<p>ピクチャの画像を設定または変更するには、<strong>src</strong>メソッドを使用します。ピクチャのsrcには、base64画像を使用できます。</p>
<pre><code class="hljs js language-js"> picture.src(<span class="hljs-string">'images/spreadLogo.png'</span>);
<span class="hljs-keyword">var</span> originalWidth = picture.getOriginalWidth();
<span class="hljs-keyword">var</span> originalHeight = picture.getOriginalHeight();
picture.width(originalWidth);
picture.height(originalHeight);
</code></pre>
<p>ピクチャのレイアウトを変更するには、<strong>pictureStretch</strong>メソッドを使用します。ピクチャの伸縮方法は、<strong>ImageLayout</strong>列挙型で定義します。画像の元のサイズを取得するには、<strong>getOriginalWidth</strong>および<strong>getOriginalHeight</strong>メソッドを使用します。</p>
<p>ピクチャの枠線を追加できます。この枠線は、DOMの枠線設定として定義されます。次に、例を示します。</p>
<pre><code class="hljs js language-js"> picture.borderStyle(<span class="hljs-string">'solid'</span>);
picture.borderWidth(<span class="hljs-number">2</span>);
picture.borderColor(<span class="hljs-string">'red'</span>);
picture.borderRadius(<span class="hljs-number">4</span>);
</code></pre>
<p>ピクチャの一部が透明な場合は、背景領域の色を設定することもできます。ピクチャの背景色を取得または設定するには、<strong>backColor</strong>メソッドを使用します。次に、例を示します。</p>
<pre><code class="hljs js language-js"> picture.backColor(<span class="hljs-string">'green'</span>);
</code></pre>
