Hi Milla,
: please visit this link below to show you what I mean:
: http://www.visamera.se/panoramas/GRASMATTA_PANO.htm
: My problem is: the original image is, as you can see, sharp but the image in the panorama is blurry and unsharp. Why?
Just zoom QuickTime out, to get the same scaled building as image has and you'll get about the same sharpness in the center of the viewer. Of course there is some loss of sharpness due to remapping of the image and blur on the edges of the viewer window (big FOV). All pano viewers suffer from this and QuickTime is not worse in the range.
Also image size is just 1000x500 pixels may be good for 240x160 window preview but not for 480x320 as you made.
Use larger images if you want to show it in bigger window!
: Not quite sure of what you meant in your answer...so to remove lens distortion (which probably causes the bluriness in the picture especially out in the edges) I put a,b and c values to 1? Is it possible for you to just write down the two first lines in the batch-script so that lens distortion is removed? Is there any other parameter in the script that controls the sharpness of the panorama? Is the panowindow perhaps too large?
This values are for removing of lens distortions like barrel, pincushion and correcting of some lens aberrations. It has nothing with blur you wrote above.
Use larger images to get sharper result (about 6000x3000 for full screen window)!
: I have only two more questions. Where in the script do I tell the player to show the controller? The autogenerated html-code does not show a controller.
: (So I have manually changed the script-generated html code to this "", but with the result that only half of the little greycontrolpanel is visible...) How do I change that?
Controller needs 16 pixels to be added to height as well.
: And what does
: "pixels sized tiles" (I quite don't understand the meaning of this...)do to the pano-quality ?
QuickTime movie has six cube faces (tiles) in to show your panorama. PanoCube autocalculates size of the tiles depends from panorama width. But always exists some fine tuners in this world who want to control everything - for them this feature exists. You can oreder exact size of cube faces through this parameter.
: Thanks, Milla - and thanks for answering questions about this program!
My pleasure to help you ;-)
