IMG( FILENAME, RES, SCALE, LEVEL, BORDER ) Import bitmap image with FILENAME image (JPG, PNG, BMP, TIFF), extract contours, and convert to a geometry of closed polygons.

RES specifies the resolution in pixels of the polygon segments (default 10 segments). SCALE is used for scaling from pixels to geometry dimensions (default 1 = one geometry length unit per pixel). LEVEL is used to prescribe an object detection threshold using the image color/intensity level (0 < LEVEL < 1, default 0.5). With the BORDER flag set an inverted border is added around the image (unset by default).
