Annotation
The advantages and disadvantages of a number of specialized computer programs for obtaining dimensional characteristics of biological objects by analysis of their digital images are considered in comparative terms. The authorial methodology of using a vector graphics editor Inkscape and a new online service SVGm (Scalable Vector Graphics measurer, https://svgm.cf) is proposed to measure the linear parameters of the objects in the images and to prepare the quantitative characteristics of objects and their different qualitative characteristics for the subsequent statistical analysis. An algorithm for working with Inkscape editor and SVGm online service is described in detail. Object images imported into Inkscape editor are measured using vector elements (lines, rectangles, circles, ellipses, polygons) and saved in the standard SVG format. Properties of vector figures of SVG files are converted by the online service SVGm in the measurement results shown in the table. The potential of the method is shown by the example of morphological measurements of various botanical objects.
