TGA

TARGA image format support for the D programming language.

The library provides simple data types (Pixel, Image etc.) that might come in handy whenever image processing or synthesis is required. A set of functions to manipulate those types (I/O, transforms and more) is also included.

The library currently supports any combination of the following:

• grayscale, color-mapped and true-color images,
• 8, 16, 24 and 32 bit color depth,
• raw and RLE format.
• image origin, pixel order.

Installation

The project is built using dub and can be used as a package dependency:

{
    "dependencies": {
        "tga" : ">=0.1.0"
    }
}

Usage

Basic usage includes reading images, manipulating the pixel data, saving the image in a specified format or creating an image entirely from scratch.

Reading and processing image

import tga;

File inFile = File("input.tga");
Image img = readImage(inFile);

/* process the image in some way */
process(img.pixels, img.header.width, img.header.height);

File outFile = File("output.tga");
writeImage(outFile, img);

Generating an image

import tga;

/* generate pixels in some way */
Pixel[] pixels = generateImage(width, height);

Image img = createImage(pixels, width, height, ImageType.COMPRESSED_TRUE_COLOR, pixelBitDepth);

File outFile = File("output.tga");
writeImage(outFile, img);
