texconv 1.0.0

texconv is a utility for creating textures for the SEGA Dreamcast hardware.

Requires Qt 5.2 or newer.

Supports all image formats supported by Qt.
At the time I'm writing this, these formats are supported:

Format    Description                                Qt's support
BMP        Windows Bitmap                            Read/write
GIF        Graphic Interchange Format (optional)    Read
JPG        Joint Photographic Experts Group        Read/write
JPEG    Joint Photographic Experts Group        Read/write
PNG        Portable Network Graphics                Read/write
PBM        Portable Bitmap                            Read
PGM        Portable Graymap                        Read
PPM        Portable Pixmap                            Read/write
XBM        X11 Bitmap                                Read/write
XPM        X11 Pixmap                                Read/write

USAGE
=====

texconv --in <filename> --out <filename> --format <pixelformat> [flags...]

EXAMPLES
========

texconv --in img.jpg --out a.tex --format RGB565
    Creates an RGB565 texture called 'a.tex' using 'img.jpg' as input.

texconv --in img.jpg --out a.tex --format PAL8BPP
    Creates an 8-bit paletted texture called 'a.tex' using 'img.jpg' as input.
    A palette file 'a.tex.pal' will also be created.

texconv --in img.jpg --out a.tex --format YUV422 --compress --mipmap
    Creates a compressed, mipmapped YUV texture 'a.tex' using 'img.jpg' as
    input.

texconv --in img1.jpg --in img2.png --format RGB565 --mipmap
    Also assuming "img1.jpg" is 64x64 and 'img2.png' is 16x16, creates a
    mipmapped RGB565 texture with mipmap levels like this:
        64x64 - 'img1.jpg'
        32x32 - 'img1.jpg' (downscaled)
        16x16 - 'img2.png'
          8x8 - 'img2.png' (downscaled)
          4x4 - 'img2.png' (downscaled)
          2x2 - 'img2.png' (downscaled)
          1x1 - 'img2.png' (downscaled)

texconv --in img.jpg --out a.tex --format PAL4BPP --compress
        --preview preview.png --vqcodeusage usage.png
    Creates a compressed 4-bit paletted texture 'a.tex' using 'img.jpg' as
    input. A palette file 'a.tex.pal' will also be created. A preview file
    'preview.png' showing what the texture looks is generated as well as
    an image 'usage.png' that visualizes codebook usage for 'a.tex'.
