i2a

A tool for converting images and C arrays to each other. i2a is implemented by ANSI C, it can be compiled and used on Linux, OSX, Windows, *nix.

Features

• Convert BMP file to C array.
• Convert C array to BMP file.
• Currently, only the RGB16(RRRRRGGGGGGBBBBB (2byte/pixel)) is supported.
• Currently, only the BMP(24 bit full color) is supported.

Build

cd i2a
mkdir build
cd build
cmake ..
make

Usage examples

Convert C array to BMP file:

$ i2a a2b your_c_array.h rgb16 800 600 24

$ write BMP file ok. your_c_array.h.bmp

Convert BMP file to C array:

$ i2a b2a your.bmp rgb16 > your_c_array.h

help:

$ i2a

$ Usage: i2a <mode> <file path> <color mode> <width> <height> <color bit count>
$     <mode>: a2b or b2a
$         a2b: Convert C array file to BMP file.
$         b2a: Convert BMP file to C array file.
$     <file path>: C array file or BMP file.
$     <color mode>: The color mode of each pixel in the array. Now only supports the following formats:
$         rgb16: RRRRRGGGGGGBBBBB (2byte/pixel).
$     <width>: Image's width. Mandatory in a2b mode.
$     <height>: Image's height. Mandatory in a2b mode.
$     <color bit count>: Color depth of BMP file. Mandatory in a2b mode. Now only supports the following formats:
$         24: 24 bit full color.

Only one array is allowed in "c_array.h". The format of "c_array.h" example:

static const uint16_t bmp_arr[] = {
    0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF,
    0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF,
    0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF,
    0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF,
    0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF}
