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?)
