CCD/CMOS imaging server
=======================

Supports FLI cameras/focusers/wheels and cameras: ZWO, Basler, HikRobot, PointGrey, Apogee.
Allows to run as standalone application or imaging server/client.

To restart server (e.g. if hardware was off) kill it with SIGUSR1

## Compile

cmake options:

- `-DAPOGEE=ON` - compile Apogee plugin
- `-DDEBUG=ON` - make with a lot debugging info
- `-DIMAGEVIEW=ON` - compile with image viewer support (only for standalone) (OpenGL!!!)
- `-DBASLER=ON` - compile Basler support plugin
- `-DFLI=ON` - compile FLI support plugin
- `-DFLYCAPT=ON` - compile GrassHopper PointGrey plugin
- `-DHIKROBOT=ON` - compile HikRobot support plugin
- `-DZWO=ON` - compile ZWO support plugin


```

## Image viewer
In image view mode you can display menu by clicking of right mouse key or use shortcuts:

- '0' - restore zoom;
- 'c' - capture new image in pause mode (works only with `-n` flag);
- 'e' - switch on/off histogram equalization;
- 'l' - flip image right-left;
- 'p' - pause or resume capturing (works only with `-n` flag);
- 'u' - flip image up-down;
- 'Z' - zoom+;
- 'z' - zoom-;
- 'Ctrl+r' - roll histogram conversion function (LOG, SQRT, POW, LINEAR);
- 'Ctrl+s' - save displayed image (works only if you pointed output file name or prefix);
- 'Ctrl+q' - exit.

Mouse functions:

- Left button - center selected point.
- Middle button - move image.
- Right button - show menu.
- Wheel up - scroll up, or scroll left (with Shift), or zoom+ (with Ctrl).
- Wheel down - scroll down, or scroll right (with Shift), or zoom- (with Ctrl).
