Re: [hugin-ptx] Scaling a PTO file ..
Bruno, thanks for your feedback on this.
I’ve modified you ptodouble to create ptoscale (see below). Will this work?
Feel free to do with this as you please.

[hugin-ptx] Scaling a PTO file ..
is there a script or program available that can scale the parameters in a PTO file? I’m thinking of the idea of using a lot of JPG images at 1600 pixels long side to set all CPs, masks, etc so it is quick for Hugin to process and create output images. I can then iterate through different settings/changes and quickly see what the output stitched image will look like. Then, when all looks well, I’ll recreate JPG (or TIFF) images from my raw images at original resolution (say 7360 pixels long side). It would be nice to then run a script on the PTO file that would scale all i, c, k, etc. lines and output a new PTO file that would work with the higher resolution images. For example: pto_scale —scale=7360/1600 —output=upscaled.pto trial.pto Has anyone done this?

[hugin-ptx] Hugin 2016.2 RC 1 released
Hi all, today we are releasing the Hugin 2016.2 rc 1. Source tarball can be downloaded at sourceforge: https://sourceforge.net/projects/hugin/files/hugin/hugin-2016.2/hugin-2016.2.0-rc1.tar.bz2/download or at launchpad: https://launchpad.net/hugin/2016.2/2016.2rc1/+download/hugin-2016.2.0-rc1.tar.bz2 Verify its checksums: md5: f77ce8a1dc0a337b99eca8fb8841e00d hugin-2016.2.0-rc1.tar.bz2 sha1: db9af9c228f83828d4c82b927140dcf3d9f4d5c7 hugin-2016.2.0-rc1.tar.bz2 This is a source code release. Users communities produce executables for their respective platforms. Please announce them here. (The rc 1 correspond to changeset 48cb11a23351 in our repository, which is also tagged as 2016.2rc1). Changes since beta 1 * More fixes for Mac OS build * Updated translations * More fixes for initialization of fast preview window * Cpfind: Improved finding of cp for float/double images by applying logarithm mapping to internal images Changes since 2016.0.0 * Allow reading of image positions from Papywizard XML files: First add the image to a new project and then select File, Import settings from Papywizard XML file... This will read the lens settings, the image positions and also, if applicable, the bracket settings. After this, the usual workflow is to run cpfind with --prealigned switch and then geocpset to connect orphanded images. * The internal blender and verdandi got the possibility to blend seams as alternative to current hard seam: For each seam the color of second image is adapted to the match the color of the first seam. For this blender, the blender order changes according to the overlap. The blending starts with the exposure anchor and blends then all overlapping images. This blending mode is not suited if there are bigger misalignments or bigger parallax errors. * The display of the control point error (after optimizing and in fast preview window) and the control point list window can now limited to take only control points in active images into account (menu Edit, Optimize only active images, connected with the setting on the optimizer tab). * Improvements to mask tab in Hugin (edit crop of all images of the same lens at once) and find panorama dialog in PTBatcherGUI (remove images from found panoramas, split found panorama into two). * Several improvements for Mac OS. * Fixes several issues with fast preview window which could result in random crashes (uninitialized variables, memory leaks). Upgrading from previous versions of Hugin should be seamless. If you do have problems with old settings, these can be reset in the Preferences window by clicking 'Load defaults'.
