<p>
This program allows you to edit the photo itself by entering the
photo name, path, filter type as parameters.<br />
Examples: changing the color of the photo, applying blur, and
mirror effects.<br /><br />
Language: C<br />
I have posted the code below for testing.<br />
</p>
<ol>
<li>
Create the files filter.c, helpers.c, bmp.h, and helpers.h in
the same folder.
</li>
<li>Parameters for filter effects:</li>
<ul>
<li>-b (Blur)</li>
<li>-g (Grayscale)</li>
<li>-r (Reflection)</li>
<li>-s (Sepia)</li>
<li>-e (Edge)</li>
</ul>
<li>Compile.</li>
<li>
Run the program with the command which is in the "How to use"
section. The parameter is set to -g.
</li>
</ol>
<h3>How to use</h3>
<p>Execute the following command to run the program:</p>
<p>./filter -g images/yard.bmp out.bmp</p>

<h3>写真フィルター・プログラム</h3>
<p>
プログラムにパラメーターとして写真名とパスを入れて、写真自体を編集する事が出来るプログラムです。<br />
例：写真の色を変えたり、ぼかし加工、ミラーエフェクトなど。<br /><br />
言語: C<br />
テストのため下にコードを載せました。<br />
</p>
<ol>
<li>
同じフォルダーにfilter.c、helpers.c、bmp.h、helpers.h、のファイルを作成する。
</li>
<li>フィルターエフェクトのパラメーター:</li>
<ul>
<li>-b (Blur)</li>
<li>-g (Grayscale)</li>
<li>-r (Reflection)</li>
<li>-s (Sepia)</li>
<li>-e (Edge)</li>
</ul>
<li>コンパイルする。</li>
<li>
このコマンドでプログラムを実行する。パラメーターは-gとなっています。
</li>
</ol>
