If the image's width or height 492 is not evenly divisible by the MCU block size (see <a href="../../../org/libjpegturbo/turbojpeg/TJ.html#getMCUWidth(int)"><code>TJ.getMCUWidth(int)</code></a> 493 and <a href="../../../org/libjpegturbo/turbojpeg/TJ.html#getMCUHeight(int)"><code>TJ.getMCUHeight(int)</code></a>), then there will be partial MCU blocks on the 494 right and/or bottom edges. It is not possible to move these partial MCU 495 blocks to the top or left of the image, so any transform that would 496 require that is "imperfect." If this option is not specified, then any 497 partial MCU blocks that cannot be transformed will be left in place, which 498 will create odd-looking strips on the right or bottom edge of the image.</div> 499<dl><dt><span class="strong">See Also:</span></dt><dd><a href="../../../constant-values.html#org.libjpegturbo.turbojpeg.TJTransform.OPT_PERFECT">Constant Field Values</a></dd></dl> 500</li> 501</ul> 502<a name="OPT_TRIM"> 503<!-- --> 504</a> 505<ul class="blockList"> 506<li class="blockList"> 507<h4>OPT_TRIM</h4> 508<pre>public static final int OPT_TRIM</pre> 509<div class="block">This option will discard any partial MCU blocks that cannot be 510 transformed.</div> 511<dl><dt><span class="strong">See Also:</span></dt><dd><a href="../../../constant-values.html#org.libjpegturbo.turbojpeg.TJTransform.OPT_TRIM">Constant Field Values</a></dd></dl> 512</li> 513</ul> 514<a name="OPT_CROP"> 515<!-- --> 516</a> 517<ul class="blockList"> 518<li class="blockList"> 519<h4>OPT_CROP</h4> 520<pre>public static final int OPT_CROP</pre> 521<div class="block">This option will enable lossless cropping.</div> 522<dl><dt><span class="strong">See Also:</span></dt><dd><a href="../../../constant-values.html#org.libjpegturbo.turbojpeg.TJTransform.OPT_CROP">Constant Field Values</a></dd></dl> 523</li> 524</ul> 525<a name="OPT_GRAY"> 526<!-- --> 527</a> 528<ul class="blockList"> 529<li class="blockList"> 530<h4>OPT_GRAY</h4> 531<pre>public static final int OPT_GRAY</pre> 532<div class="block">This option will discard the color data in the input image and produce 533 a grayscale output image.</div> 534<dl><dt><span class="strong">See Also:</span></dt><dd><a href="../../../constant-values.html#org.libjpegturbo.turbojpeg.TJTransform.OPT_GRAY">Constant Field Values</a></dd></dl> 535</li> 536</ul> 537<a name="OPT_NOOUTPUT"> 538<!-- --> 539</a> 540<ul class="blockList"> 541<li class="blockList"> 542<h4>OPT_NOOUTPUT</h4> 543<pre>public static final int OPT_NOOUTPUT</pre> 544<div class="block">This option will prevent <a href="../../../org/libjpegturbo/turbojpeg/TJTransformer.html#transform(byte[][],%20org.libjpegturbo.turbojpeg.TJTransform[],%20int)"><code>TJTransformer.transform()</code></a> from outputting a JPEG image for this 545 particular transform.
