Hi,<br><br>I´ m using Gdal 1.9 and trying to realize a polynomial transformation using GDALTransformerFunc.<br><br>I wanna use <a class="" href="http://www.gdal.org/gdal__alg_8h.html#a7df61123fec15deb3da3acabce19e647" style="color:rgb(70,101,162);font-weight:bold;text-decoration:underline">GDALTransformerFunc</a> to perform the transformation.<br>
<br>The documentation says that the first argument (<span class="">void</span> *pTransformerArg) is a callback data function. <a class="" href="http://www.gdal.org/gdal__alg_8h.html#ac57c80f7bf6752fac1dff8c2a21a15a3" title="Create GCP based polynomial transformer.">GDALCreateGCPTransformer()</a> <span id="result_box" class="" lang="en"><span class="">serves as callback data function for GDALTransformerFunc?<br>
<br>Is there any way to obtain the coefficients of the polynomial transformation?<br><br>Regards,<br></span></span><br>---<br><span><font color="#888888">Gabriel Fusca<br>SUR Emprendimientos Tecnológicos<br><br>Perú 345 Piso 5to Oficina "B" (C1067AAG)<br>
