手作り画像圧縮ソフト Handmade image compression software

Processingで作った手作り画像圧縮ソフトです。

PNG、ZIF、JPEG、BMP形式の画像を圧縮することができます。

拡大すると、ドット絵に見えます。
拡大せずに見ると、何も変わっていないように見えますが、中間色で見えるため、目の錯覚で変わっていないように見えるのです。

256色しか使わない画像に変換します。BMPならば、3分の1のサイズになります。

Windows32ビット用、64ビット用、Mac用を作りました。

It is handmade image compression software made with “Processing”.

PNG, ZIF, JPEG, BMP format images can be compressed.

When you magnify, it looks like a dot picture.
Looking without enlargement, nothing seems to have changed, but it looks like a neutral color, so it looks like it has not changed with the illusion of the eye.

It converts to an image that uses only 256 colors. If BMP, it will be one-third the size.

I made Windows 32 bit, 64 bit, Mac.
