Studying Visual Aspects of the Letters in Nastaliq

At the present time, considering the rapid wide functions, which are expected to line and calligraphy, writing and focus on Nastaliq is an urgent need. Due to the limitations of Nastliq issues and the lack of a comprehensive resource for the study of its components, it is the most required research. The aim of writing this article is to achieve scientific results with an emphasis on the fundamentals of visual arts. According to this study, after studying the Nastaliqs geometrical forms and compare them with each other, we hope we will be able to achieve similarities between them. Structural features of the letters can be examined from different aspects, but this research focuses just on form features of the Nastaliq letters. For example, the strengths and weaknesses, the start and the end of each letter, the word position and the relationship between negative and positive space. So this research will be based on quantitative aspects. After gathering data, all measured by computer, we can say that, the first part is indicating the letter identity. Given that the end of the letters in Nastaliq move upward and negative space of the letters appear at the end of them, so this feature let the letters combine with each other. The size and position of the letters are related to the baseline. Also the relation between close and wide angles follows a logical structure which is shown statistically in the table.
