Alteracoes na versao 3.3.0

Integracao de DCRAW versao 8.95 revista 1.425

Problemas corrigidos:
Discricao do ficheiro HTML nao era criado quando se fazia a integracao em série.Resolvido.

O modo de calibracao da tela do fundo, nao foi escrita na discricao HTML do ficheiro. Resolvido.
DSS Live: Mostrava incorrectamente 16 bits na lista de ficheiros omitindo a verdadeira profundidade do ficheiro (isto nao interferia com o processo). Resolvido.
DSS Live: Ligacao de copia para o clipboard nao estava disponivel na Aba Integracao de Imagem. Resolvido.

Portrait mode RAW pictures were not correctly decoded in all the modes. Fixed.
Now, all the pictures are decoded in landscape mode regardless of the picture settings.

Changes in version 2.0.9
Add 2 stacking methods:
- Auto adaptive weighted average
- Entropy weighted average (High Dynamic Range). This is a first version.

Use of RAW files even while using bilinear interpolation. The bilinear interpolation is now computed after the subtraction of the masters flat and offset/bias and after the application of the master flat.

The memory usage is divided by 3, and some processes time is also divided by 3: computing of masters, subtraction of master offset and dark, calibration and application of master flat.

Integration of DCRAW release 1.330.

Bug Fixes:
When using median, and kappa-sigma stacking method, the red channel was replaced by the blue channel. Fixed.
Crash when creating multiples master flat frames. Fixed.
Incorrect checking when using multiples already created master frames (Dark, Flat and Offset/Bias). Fixed.
Loss of precision when using 32 bits TIFF bitmaps for another stacking process. Fixed.

The User's Manual and Technical details are updated.


Changes in version 2.0.8
Add median, maximum and kappa-sigma stacking (on top of average stacking which is still available).
You can use either method when creating masters (dark, flat and offset/bias) and stacking light frames.
Add selection of the working folder that is containing the temporary files created during the stacking process.

A new dialog is used to configure the method for each type of frame and to change the working folder.


Add full detection of stars (no need to specify a threshold anymore).
Note: it is recommended to register the pictures again to benefit from this evolution

The matching algorithm has been partially rewritten for a better matching and to allow small non linear distortions between pictures.

Optimization of the drive space needed to create median picture from dark, flat and offset frames.
In most cases half the space is needed compared to previous versions of DeepSkyStacker.

Add the possibility to copy the list content to the clipboard. This feature is available from the list context menu (mouse right button).

Enhancement of the visualization when zooming pictures (no more interpolation mode when drawing pictures).
Performance enhancement: the decoding of raw pictures is now 4 to 5 times faster.

Integration of DCRAW release 1.328.

The User's Manual, FAQ and Technical details are updated.

Bug Fixes:
The total time of the resulting picture was not computed. Fixed.
Crash when trying to stack only one picture (I know it's silly but it's fixed nevertheless).
Incorrect view when a smaller picture was opened in the processing tab before a stacking process. Fixed.
Slightly incorrect median picture when an odd number of pictures was used. Fixed.
Incorrect estimation of the necessary disk space needed when using offset/bias frames. Fixed.
A Master (Dark, Flat of Offset/Bias) created with 3 channels could not be directly used again with CFA pictures. Fixed.


Changes in version 2.0 Beta 7
Add stacking with different ISO speeds and exposure times.
The dark, flat and offset/bias frames applied to the light frames are automatically selected using the ISO speed and exposure time of each picture.
Just before starting a new registering or stacking process a screen summarizes the processes that will take place.

Multiple selection of files in the picture list
Context menu on the picture list:
- to change file type (light, dark, flat, offset/bias)
- to check/uncheck one or more files
- to remove files from the list
- to view and edit the file properties including ISO speed and exposure time

Add ISO and exposure time columns in the picture list.
The column order of the picture list may be changed. The column order is kept from one session to the next.

Automatic use of ISO speed and exposure time contained in RAW and some TIFF files when computing the total exposure time.

Performance enhancement: the stacking process is now between 30 and 40% faster.

The User's Manual, and FAQ are updated.


Changes in version 2.0 Beta 6
Read/Write TIFF 32 bit/channel (rational) files.
These files can be read and written by Photoshop CS2.
Support of PNG files (8 bit/channel only).
