透過色出力対応

2

- SIXELは仕様上、透過色を表現可能(alphaは無理) - libsixelの内部では単色カラーキーのインデックス番号を保持しているので、それにアクセスするAPIを公開するべき - img2sixel でも透過色対応を意識した読み方をするべき - 現時点で対応できそうな画像タイプ： - PNG/RGB/単色透過 - PNG/グレースケール/単色透過 - PNG/パレット/アルファ付き(tRNSチャンクからアルファ値が0のものを拾って一つの色にまとめる) - GIF/静止画像/単色透過 - libpng で読んできた場合、上記対応は可能 - stb_image で読んできた場合、ちょっと手を入れれば上記対応は可能 - gdk-pixbufやGD経由で読んできた場合はできるのかどうか、どうやればいいのか未調査 関連 Issue: #25

My working directory quickly fills with files like `test1.six` and `test-yyyymmdd.six`, so I made it easier to preview their contents in `explorer` and `Finder`. On `develop` branch, WIC decoder(Windows) and...

This patch adds a WIC (Windows Imaging Component) based image loader and a WinHTTP-based network backend (as an alternative to libcurl) for Windows builds. The WIC-based loader can be helpful...
