</div>This is handled by the GDAL EHdr driver.<br>
<br>
Looking at the code :<br>
* skipbytes: yes, taken into account<br>
* bandrowbytes: only taken into account if nbits < 8<br>
* totalrowbytes : only taken into account if nbits < 8<br>
<br>
Not sure why the last 2 fields are only taken into account conditionnaly.<br>
<br>
If that doesn't work for you, as suggested by Kyle, you could use<br>
VRTRawRasterBand specification.<br>
