![]() ![]() ![]() Line drawings are normally used for many species descriptions. Such figures are of great value for species identifications. In biosystematics, descriptions of new plant and animal taxa are always combined with figures and plates in order to illustrate the anatomical parts and body details. Images help reading a text and explain immediately what that text would represent. The method has been developed drawing figures of terrestrial isopods and some examples are here given.Īiming to express a concept or convey a message, the use of a picture is certainly a clearer and understandable way compared to a text-only description. This method is noteworthy: it is very accurate, producing detailed lines at the highest resolution the raster lines appear as realistic ink-made drawings it is faster than the traditional way of making illustrations everyone can use this simple technique this method is completely free as it does not use expensive and licensed software and it can be used with different operating systems. ![]() The present work gives step-by-step instructions on how to make accurate line drawings with a new procedure that uses bitmap graphics with the GNU Image Manipulation Program (GIMP). Digital drawing techniques that use vector graphics, have already been described in literature to support scientists in drawing figures and plates for scientific illustrations these techniques use many different software and hardware devices. These may be produced by scanning conventional drawings, made with high precision technical ink-pens, which normally use capillary cartridge and various line widths. Nowadays only digital figures are accepted by the most important journals of taxonomy. ![]()
