Updates

Each release with new functionality has a increased version number. The prefix a,b,.. following the version number means the same version with known bugs fixing.

v. 1.103 -The program has been translated on new base libraries versions of OpenCV and ImageMagick. This allowed to apply new more effective mechanisms of image recognition and construction.
- Added a new alignment mechanism based on using generated stars map in the image. The number of detected stars is determined by the user itself. Star map may be saved as separate file.
- Improved UI and fixed known bugs including those affecting on aligning and calibrating a series of images.
v. 1.102 -Online registration and activation of PGMania is now available! Use direct link in programm for this.
- Adding support for most of known DSLR image types.
- Improved functionality and speeds, redisigned interface.
- Known bugs fixed and code refactoring was done.
v. 1.101 -Added reducing image size alghrithm for better recognition functionality while aligning image pairs.
- Added max offset limits for image displacement and rotation while auto aligning images pairs. Limits can be set for each image or for whole folder.
- Added more flexible analisys for estimate aligning results. Only well aligned and fitted images are allowed to calibration and stacking.
v. 1.100 -Added resizing images for a new size in pixels or to percentage of original image size.
v. 1.099 -Added more automation to aling and calibration processes, improve performance and usability.
Added maintenance of operations list with image files and information storing about master images used while processing the image pair. It is easy to see and restore processing history.
'Serial' stack and 'In pairs' stack algorithms now uses SNR analizes for optimal stacking and use images sorting based on SNR values while stacking to optimise the final result.
Known bugs fixed and code refactoring was done.
v. 1.098 -Added one more algorithm for calibration - 'Selective'. It uses both 'And' algorithm and 'Or' algorithms for each calibrating images pair,
analizing the resulting images for ghosts, fwhm and SNR, and taking the best resulting images pair -
one calibrated image from 'And' algorithm and another calibrated image from 'Or' algorithm).
v. 1.097 -Added one more algorithm for align and calibrate image series via setting reference points in images.
Detecting algorithms improved functionality and speeds. Also increased its recognition reliability.
Added fixing histogram settings for all folder images. Each image stores its own settings which can be switched or replace by the common folder settings.
v. 1.096 -Added ability for dragging image inside window for viewing in full size mode and zoom mode.
Added image contrast tuning and ability to create image mask via setting transparency for black.
Fixed known bugs, been improved processes for work with detected stars and more.
v. 1.095 -Added calculating of fwhm, snr and star magnitudes for detected stars and average fwhm/snr for whole images.
Added fields for image resolution and pixel size. This settings used in this calculations.
Added ability to set desired magnitude for any reference star and recalculate stars statistics.
Added ability to flip images horisontally or vertically.
Added showing a histogram for any of selected star from detected stars list or for a star selected at image.
v. 1.094 -Added stars detection for any deep sky image. Added ability to composite original image with a star map.
Added list with detected stars and ability to mark a star from a list on the star map. Also it is possible to find a star in list by click it directly on the image.
XML log file now created for every folder you work with. Log contains description for last operationwith image, used master image, operation results, image offsets and detected stars list.
Added ability to add any text markers to the image with a font size you like.
Added easy to use direct saving of original image with applying its histogram adjustments and align movements to a new file with a similar name.
Added ability to make a full frame screenshot with detected stars and user text markersplaced on the image.
v. 1.093 -Added export to XML and restore from XML image/histogram settings and results/operation settings for align/calibrate operations.
v. 1.090 -Added stacking image series in several modes, such as serial stacking, stacking in pairs and IM evaluate algorithms. All methods uses filtering and histogram correction of intermediate stacking stages. Added post processing images using alive histogram control for image contrast stretching.
v. 1.089 -Added processing for auto align and calibrate image series in several modes. Added operations logging. Added statistics with cordinates and brightnes for detected stars.
v. 1.088 -Added some changes to interface and usability. Perfomans for auto aligning and calibration was enhanced. Fixed b
ug with fitting some image formats while auto aligning and/or calibrating images(16bpp fits, pgm, etc.)..v. 1.087 -Added auto align, fit and calibrate images using rotations and direct displacements.v. 1.086 -Added one more image calibration algorithm.v. 1.084 -Added functionality for auto align and calibrate images (w/0 rotations).v. 1.081 -Added functionality to create composite of manually aligned images.v. 1.080 -Added functionality for manual calibrating of 2 close images by pairs. Calibration removes dust, noise and hot pixels from both of images. No need for dark, flat or bias files more. Enjoy it.v. 1.070 -Added functionality for manuall align'g images using the master frame. The image may be moved and/or rotated concerning reference image. v. 1.061 -Added ability for single/multi image conversion from one image format to another. algorithms for image sequence constructing were optimised and speeded. v. 1.06 - Added functionality for converting image files from one format to another. Supports batch converting operations for image sequence. Image formats can be any of well known, for example: .pgm, .fits, .tiff, .jpeg, .gif, .psd, etc. v.1.04 -Added support for RawVideo, which makes it possible to obtain AVI to RawVideo format directly from the photo series, suitable for direct work with programs such as Autostakkert and so forth. Thus eliminating the need for intermediate conversion 16 bit AVI to SER. However, for Raw video frame written in 16bpp format Y800, or as RGB555, and that formats with 8 bits, making Raw video format is of little use if the source code of 16 bits.PGMania help & documentationThe author knows only the basic English and that is why he looks for volunteers and helpers - the native speakers to translate the documentation of the program in other languages, such as English, German, French, Chinese, and others.As a PGMania program is not commercial and is free for distribute, this work is not paid by author.We would appreciate for your assistance in the translation.For our part, we can guarantee possible consultations and assistance in learning the program's abilities.Nowadays detailed instructions and documentation available in Russian only. We apologize for the inconvenience.What next?A new version is under construction. The features and improvements includes new images aligning algorithms, analyses and calculations and more.The new version will be available soon.Keep for updates!Important notes You may have a troubles while reading some image formats via PGMania. PGMania uses ImageMagick engine to show images. IM may use some external libraries, such as Dcraw, etc., to operate some specific types of images.For example DSLR Raw images like Canon .CR2, Nikon .Nef and so on. IM uses delegates.xml file to find a known nonresident programs for operate with this types of files. This file contains links to external programs and libraries which are used by ImageMagick to operate with non resident image types.Ckeck the presence of delegates.xml in PGMania folder and edit it for your own purposes.If you have not this file, download "delegates.xml" and put it in the PGMania folder.The programs described in delegates.xml must be placed in the PGMania folder or in the PGMania/Lib folder.See morehttp://www.imagemagick.org/Usage/files/#delegateshttp://www.imagemagick.org/download/delegates/InstallationDownload and unpack archive, create shortcut for PGmania.exe and place it to desktop. PGMania require .Net 4.0 to be installed and FFMpeg library (they included in archive).For any questions please contact the author at pgmania@yandex.ruEnjoy it.The author:Eugene Trifonoff, aka p.v. /Pterodactilus Vulgaris/ E-mail: pgmania@yandex.ru Saint-Petersburg / Vyborg, RussiaFFmpeg is a trademark of Fabrice Bellard, originator of the FFmpeg project.
