Interlacing is usually used to 1287make image information available to the user faster by taking 1288advantage of the space vs time tradeoff. For example, interlacing 1289allows images on the Web to be recognizable sooner and satellite 1290images to accumulate/render with image resolution increasing over 1291time. 1292</p> 1293<p style="margin-bottom: 0in">Use <i>LineInterlace</i> or 1294<i>PlaneInterlace</i> to create an interlaced GIF or progressive JPEG 1295image. 1296</p> 1297<p style="text-align:center;margin-bottom: 0in"><b>InterlaceType</b></p> 1298<table width="100%" border="1" cellpadding="1" cellspacing="1" bgcolor="#cccccc"> 1299 <tr> 1300 <td> 1301 <p style="text-align:center"><b>Enumeration</b></p> 1302 </td> 1303 <td> 1304 <p style="text-align:center"><b>Description</b></p> 1305 </td> 1306 </tr> 1307 <tr> 1308 <td> 1309 <p>UndefinedInterlace</p> 1310 </td> 1311 <td> 1312 <p>Unset value.</p> 1313 </td> 1314 </tr> 1315 <tr> 1316 <td> 1317 <p>NoInterlace</p> 1318 </td> 1319 <td> 1320 <p>Don't interlace image (RGBRGBRGBRGBRGBRGB...)</p> 1321 </td> 1322 </tr> 1323 <tr> 1324 <td> 1325 <p>LineInterlace</p> 1326 </td> 1327 <td> 1328 <p>Use scanline interlacing (RRR...GGG...BBB...RRR...GGG...BBB...)</p> 1329 </td> 1330 </tr> 1331 <tr> 1332 <td> 1333 <p>PlaneInterlace</p> 1334 </td> 1335 <td> 1336 <p>Use plane interlacing (RRRRRR...GGGGGG...BBBBBB...)</p> 1337 </td> 1338 </tr> 1339 <tr> 1340 <td> 1341 <p>PartitionInterlace</p> 1342 </td> 1343 <td> 1344 <p>Similar to plane interlaing except that the different planes 1345 are saved to individual files (e.g. image.R, image.G, and image.B)</p> 1346 </td> 1347 </tr> 1348</table> 1349<p style="margin-bottom: 0in"><br /> 1350</p> 1351<table width="100%" border="0" cellpadding="1" cellspacing="1"> 1352 <tr> 1353 <td bgcolor="#52799e"> 1354 <p align="left"><a name="ChannelType1"></a><img src="right_triangle.png" name="Graphic14" alt=">" align="bottom" width="15" height="14" border="0" /><b><font size="4"><font face="Helvetica, Arial"><font color="#ffffff">ChannelType</font></font></font></b></p> 1355 </td> 1356 </tr> 1357</table> 1358<p style="margin-bottom: 0in"><i>ChannelType</i> is used as an 1359argument when doing color separations.
