How to call this mode
Help for hex to bin conversion mode:
$ ./lcd-image-converter --mode=hex2bin --help
Usage: ./lcd-image-converter [options]
Tool to create image and font source files for embedded applications.
Options:
-h, --help Displays this help.
-v, --version Displays version information.
-m, --mode <mode> Conversion mode for application, "convert-image",
"convert-font" or "hex2bin".
-i, --input <path> Full <path> to image in *.C format.
-o, --output <path> Full <path> to output binary result.
Preset
- Image -> Prefix = “0x”
- Image -> Suffix = “”
- Image -> Delimiter = “ “
Template file for image
$(start_block_images_table)
le
uint16 $(out_image_width)
uint16 $(out_image_height)
uint16 $(out_blocks_count)
uint$(img_data_block_size) $(out_image_data)
$(end_block_images_table)
uint8, uint16, uint24, uint32 - data size.
le, be - bytes order, little endian or big endian.
Example
$ ./lcd-image-converter --mode=hex2bin \
--input=/temp/colors.c \
--output=/temp/colors.bin
“C” file after conversion to sources:
static const uint8_t image_data_colors[10] = {
0xd0,
0xf0,
0x90,
0xf0,
0xd0,
0xb0,
0xd0,
0xf0,
0x90,
0xf0
};
const tImage colors = { image_data_colors, 10, 5};
With modified template:
le
uint16 10
uint16 5
uint16 10
uint8 0xd0
0xf0
0x90
0xf0
0xd0
0xb0
0xd0
0xf0
0x90
0xf0
Binary file after conversion from hex to bin::

Other formats
From this binary file we can create files in variety of other formats. It is enough to take advantage of such a wonderful set of tools as SRecord.
