Academic literature on the topic 'TrueType-Font'

Kurva bezier (baca : bes-ee-ay) merupakan sebuah kurfa parametrik yang sering diterapkan pada komputer grafis dan dalam bidang-bidang berhubungan lainnya. Kurva bezier sangat dikenal karena kemampuannya untuk menghasilkan kurva yang halus. Penelitian ini bertujuan untuk mengetahui peran kurva bezier dalam pembentukan huruf-huruf Font dan mencari perbedaan peran kurva bezier dalam pembentukan Font TrueType dan Font PostScript. Sedangkan manfaat dari penelitian ini adalah mengenalkan pada masyarakat cara kerja dan peran kurva bezier dalam pembentukan huruf-huruf Font. Font TrueType dan font PostScript merupakan font vektor yang sama-sama menggunakan kurva bezier untuk menggambarkan kontur-kontur glyph. Font TrueType menggunakan kurva bezier kuadratik yaitu kurva bezier berordo 2, Font PostScript menggunakan kurva bezier kubik yaitu kurva bezier berordo 3.

The work describes the theoretical foundations of modern methods of creating new fonts, that is, using information technology, specifically vector programs. It also marginally shows the history of the font, Roman writing, the basic division of its compositions and describes its individual elements. The next part of the project focuses on creating digital fonts and continues with bringing it to live using algorithms and methods that can easily be processed in Matlab programming language. The method of implementation of the bringing the typeface to live is described and presentation of the generated results are then shown in few examples. Attention is also paid to the coordinates system, which is very important to solve geometric transformations, and two-dimensional vector graphics, which are widely used in the design and to render the fonts. Bézier curves and cubic Bézier curves are described in further detail along with vector graphics rasterization. One part of this text describes very important de Casteljau algorithm. The last chapter focuses on implementation in Matlab programming language, the creation of curves, that means single font characters, and the ways of how the algorithm works with transformations. Some sample images showing transformations using different input arguments are displayed in this section as well. There is evaluation of the contribution of this application and the possibilities of further expansion at the end.

In thesis themes of typography and computer font of OpenType format is described in details. At the beginning attention is paid to historical development of typeface, where stress is laid mainly on development of Roman and white letter with their characteristics. Having presented basis of typography work is concentrated on topic of digital font with emphasis on possibilities of OpenType format. Further its characteristics and advantages were listed compared to another formats and it was evaluated as format appropriate also for creating font in education process. Letterspacing and kerning were mentioned between basic graphical modifications in creating fonts. In theoretical part of the thesis they were examined in available programs designed for creating font in OpenType format. Except free available means into summary were included also commercial types due to absence of more advanced instruments and functions with free available applications. In evaluation was found that the most convenient for education is Fontlab Fontographer commercial program, free Type lite and Fontforge indicated for Open-source platform. Practical part of the thesis is focused on two chosen programs for creating main font characteristics. The goal was to detect if it is possible to reach identical results when using both programs. Fontographer program enabled to use wide tool palette dedicated to vector graphic processing by means of Adobe Illustrator similar instrument. In the case of Type lite program there were rather less instruments, what is sufficient for elementary work and familiarization with creating of digital typeface. Freeware shortage is basic absence of kerning, spacing or hinting functions. Comparing program possibilities, it falls that freeware programs based on OS Windows with their functionality are sufficient only for entry level users. The best option within free available programs is Fontforge for OS Linux which supports mentioned typographic functions. Fontographer was recommended for teaching of basic characteristics of OpenType font format. Another goal of the thesis was creating of recommended work procedure for creating basic characteristics of OpenType font for students, that is enclosed at the end of the thesis.

In this thesis, we propose a method to capture the outline from the bitmap image of personal handwriting character automatically and make use of fewer Bezier curves with minimum distortion and then it can apply to the TrueType font. In the system binary handwriting images are used as input, the contour of handwriting character is found first by the boundary following algorithm. Then the corner detection method that based on the eigenvalues of the covariance matrix of boundary points over the support region and it divide the contour into several segments. Therefore, we could fit quadratic Bezier curve to each segment. However the Bezier curve is not always the best fitting and it needs to break the segment into two segments. So finally we apply the step of reparameterization on the segment, and the purpose of this step is finding the best parameter of quadratic Bezier curve to reduce the number of Bezier curves that describe the outline of personal handwriting character. In this thesis, user through the tablet of Waltop WCK-C121 with handwriting software of Royal e-pen e-Calligraphy v 1.6.4 firstly, and then we can obtain the handwriting images by it. Experimental results have shown that the proposed methods of capturing outlines can robust in noisy contour of handwriting character and the outlines are described using of less quadratic Bezier curve and it is similar to the handwriting character.
