svmconv v0.0.5

StarView Metafile converter

Installation

npm install svmconv

Important information

SVM file contains plots rendered into BITMAP file w/o alpha channel. This causes that the resulting file placed onto canvas with black background. To fix this - all points that have color rgb(0, 0, 0) are changed to rgb(255, 255, 255).

Please note this when converting svm.

Usage

var Parser = require('svmconv')
  , fs     = require('fs');

fs.open('Source.svm', 'r', function(err, fd) {
    fs.fstat(fd, function(err, stats) {
        var bufferSize = stats.size,
            chunkSize  = 512,
            buffer     = new Buffer(bufferSize),
            bytesRead  = 0;

        while (bytesRead < bufferSize) {
            if ((bytesRead + chunkSize) > bufferSize) {
                chunkSize = (bufferSize - bytesRead);
            }
            fs.read(fd, buffer, bytesRead, chunkSize, bytesRead);
            bytesRead += chunkSize;
        }

        var parser = new Parser();
        parser.parse(buffer, 'Source.svm', true);
        fs.close(fd);
    });
});

or

...
    // set 'render to file' flag as false
    parser.parse(buffer, 'Source.svm', false);
