<div dir="ltr"><div><div><div>Hi List,<br></div>we are doing some performance tests with gdal operations (translate, warp, ...) and we are rewriting our output files as GeoTIFF with JPEG compression and YCBCR Photometric interpretation.<br></div>We would like to involve libjpegturbo on that so I have a couple of questions on the topic.<br></div><div>Before starting the new tests we have built a standard GDAL 2.1 version (on Centos 7) and did some "benchmarks".<br></div><div><br>Now we would like redo the tests using libjpegturbo.<br>1) Should we re-build GDAL once libjpegturbo is installed on the machine?<br></div><div>In that case, is there any explicit setting to be provided to ./configure or any output message from the ./configure confirming that libjpegturbo will be used?<br></div><div>2) is there any CPL_DEBUG similar env var to be configured to better know what is happening when running the gdal utilities in relation to the libjpegturbo usage?<br><br></div><div>I have already taken a look to the GDAL JPEG format page but it doesn't say too much.<br><i>"It is also possible to use the JPEG driver with the libjpeg-turbo, a
version of libjpeg, API and ABI compatible with IJG libjpeg-6b, which uses MMX, SSE,
and SSE2 SIMD instructions to accelerate baseline JPEG compression/decompression"<br></i><br>Thanks in advance.<br></div><div>Cheers,<br></div><div>Daniele<br></div><div><br clear="all"></div><div><div><div><div><br>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><span style="font-size:12.8px">==</span><br></div><div dir="ltr"><span style="font-size:12.8px">GeoServer Professional Services from the experts!
