Building

  • Open NovelTool.sln with Visual Studio(Community also available) and built with .Net Framework 4.8.

Supported file formats

  • Epub (*.epub)(Experimental feature)
    EPUB is an e-book file format that uses the ".epub" file extension. The term is short for electronic publication and is sometimes styled ePub.

  • Aozora (*.txt)(Experimental feature)
    Aozora Bunko (青空文庫, literally the "Blue Sky Library", also known as the "Open Air Library") is a Japanese digital library.

  • Text Image(*.bmp; *.jpg; *.gif; *.png)
    Novel eBook images or scanned image files.

Getting started

  1. Open the folder or zip(*zip; *.rar; .7z) of novel/eBook file(.epub; *.txt; *.bmp; *.jpg; *.gif; *.png;), analyze image content immediately, If you open the compressed format, it will be decompressed in the same directory.
  2. Wait for the analysis of the novel/eBook results to be completed.
  3. Maybe you need to change the option settings, when the analysis result is wrong. Re-analyze the novel/eBook file after changing settings.
  4. Now execute GenerateView from the toolbar to confirm the generated content.
  5. The size of the output text image can be changed.
  6. Execute save or save all to save the generated content as a new image file, and wait for a while depending on the number of pages generated.

Analysis Novel

  • Parse the novel/eBook image file sequentially from the vertical direction and detect the position of the text.
  • Analysis results can be viewed in the main window.
  • If there are analysis results in the illustration, you needs to be unchecked.

Generate View

  • In GenerateView, based on the analysis results, convert the image font size according to the specified output resolution.
  • Here are some built-in image filtering features, the more useful ones are Sharpen, the rest are just for testing.
  • Immediately view the results of changing image font size or filter options.
  • After confirming that the generation is correct, execute save (current page) or save all.

Option settings

Analysis

  1. AnalysisFactor

    • AnalysisTaskThreadLimit: Determines the maximum number of threads to perform analysis tasks (Default 2).

    • IgnoreMinDetectYSize: Decided to ignore top and bottom widths when detecting images (Default 3, if there is non-text content on the edge).
    • IgnoreBrightness: Determine the brightness value, when the brightness of the pixel exceeds this value, it is not detected, 1.0 represents white (Default 0.9).

    • IllustrationRate: none
    • EntityMinRate: Determines the scale value of the smallest text (rubi characters/ルビ) when the standard text scale is 1 (Default 0.6).
    • EntityMaxRate: Determines the scale value of the largest text (parsable as standard text) when the standard text scale is 1 (Default 1.2).
    • EntityAdjacentRate: Determines the minimum scale value that is immediately adjacent between two lines (Default 0.2, for example standard text and rubi characters).
    • EntityMergeTBMaxRate: Determines the scale value that can be merged into a one character, when a character is broken by wrong analysis (Default 1, for example 元, 二, 言...).

  3. Confirm

    • IllustrationMinColorsLevel: Determine the minimum number of colors for illustrations that can be detected as non-text (Default 2000, duplicate colors are not counted).
    • IllustrationMinNonWhiteLevel: Determine the minimum number of foreground colors for illustrations that can be detected as non-text (Default 800000).
    • WhiteLevel: Determines the color value detected as the background(white) color (Default 240).
    • HeadGap: Determines the minimum height of the top margin above the header (Default 15).
    • FooterGap: Determines the minimum height of the bottom margin below the footer (Default 15).
    • EntityHeadGap: This value is related to determining whether it is the first word of the line (Default 0).
    • EntityEndGap: This value is related to determining whether it is the end of the line (Default 0).
