autocad - Plotting circles and arc without segmentation (PLT format) -

-

i'm having problems plotting vector objects such arcs , circles autodesk without forcing them set of lines. plt (hpgl) file format supports both circles , arcs defined through various means, reason, output uses lines.

the drawing i've created simple, testing purposes arc , circle drawing

and output plotting (i've separated commands single lines it's more readable)

now command circle in plt simple - ci 3 parameters - center x, y , radius. instead substituted bunch of lines.

i've tried various hp printers, seems make no difference driver support same, settled hp 7585b. i've tried increasing quality resulted in more points.

is there way 1:1 (as shape) vector graphics autocad plt? or there simple file format plt support this?

use dxf instead of plt. got 1:1 mapping.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
