Vector graphics play an important role in the field of image localisation, nevertheless, the subject of vector graphics localisation has not been sufficiently researched to this date. The purpose of this Master's thesis is to determine if CAT tools or image editors (in particular SDL Trados Studio 2015 and Inkscape 0.91) are better suited for the localisation of SVG files vy translation students or novice translators with little or no image localisation experience. Three characteristics laid out by the EAGLES evaluation method (functionality, usability and efficiency) and their corresponding sub-characteristics (suitability, accuracy, understandability, learnability, operability, attractiveness and the time behaviour) were analysed and evaluated through feature inspection, scenario test and questionnaire. The results of the study suggest that the CAT tool SDL Trados Studio 2015 is better suited for the localisation of Scalable Vector Graphics by users with little or no experience in the field.
