PGMania 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. 1.122 - Added operation for prepare images to create mozaic (panorama). First you should align source images and get offsets over master image. Then do "Mozaic prepare" operation over aligned images. This will create a new images with equal enlarged size bounds common for all images. Source images shifts inside this bounds with previously calculated offsets so that no one of them do not cross the new bounds. After this you are able to stack prepared images and get the final mozaic (panorama) summ image.
v. 1.121 - The application layout has been redesigned, the working area of the image has been expanded, the controls and settings have been optimized.
Fixed bugs in working with XML files while changing working folder, eliminated cases of incorrect offsets calculation for some images.
Today PGMania carries out 100% automated aligning with 100% high-quality results. A pixel-by-pixel accuracy of combining images in all modes is achieved.
Thanks for all PGMania users for patience and expectation. It was not an easy task, but now it is done!
v. 1.120 - Remastered manual operations for correction of automatically calculated offsets for more accurate aligning of images. The correction is stored and displays separately from the offsets and summed with them during the “Apply offset correction” operation. Total offsets will still stored in aligned images for subsequent pairwise calibration operations. For details see the help section about offsets.
v. 1.119 - Added batch image processing has been added to reflect images vertically, horizontally, to rotate 180 degrees, to actualize virtual offsets and use the histogram settings, to normalize the histogram and to invert to negative. All of this now working for any selected images.
- The image alignment algorithm based on the use of homography relationships between images has been fixed and revised.
- Added normalization option for align operations that use star detection. Increased productivity and reliability of alignment results using homography. Known bugs were fixed.
v. 1.118 - Completely redesigned alignment algorithms. A new basic algorithm for determining stars and offset calculations based on original authoring algorithms has been added.
New functions for offset correction and offset transfer between operations are added, the default color scheme setting at the first start and some new functions in the interface are added.
Significantly increased the overall reliability of automatic recognition and calibration of images (close to 100%), also increased the overall speed of the application and fixed known bugs.
Added a mechanism for tracking the release of new versions.
v. 1.117 - Added new operation for calibrate previously aligned images. Now you can carefully align series of images, either via ref points or via auto detecting algorithm, then if needed, correct images aligning across common master image and then calibrate aligned images in pairs, as usual.
See screenshot https://yadi.sk/a/Le5L3bv73VQE3f/5dd3f474e1dfec04e2cd266c and video tutorial https://youtu.be/WvDNM1syRyE
This work only if all operations are maked inside PGMania, because image offsets are stored in inner XML and are used while calibrating.
- The operations menu is rearranged and streamlined to make it easier to navigate align and calibrate operations.

v. 1.116 - Added ability for choosing 3 available modes of working area size for detecting stars - 100%, 50% and 25% from image size. This is usefull for increase detecting speed on large images with great amount of stars.
Look at screenshot here https://yadi.sk/i/OnohBa8_TgIIZQ
- Added simple one touch actions like colors inverting and histogram normalizing.

v. 1.115 - Added wide set of functionality for color processing with choosing transparency, color space, color type, compression and alpha settings.
Added simple one touch actions like colors inverting and histogram normalizing.
Simplified, improved and rewritten algorithms for image calibration with substructing dark and flat images.
Now calibration results can get on the fly when dark and flat images are defined.

v. 1.114 - Added generation and editing of the star mask. Auto-defined stars can add, delete and resize them.
The star mask is generated on the base of the marker layer as a transparent .png file with white circles of stars.
The mask can be used when adding a series of pictures, setting it as a master file. Histogram levels for the mask of stars are adjustable, as well as for all images.
The blending mode of the mask is selected from the list.
This allows frame-by-frame addition to take into account the mask, which can help in eliminating the swelling of stars in the amount.
The mask itself can be generated from any snapshot, for example, from the sum of a series by the median.
Improved algorithms for obtaining images from cameras in the FTP client.
Fixed noticed bugs, improved program interface.

v. 1.113 - Layer with star markers and text labels moved to a separate gif file.
Increased image rendering speed. Added ability to choose algoritm for offsets calculation while aligning - by rectangle contour and by its corners.
The algorithm for automatically searching reference points has been reworked and the visualization of results has been added.
The same visualization is also present when combining images.
The matches found are drawn with lines, which makes evaluation of the result easier and more visual.
The layer with image markers is rendered into separate files stored in the folder with the original images.
This has accelerated the visualization process and allows you to work with markers consistently and independently of the original images.
Marker files contain text, star markers, star statistics, control points, lines, etc., as image files.
Added the choice of the preferred algorithm for calculating offsets.
This calculation is based on contours and angles of quadrilaterals.
The algorithm for calculating offsets by contours is based on the OpenCV algorithm, which describes the outlines of the figure from the matches found.
The algorithm for calculating offsets for control points (the corners of the figure) is copyright.
It works more precisely and faster, and is preferred when aligning to reference points.
The choice of algorithm depends on the source material and preferences.

v. 1.112 - Added functionality of FTP client. This working with images of user FTP servers and (IP) cameras (Web preview, upload to web site and download to local PC). Automatic transfering images from FTP servers and their folders to the local PC folders and to website database. It is possible to register and connect any amount of cameras to watch, transfer and download images. Web service for transfer, publicate and watch (IP) cameras images via web site is optional payent service available by separate request. It is working via prozarium.ru web site only. You can watch and share images from allsky cameras, telescopes, secure, etc.
-Improvements and bugs fixing, as usual.

v. 1.111 - Added functionality to create a color image from separate b/w RGB channels. At input is used three channel R, G and B sums (in any format) and output result is a color image in .tiff. Mechanism is easy to use and convenient. The file of the desired channel is set via the menu in the file list, as the corresponding R, G, or B com ponent, and at screen RGB combibed image is constructed in real time. Histogram settings of the of any channel can be changed at real time and see their resulting effect on the white balance and the final histogram of RGB composition. Alignment of separate channels can be done along the way. Saving the current RGB composition is done by selecting an item in the context menu on the picture, or by selecting the appropriate operation on the "Stack, postprocess" tab. More visual, simple and convenient mechanism simply does not exist.

v. 1.110 - Added ability to apply median filter to aligned source images before stacking them. It significally helps to clear the source files and summ from satellite tracks, cosmic rays, noise, etc. This realised as a separate operation.
