Please update to the new version, I fixed this issue.
from tga.
Can you list your code and the tga file?
from tga.
var TGA = require("tga");
const maps = "./maps/";
var fs = require("fs");
var PNG = require("pngjs").PNG;
// Delete ds store before start
fs.readdir(maps, function (err, filenames) {
filenames.forEach(function (filename) {
console.log(maps + filename);
var tga = new TGA(fs.readFileSync(maps + filename));
var png = new PNG({
width: tga.width,
height: tga.height,
});
png.data = tga.pixels;
png.pack().pipe(fs.createWriteStream(`${maps}${filename}.png`));
});
});
from tga.
You tga image's alpha channel are all 0, so the output png file is empty!
Maybe you can reset the alpha channel as 255 by the code below:
for (var i = 3; i < tga.pixels.length; i += 4) {
// change alpha channel as 255
tga.pixels[i] = 255;
}
