zbar-windows/TODO.md

general

• finish error handling
• handle video destroyed w/images outstanding
• dbg_scan background image stretched (still...)
• profile and weed out obvious oversights
• example using SANE to scan symbol(s)

windows port

• libzbar-0.dll should be zbar-0.dll

wrappers

• build API docs for zbargtk, zbarpygtk
• is zbargtk/QZBar BGR4 alpha swapped?
• widget config APIs
• drag-and-drop for widgets (configurable...)
• Perl build support integration?
• GTK and Qt perl bindings
• C++ global wrappers

symbologies

• PDF417
  • extract/resolve symbol matrix parameters (NB multiple symbols)
  • error detection/correction
  • high-level decode
• Code 39, i25 optional features (check digit and ASCII escapes)
• handle Code 128 function characters (FNC1-4)
• Code 128 trailing quiet zone checks

decoder

• start/stop/abort and location detail APIs (PDF417, OMR)
• more configuration options
  • disable for at least UPC-E (maybe UPC-A?)
  • Code-39/i25 check digit (after implementation)
  • Code-39 full ASCII (after implementation)
  • standard symbology identifiers (which standard?)
  • set consistency requirements
  • set scanner filter params
• fix max length check during decode
• revisit noise and resolution independence

image scanner

• extract and track symbol polygons
  • dynamic scan density (PDF417, OMR)
• add multi-sample array interface to linear scanner

image formats

• fix image data inheritance
• de-interlacing
• add color support to conversions (also jpeg)
• add support for scanline pad throughout
• factor conversion redundancy

window

• add XShm support
• X protocol error handling
• Direct2D
• API to query used interface (video, window?) (/format?)
• simple image manipulations scale(xv?)/mirror
  • maintain aspect ratio
• more overlay details
  • decoded result(?)
  • stats

zbarcam/zbarimg

• zbarimg multi-frame duplicate suppression
• stats/fps at zbarcam exit
• decode hook (program/script)? (also zbarimg?)
