A document can be a PDF e-book, or a series of HTML files, or a series of video files, or a series of audio files, or a series of animated GIF files. The source catalog mentioned in this software product is organized according to the three-level structure of chapter, section and subsection of the book. All the materials needed to generate a document are stored as files in these directories. In the process of generation, the software will automatically read the material files in these directories to generate audio, video and e-book files. In the general directory, title_en.txt indicates the title of the document used to generate English videos, and title_en.txt indicates the title of the document used to generate English documents. Title files exist not only in the general directory, but also in several other levels of directories. Title files for documents in other languages exist in similar formats in various levels of directories. For details on which letters are used as language markers for a particular language, see the list of TTS languages in the TTS and Recording Options screen. When the TTS language is English, the title_en.txt file with a file name containing the zh flag will be used for generation. The rules for selecting other language-related text files in these directories are similar to those for title files.
A document consists of one or more chapters. Each chapter can be understood as a table of contents. Contains the chapter title file in the chapter directory. The software will automatically read the text string in the title file of the corresponding language version and display it in the video screen as the title.
Each chapter of a document contains one or more sections. Include the section title file in the program record.
A section of a document contains one or more sections. The section directory contains various material files in addition to the title files. All the materials needed to generate a document are of three types: images, text, and titles. Images are used to generate video images and ebook images. Each picture corresponds to a picture of the video. Text is used to generate speech data as well as PDF images and HTML text. The title will also appear in the video screen, PDF screen, and HTML screen. This software only supports JPG, PNG and TIF image files. If the image file is not JPG, it will be automatically converted to JPG image file. All text files used in this software must be UTF-8 encoded, otherwise they may not be parsed correctly or garbled. Two text files can be provided in the section directory, taking the English version as an example, image_en.txt is used to outline the image, the text information in this file will overwrite the image on the PDF page, so the text should be as brief as possible. The detail_en.txt file is used to describe the image in detail. The text information in this file will be in the form of a separate page in the PDF page, so you can use longer text in moderation. These two types of text are converted into sound data by TTS when generating audio and video, are converted into subtitles when generating video subtitles, and exist in the form of text when generating HTML files.
