The main "innovation" in this patch are two "virtual buttons" for the record switch on YH92x targets. When the switch state changes, a single BUTTON_REC_SW_ON or .._OFF button event will be generated. Thus keymap code can react on switching, but not on the actual state of the switch. Wherever sensible, the following user scheme is applied: - use PLAY as confirm button - use REW button or Long REW to exit - use REC (YH820) or FFWD (YH92X) as modifier key for button combos Change-Id: Ic8d1db9cc6869daed8dda98990dfdf7f6fd5d5a1 |

this document describes how to add new image decoder. 1. create a directory which name is your image decoder's name and put source files under the directory. 'const struct image_decoder image_decoder' and 'IMGDEC_HEADER' must be declared in one of your source files. see imageviewer.h for the detail of struct image_decoder. 2. add the directory name to apps/plugins/imageviewer/SUBDIR so that the decoder is built. if the decoder is supported by particular targets, surround it with #if directive. e.g. if the decoder supports color LCD targets only, #ifdef HAVE_LCD_COLOR bmp #endif 3. append appropriate entry to enum image_type in image_decoder.h, decoder_names and ext_list in image_decoder.c so that the imageviewer plugin can recognize the decoder. if the decoder is supported by particular targets, surround them with same #if directive in SUBDIR. 4. add entry to apps/plugins/viewers.config (in format: file_extension,viewer/imageviewer) so that the file with specified file extension will be opened by image viewer plugin. if the decoder is supported by particular targets, surround it with same #if directive in SUBDIR. 5. add entry to apps/plugins/CATEGORIES (in format: decoder_name,viewer) so that the build file is copied to viewers directory. DON'T surround this with #if directive. notes: if you need to use greylib functions to draw image, add the functions to struct imgdec_api just like gray_bitmap_part because GREY_INFO_STRUCT is declared in imageviewer and is not available from the decoder.
