Or in another way to ask. I want to know the <a href="http://dict.cn/mechanism" style="color:rgb(50,169,186);outline:none;text-decoration:none;font-weight:bold;font-family:Arial,Helvetica,sans-serif;font-size:14px;line-height:30px">mechanism</a> of it. Is that the mapserver first change the shp file to some type of image format(such as bitmap), then change it to png? (in <span style="font-family:Arial,sans-serif;font-size:14px">shp2img or other related method </span>).<div>
<br></div><div><div>I recently do an application that need to change a GIS vector format file to png file, and want to know should I first change to GIS vector file first to some type raster format, then use libpng to saved as png format and I think that maybe not a good method.</div>
<div><br></div><div> So I come here andI want to learn some process ways from mapserver , who know the <a href="http://dict.cn/mechanism" style="outline:none;color:rgb(50,169,186);text-decoration:none;font-weight:bold;font-family:Arial,Helvetica,sans-serif;font-size:14px;line-height:30px">mechanism</a> of mapserver processing like in "<span style="font-family:Arial,sans-serif;font-size:14px">shp2img</span>" method. </div>
