PGMania brief description
/pterodactilus vulgaris/

The main program features in brief

Preview images

PGMania can be used as a image viewer and source images filter tool. It shows images or first frame of movie in preview, zoom or fit image, allows to navigate thru image list, filter it and delete images.

Building sequences of images

The program helps to rebuild sequence of image files and restore continuous order of files after they were edited, deleted, renamed or moved.
PGMania constructs movies from sequence of numbered images. She constructs image sequence based on selected type and file name template. Once the image sequence been set, PGMania builds movie from image sequence and can be used to concatenate several movies into one.

Creating video

PGMania can filter the source images and build movie with them. Also it is possible to build one movie from several parts by concatenating separate parts. It creates 16-bit AVI gray/color video files from images series, concatenates video files together into one video file.

By default PGMania builds 16bpp gray movies and use ffv1 lossless codec when you make movie.
If you want to change the default codec used, then you need to edit codec name in parameters window to use it with your images when building movie.
You can change the codec name manually in parameters window to another one by typing it. You can make Raw video movie from image sequence too.
With Raw video the codec will be set by ffmpeg automatically, based on type of source images.
By default the PGMania's uses AVI container for movies but you also can change it to desired one (.mov, etc.).
The PGMania translates your parameters into internal FFMpeg commands, so changing the parameters and templates may help to achieve the desired results.
Used codecs by default: ffv1, rawvideo

Image conversion

PGMania can convert image files from one format to another. Supports batch converting operations for image sequences. Image formats can be any of well known image formats. The program reads and displays the most famous image formats.

It converts images and series of images, align and fit them with each other by defining a master image and calibrate a pair of images with the same subject.

Detecting stars

Program detects stars on the images and store in xml files operations history and detected stars statistics.

Screen modes

Supports 5 display modes, including fit to window mode, fit to width, 100%, and 3x Zoom. Also available "fit to screen" or "crop" mode to speed up align process.

Separately, it should be noted rich functionality for handling captured series of images.
Full cycle of manual/auto aligning and calibration deep sky images processing. The program can convert images, align them with each other on master frame base and calibrate a pair of images with the same subject.

Aligning images

The program uses its own image combining algorithms and for some tasks the functions of the OpenCV library. Search and calculation of offset, and the subsequent combination of images is performed in several ways:
1. automatic determination of stars, search for matches on them in the pictures and the calculation of offsets
2. Setting reference points, automatically searching for the same points on other images and calculating offsets
Offsets are calculated in 3 ways:
1. calculation of offsets and angle of rotation of images through the OpenCV functions
2. own algorithms for calculating coincident figures and displacements between them
3. proprietary algorithms for calculating offsets by control points

Images calibration

When calibrating here is used an new algorithm for processing the pair of images with coinciding signal and with a difference of a noise. As a result we have to completely remove hot pixels, garbage and random noises from both calibrating images of a pair.
This drastically increases the signal / noise ratio. Pictures calibrated by this technology does not require additional processing and are immediately ready for stacking. For more info see Help (now in Russian only).
PGMania uses original algorithms for image calibration. All you need is two images with star fields (lights). No need for dark & bias files for calibration and fit images.

At the same time, the program can use specially prepared dark and flat files for a more complete and comprehensive cleaning of lights from random noise, satellite tracks, cosmic rays, optics, etc. All necessary tools for this implemented in full range.

Color processing

The primary purpose of PGMania is operate with 16bpp gray image format (.pgm, etc). But it works well with many of known 8/16 bpp image formats.
Also PGMania can convert image files from one format to another. She supports batch converting operations for image sequence.
Image formats can be any of well known image formats. PGMania does not aims to operate with color as a whole. But in theory the PGMania can support any image formats thru ImageMagick and FFMpeg which it uses.

PGMania can create RGB and LRGB color images from monochrome images. The color balance adjustment is made by adjusting the image levels of individual channels in highlights and shadows, and the channel alignment is done simultaneously. This greatly simplifies the process of mixing and achieving an optimal resultant color image.

Monitoring and downloading camera images

We have announce two different types of work with your FTP server and IP cameras images.
1. Obtaining images from the camera, sending them to the FTP server. You need to register your FTP server and IP camera (you should already have credentials for this) and your IP camera should already send images to this FTP server. These images will be downloaded to your local computer in the specified date range. You can configure work with several cameras at the same time.
2. Web based transferring images service. You can register transferring your IP camera images to our Web UI on Prozarium.ru
You will be able to view images from an IP camera over the Internet and download them in full size.
This service works automatically and you will receive all the images for the period (24 hours by default) from your FTP server with the rotation of images in the selected album on a site. It is optional service and you should pay for it separately.


PGMania was tested on Win 7/8/10 (32/64).

Tested image types: .pgm, .fit/.fits, .tif, .png, .bmp, .jpg, .gif, etc.
Supporting video: .avi, .mov, .mpeg, .mjpeg, .mp4, etc.
