Download

Download OCR Manga Reader via SourceForge

Confused about which .apk file to download? Most users should download OCR_Manga_Reader_v6.0.apk (it supports devices with the armeabi-v7a architecture - this architecture is by far the most common). Users with a device that has the less common x86 architecture should download OCR_Manga_Reader_v6.0_x86.apk.

How to Install a .apk File

  1. First you need to enable the "Unknown sources" option to install apps outside of the Play store. It's done like this: Settings > Security > Unknown sources.
  2. Download the OCR Manga Reader .apk from SourceForge to your device.
  3. Using an Android file manager (such as ES File Explorer) tap the .apk file you just downloaded and then tap Install.

How to Enable the Optional Name Dictionary

  1. Download the name dictionary (enamdict.sqlite) from SourceForge.
  2. Copy the name dictionary to <sdcard>/Android/data/com.cb4960.ocrmr/files/
  3. Force stop and then restart OCR Manga Reader.
  4. The next time you OCR some text, entries from the name dictionary will appear after all of the normal dictionary entries in the Dictionary Panel. You may need to scroll down to see them.

How to Enable the Optional Kanji Dictionary

  1. Download the kanji dictionary (kanji.dat) from SourceForge.
  2. Copy the name dictionary to <sdcard>/Android/data/com.cb4960.ocrmr/files/
  3. Force stop and then restart OCR Manga Reader.
  4. The next time you OCR some text, entries from the kanji dictionary will appear after all of the normal dictionary entries in the Dictionary Panel. You may need to scroll down to see them.

By default, only the meanings of the kanji will be shown in the definition area. To set a custom format:

  1. Create a file called kanji_def_format.txt and place it in <sdcard>/Android/data/com.cb4960.ocrmr/files/
  2. Edit kanji_def_format.txt and specify the format using one or more of the following tokens:
    Token Description

How-To ...

Word Frequencies

The lower the number, the more frequent the word. All words that share the same frequency are members of the same frequency group. So if a word belongs to frequency group 1563, it means that there exist 1562 frequency groups that are more frequent. Colors of the frequency numbers: very common words are green-ish, common words are yellow-ish, uncommon words are orange-ish, rare words are pink-ish. Frequencies are based on analysis of 5000+ novels. Naturally, frequency based on other mediums (such as newspapers) might vary. Not all words have frequency information. When the frequency is based on the reading, and the expression and reading differ, "_r" will be appended to the end of the frequency number to indicate that the frequency number was based on the reading.

Substitutions (advanced)

Sometimes OCR Manga Reader consistently makes the same OCR mistakes such as recognizing a "か" as "カゝ".

By editing <sdcard>/Android/data/com.cb4960.ocrmr/files/substitutions.txt you may tell OCR Manga Reader to substitute one text string for another text string.

You may add one substitution per line in this format:

from_text=to_text

Example:

カゝ=か
︿=く
\|二=に

Special tokens and escape characters:

%eq% Equals (=)
%perc% Percent sign (%)

You may disable a substitution by adding a "#" in front.

When done editing substitutions.txt, restart OCR Manga Reader.

Known/Todo word lists (advanced)

OCR Manga Reader will display an indicator to the right of a word's reading if that word appears in your list of known words or todo words (words that you don't know yet, but want to learn).

The list of known words must be named known_words.txt and must be placed at <sdcard>/Android/data/com.cb4960.ocrmr/files/known_words.txt.

The list of todo words must be named todo_words.txt and must be placed at <sdcard>/Android/data/com.cb4960.ocrmr/files/todo_words.txt.

By default, neither of these files exists. You will have to create them.

Place exactly one word on each line.

If the word appears in known_words.txt, a * indicator will appear.

If the reading of the word apears in known_words.txt, a *r indicator will appear.

If the word appears in todo_words.txt, a *t indicator will appear.

If the reading of the word appears in todo_words.txt, a *tr indicator will appear.
