kmakepreview

syntax:

kmakepreview 1.1 (krpano.com - krpanotools 1.0.6)

    - makes a smooth panorama preview image

syntax: kmakepreview inputfiles [outputfile] [options]

 inputfiles ... jpeg or tiff input images 
                (only 8bit RGB or RGBA supported)
                spherical or cubical images, 
                cubical images should have a suffix like 
                _l,_r,left,front,... in their filename to 
                allow detection of the cubeside, otherwise 
                every image must be specified separately with 
                -l=.. -f=.. -r=.. -b=.. -u=.. -d=..

options:
-o=#            ... name of output image 
                    (jpeg or tiff, default=*preview.jpg)
-cs             ... save as cubestrip image 
                    (better quality)
-size=#x#       ... size of preview image 
                    (default=1024x512, 256x256 on -cs)
-smooth=#       ... preview smoothness 
                    (1-100; default=77)
-jpegquality=#  ... set jpeg quality 
                    (0-100; default=85)
-jpegsubsamp=#  ... set jpeg color subsampling 
                    (444,422,420,411; default=422)
-tiffcompress=# ... set tiff compression 
                    (none,lzw,zip,jpeg; default=lzw)
-q / -quiet     ... suppress output messages

This tool makes a smooth preview image. Smoothing with a normal "Image Editor" would not result the same. The problem of normal smoothing is that the zenit and nadir of the panorama are not smoothed correctly, and the left and right border won't be blended together.

• standard gaussian blur smoothing
• a kmakepreview - spherical preview image
• a kmakepreview - cubestrip preview image

Tutorials

1. Make a preview image from a spherical panorama image


this command makes the preview image "inputimagepreview.jpg"
click here for a example - spherical preview image



2. Make a cubestrip preview image from a spherical panorama image


this command makes the cubestrip preview image "inputimagepreview.jpg"
click here for a example - cubestrip preview image



3. Make a preview image from cubical panorama images (cubeside autodetection)


this command makes the preview image "cubepreview.jpg"
this is only possible in this way - because each filename has a suffix to identfiy the cube side.



4. Make a preview image from cubical panorama images (manual cubesides)


this command makes the preview image "preview.jpg"
each cube side is set separately!



5. Make only a little smooth cubestrip preview image


this command makes the preview image "sphericalimagepreview.jpg"



6. Set output image name


this command makes the preview image "mypreview.jpg"
