linedraw fork with changes to get compatibility with python 3.
Differences from the original repository:
- Doesn't work with .tif files;
- Added compatibility with .png images with transparent background;
- Only the silhouettes of the figures are sketched;
In particular, this is no longer designed specifically for plotters but actually serves to achieve a nice effect in redesigning icon silhouettes.
Convert images to vectorized line drawings.
Convert an image to line drawing and export .SVG format:
$ python linedraw.py -i input.jpg -o output.svg -t 235 -s 4Command specs:
usage: linedraw.py [-h] [-i [INPUT_PATH]] [-o [OUTPUT_PATH]] [-b] [-t [INT_VALUE]] [-s [INT_VALUE]] [-nc] [-nh]
[--no_cv] [--hatch_size [HATCH_SIZE]]
[--contour_simplify [CONTOUR_SIMPLIFY]]
Convert image to vectorized line drawing for plotters.
optional arguments:
-h, --help show this help message and exit
-i [INPUT_PATH], --input [INPUT_PATH]
Input path
-o [OUTPUT_PATH], --output [OUTPUT_PATH]
Output path.
-b, --show_bitmap Display bitmap preview.
-t [INT_VALUE], --threshold [INT_VALUE]
Defines the brightness to which the lightest shapes are ignored.
(Use value between 200 and 250 to get good result!)
-s [INT_VALUE], --sigma [INT_VALUE]
Defines how tolerant the detection of the edges is.
(Use value between 1 and 10 to get good result!)
-nc, --no_contour Don't draw contours.
-nh, --no_hatch Disable hatching.
--no_cv Don't use openCV.
--hatch_size [HATCH_SIZE]
Patch size of hatches. eg. 8, 16, 32
--contour_simplify [CONTOUR_SIMPLIFY]
Level of contour simplification. eg. 1, 2, 3
