OCR

This section groups all OCR specific configurations.

OCR__DEFAULT_LANG_CODE

By default Papermerge DMS will use language specified with this option to perform OCR. Change this value for language used by majority of your documents. For detailed list of three letter codes see 639-2/T column from ISO 639 2.

Example as environment variable:

PAPERMERGE__OCR__DEFAULT_LANG_CODE=spa

Default value is "deu":

PAPERMERGE__OCR__DEFAULT_LANG_CODE=deu

This options is used only when PAPERMERGE__OCR__AUTOMATIC=false.

OCR__LANG_CODES

List of comma delimited language codes to be displayed in UI. Note this is just UI configuration. Whatever codes you put here, it is your resposability to make sure that OCR worker does have those languages available.

Examples:

PAPERMERGE__OCR__LANG_CODES="eng,deu,fra,spa"
PAPERMERGE__OCR__LANG_CODES="eng, deu"
PAPERMERGE__OCR__LANG_CODES="ita, fra, ron"

Default value:

PAPERMERGE__OCR__LANG_CODES="deu,eng,ron"

This options is used only when PAPERMERGE__OCR__AUTOMATIC=false.

OCR__AUTOMATIC

When automatic is set to true - it means that OCR processing will be started without end user intervention (e.g. by means of some sort of OCR scheduling worker)

When automatic is set to false - it means that OCR will be performed only if requested by end user. In this case user can choose to start schedule OCR on upload; also in this case use can choose to schedule OCR later on any document as ofter as he/she wishes.

PAPERMERGE__OCR__AUTOMATIC=false is practical only in environments where end user is same as the one maintening Papermerge DMS instance, thus he/she owns computational resources and thus is not prone to abuse it.

Default value is:

PAPERMERGE__OCR__AUTOMATIC=false
