This extract is subsampled using the ratio OR the output image Size.<h2>Parameters</h2><ul><li><b>[param] -in</b> <string> The image to read. Mandatory: True. Default Value: ""</li><li><b>[param] -out</b> <string> The subsampled image. Mandatory: True. Default Value: ""</li><li><b>[param] -rox</b> <int32> first point of ROI in x-direction. Mandatory: False. Default Value: "0"</li><li><b>[param] -roy</b> <int32> first point of ROI in y-direction. Mandatory: False. Default Value: "0"</li><li><b>[param] -rsx</b> <int32> size of ROI in x-direction. Mandatory: False. Default Value: "0"</li><li><b>[param] -rsy</b> <int32> size of ROI in y-direction. Mandatory: False. Default Value: "0"</li><li><b>[param] -sr</b> <int32> Sampling Ratio, default is 2. Mandatory: False. Default Value: "2"</li><li><b>[param] -sx</b> <int32> quicklook size in x-direction (used if no sampling ration is given). Mandatory: False. Default Value: "0"</li><li><b>[param] -sy</b> <int32> quicklook size in y-direction (used if no sampling ration is given). Mandatory: False.

Trying to subsampled huge JPEG200 image with the application will lead to poor performances for now.<h2>Authors</h2>OTB-Team<h2>See Also</h2> <h2>Example of use</h2><ul><li><p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">in: qb_RoadExtract.tif</p></li><li><p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">out: quicklookImage.tif</p></li></ul></body></html> |
