how to add new image sdecoder.
1. create a directory which name is your image decoder name and put source files
to the directory. e.g. bmp.
const struct image_decoder image_decoder and IMGDEC_HEADER need to be defined in
your souce file.
check imageviewer.h for the detail of struct image_decoder.
2. add the directory name to SUBDIR in this directory.
if your decoder is supported by particular targets, surround it with #if directive.
e.g. if the decoder supports color LCD targets only,
#if 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
4. add entry to the apps/plugins/viewers.config. e.g. bmp,viewer/imageviewer
if your decoder is supported by particular targets, surround it with #if directive.
e.g. if the decoder supports color LCD targets only,
#if HAVE_LCD_COLOR
bmp,viewer/imageviewer
#endif
notes:
if you need to use greylib functions to draw image, add the functions to
struct imgdec_api just like gray_bitmap_part.
