Ralph Little 311a38c76f brother_mfp: added first draft of man page for backend. 2023-12-11 13:05:54 -08:00
Ralph Little ceb7342877 brother_mfp: corrections for ADF cap flags and model definitions. 2023-12-11 13:02:32 -08:00
Ralph Little cc4ad6be99 brother_mfp: Added ADF duplex function for supported devices. 2023-12-11 13:02:32 -08:00
Ralph Little 4173926d3b brother_mfp: Added additional test suites for brother2 and brother3 
Also some encoder tests and general code tidy up.
 2023-12-11 13:02:32 -08:00
Ralph Little b64b8c13bb brother_mfp: Added support for source option. 
Can now select Flatbed or ADF for supported machines.
 2023-12-11 13:02:32 -08:00
Ralph Little ca760d54b3 brother_mfp: General tidy up ready for next stage. 2023-12-11 13:02:32 -08:00
Ralph Little a8a9e895b9 brother_mfp: added query block and error conditions 
Now detects cover open and paper jam.
Also formalised the query packet which occurs during initialization.
Hopefully, we will be able to decode this for useful information.
 2023-12-11 13:02:32 -08:00
Ralph Little 9bbf24cf97 brother_mfp: updated unit tests for changes to decoder API 2023-12-11 13:02:32 -08:00
Ralph Little 40de9f87b8 brother_mfp: added preliminary ADF multisheet support. 
I don't have a brother4 machine with an ADF so could not test this.
Quite a bit of refactoring to the encoder infrastructure to
accommodate this.
 2023-12-11 13:02:32 -08:00
Ralph Little d95166777f brother_mfp: added split resolution option 
By detail, user can now select a single resolution value or split x
and y resolutions with an additional "split resolution" option.

Default is to enable combine resolution.
 2023-12-11 13:02:32 -08:00
Ralph Little 76481920c3 brother_mfp: Added preview option. 
Also fixed some warnings that affected the pipeline.
 2023-12-11 13:02:32 -08:00
Ralph Little a484c6ad93 brother_mfp: added device cancel and compression option 
Some devices can compress colour (JPEG) and also provide raw data
in uncompressed form. The two devices that I have supply raw data
not in RBG but in YCbCr form.
Now applications have the option to choose compressed or uncompressed
colour scans if supported by the device.

Cancel from the device by pressing STOP is now handled properly.
 2023-12-11 13:02:32 -08:00
Ralph Little a6f4f816b1 brother_mfp: Added draft for brother3 driver. 
Test machine MFC-290C seems to support JPEG and RAW colour data.
However, the raw colour data has what appears to be a strong green
component leading to very green images. Maybe some post processing
is required to generate a proper image. Dunno. JPEG looks perfectly fine.
 2023-12-11 13:02:32 -08:00
Ralph Little fbe872ae86 brother_mfp: brother2 driver requires uncompressed gray decoder also 
Noticed in lineart output.
 2023-12-11 13:02:32 -08:00
Ralph Little 0055214614 brother_mfp: Added brother2 decoder + button support 
Also:
- Fixed major issue in gray decoder that caused data loss.
- Button support added for Brother2 decoder.
 2023-12-11 13:02:32 -08:00
Ralph Little 437bfd27f3 brother_mfp: colour scan now fully functional. 
Also:
- Init recovery for when previous crash left a session open.
- Small corrections for gray scans
 2023-12-11 13:02:32 -08:00
Ralph Little 3fae2e561d brother_mfp: corrected some decoding bugs. 
Still one rare illusive issue that causes loss of a bit of a line's
data, resulting in a sliding of the image to the left. It doesn't
happen very often, very difficult to reproduce.
 2023-12-11 13:02:32 -08:00
Ralph Little 22d8ab2b49 brother_mfp: first set of unit tests for decoder. 
Looks like we found the rare lost data issue in gray decoding.
Yayy! for unit tests.
 2023-12-11 13:02:32 -08:00
Ralph Little 6eb9e1cc43 brother_mfp: Added basic test framework and moved source into brother_mfp directory 2023-12-11 13:02:32 -08:00
Ralph Little 8280db1eef brother_mfp: compile out test scan dump to file. Also fix up some bugs. 
Hopefully, the fussy pipeline likes this version.
 2023-12-11 13:02:31 -08:00
Ralph Little 79a9b6ac44 brother_mfp: fixes to hopefully satisfy the pipeline. 2023-12-11 13:02:31 -08:00
Ralph Little 7f763c0763 brother_mfp: silence temp. parameter warnings upsetting the pipeline. 2023-12-11 13:02:31 -08:00
Ralph Little 4f060d6cea brother_mfp: fix for makefile and other small enhancements. 2023-12-11 13:02:31 -08:00
Ralph Little a7d6a553ee brother_mfp: First C++ draft. 
This version is a refactor using bits and pieces from the prototype.
Converted from C to C++ to make code reuse easier.
Will do gray/errdif/text scanning on the test MFC-J4320DW machine.
Cancel function added.
 2023-12-11 13:02:31 -08:00
Ralph Little a9853d1bb8 brother_mfp: first draft prototype 
Supports only grey/dithered_gray and text on MFC-4320DW.
Supports only USB.
