Designing and implementing GUI for PDF Editor
Pešková, Eva ; Mišutka, Jozef (advisor) ; Lasák, Petr (referee)
Thesis analyses existing PDF editors and focuses on creating new one that is user-friendly, simple and easy-to-use. The final product contains basic operations with text, images and annotations. It is also possible to view the changes via version control. Implementation was based upon existing project PDFEdit, created as a Software Project for Faculty of mathematical and physics at Charles university. It is using QT4 library for creating graphical user interface. The final product will be distributable to Windows-class operating systems via installation file and on system based on Unix via Makefile.

A Tool for Transformation of PDF to Text
Bujok, Jonáš ; Raab, Jan (advisor) ; Hauzar, David (referee)
Title: A Tool for Transformation of PDF to Text Author: Jonáš Bujok Department: Institute of Formal and Applied Linguistics (32-UFAL) Supervisor: Mgr. Jan Raab, Institute of Formal and Applied Linguistics (32-UFAL) Abstract: In this thesis we described an extraction procedure of text information from PDF (Portable Document Format) files. Thesis is focused mainly on middle-Europe languages. We designed, described and implemented program for this purpose. Besides the program and it's description the thesis contains information about PDF format object structure, it's syntax and logic necessary for proper understanding of text searching principles in PDF file. We also discussed filters, fonts and all other PDF Objects that the program need to process. This thesis also deals with methods and possibilities of improving program's functionality, speed, memory usage, reliability an universality of usage.

Application for Exam Preparation
Líbal, Tomáš ; Veigend, Petr (referee) ; Dytrych, Jaroslav (advisor)
This thesis deals with the issue of preparation of final exams at the Faculty of Information Technology of Brno University of Technology. It describes the process of design and implementation of a web application that allows teachers to create and manage room schemes and terms of individual exams. An important part of the application is also the automatic placement of students in the rooms and the generation of individual exam assignments for printing based on the given template and the method of placement. The application provides students with a clear view of individual exam terms and details about them. The work will result in a functional and usable web application written in Java using the Spring and Angular frameworks.

Vector Graphics Output from an HTML Rendering Engine
Chocholatý, Tomáš ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This thesis focuses on the issue of rendering web pages using vector graphics. The experimental CSSBox display engine and existing libraries for rendering vector graphics in PDF and SVG will be described here. The goal of the thesis is design a common structure for these two libraries and unify the process of rendering web pages in vector graphics as much as possible. Analysis of incorrectly implemented parts of existing solutions will be performed here and shortcomings, which will be necessary to implement to the resulting vector graphic meet the standard CSS3, will be describe. Furthermore, the implementation process, including the repair of all non-functioning original solutions, and the principle of unification of individual parts for the generation of both vector formats will be described. The conclusion is dedicated the results of self testing and outputs from generating real websites.

Extension of Apache Tika with Industrial File Formats Text Extraction
Rešetár, René ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
The goal of the bachelor's thesis was to extend the parsers of the Apache Tika project with data and table extraction from industrial document formats from laboratory instruments. These data will be stored in a structured format according to a certain scheme. In the theoretical part, the supplied industrial formats, the Apache Tika project and the possibilities of its expansion were examined. In the practical part, a tool was designed and implemented, which classifies documents using the Apache Tika project, processes them, creates structured data from them in the JSON format and subsequently validates them. Finally, a set of tests was created to verify and demonstrate the properties of the solution.

Filtering of Texts Extracted from PDF, OCR or Web
Lehnert, Filip ; Plchot, Oldřich (referee) ; Szőke, Igor (advisor)
The objective of this thesis is to implement a set of scripts to improve the transfer of various types of documents into fully text. There appears noise and not entirely correct character conversion by converting various file formats. These scripts extracted text file cleans so that the resulting text is readable, make sense and does not contain any residues of various characters appearing by the transfer of graphs, tables, formulas, etc. The script works universally and does not require input solely by OCR tools or converting from PDF or web.

Information System for a Care Service
Karásková, Kateřina ; Zendulka, Jaroslav (referee) ; Bartík, Vladimír (advisor)
Information system for a care service was inspired by the existing system. In there was created a new information system that eliminated shortcomings of the existing system. The information system enables to record data on employees, clients, care and payments for care. The system also includes an overview of past and future client care. The information system was implemented as a web application. This brings the benefit of accessing the application from any electronic device that has Internet access. The created information system can be extended by various functions, as needed by the care organization. The goal was to create an information system that would meet the needs of the care organization's employees and at the same time make it easier for employees to work.
