<p>Hi there,</p>
<p><br>
</p>
<p>I am trying to use C API defined in gdal_utils.h.</p>
<p><br>
</p>
<p>By reading the RFC 59.1 I understand that the SWIG wrappers will have a nice interface to pass the parameters [1], ex.:</p>
<p></p>
<pre class="wiki"> format --- output format ("GTiff", etc...)
outputType --- output type (gdal.GDT_Byte, etc...)
bandList --- array of band numbers (index start at 1)
srcWin --- subwindow in pixels to extract: [left_x, top_y, width, height]</pre>
<p>But it seems like for C, the only way to pass the parameters will be by passing "char** papszArgv" in the same fashion as GDAL command line.</p>
<p></p>
<br>
<p></p>
<p>That doesn't seems to be fair with poor C programmers like me. We would need to translate things like "format=XXX" to "-of XXX" and "outputType=XXX" to "-ot XXX" for all the options and all the utilities.</p>
<p><br>
</p>
<p>The GDALTranslateOptions is opaque [2], so we cannot access it's member either. See commented line and the error message:<br>
</p>
<p><br>
</p>
<p><span style="font-family: "Courier New",monospace;"> GDALTranslateOptions* psOptions = GDALTranslateOptionsNew( papszArgv, NULL );</span></p>
<p><span style="font-family: "Courier New",monospace;"></span><br>
</p>
<p><span style="font-family: "Courier New",monospace;">// psOptions->pszFormat = pszOutDriver; // error: dereferencing pointer to incomplete type</span></p>
<p><span style="font-family: "Courier New",monospace;"></span><br>
</p>
<span style="font-family: "Courier New",monospace;"> hDstDataset = GDALTranslate(</span><br>
<span style="font-family: "Courier New",monospace;"> (const char*) pszOutFilename,</span><br>
<span style="font-family: "Courier New",monospace;"> (GDALDatasetH) hSrcDataset,</span><br>
<span style="font-family: "Courier New",monospace;"> (const GDALTranslateOptions*) psOptions,</span><br>
<p><span style="font-family: "Courier New",monospace;"> (int*) NULL );</span></p>
<p><span style="font-family: "Courier New",monospace;"></span><br>
</p>
<span style="font-family: "Courier New",monospace;"> GDALTranslateOptionsFree( psOptions );</span><br>
<br>
<p>Is there any other way to pass the parameters to the GDAL "Utilities as Libraries" in C?<br>
</p>
<br>
<p>Thanks,</p>
<p>Ivan<br>
