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

• -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

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).
