# filmout_display
|
||||
|
||||
This repo contains the source code for the `filmout_display` binary that displays images on a screen for the purposes of creating analog moving images from digital sources.
|
||||
This application will take over the full screen when launched and display frames as instructed with JSON objects sent over a TCP socket.
|
||||
|
||||
## Features
|
||||
|
||||
* Display image full screen, maintaining aspect ratio of original
|
||||
* Display image scaled for different capture requirements and stocks
|
||||
* Display image for specified length of time in milliseconds
|
||||
* Display image until instructed to stop
|
||||
|
||||
## Future Goals
|
||||
|
||||
* Display image one channel at a time (RGB) for specified lengths of time for color balancing to different stocks
|
||||
* Display image inverted for print stocks
|
||||
* Convert images from color to black and white with different profiles
|
||||
|
||||
## Dependencies
|
||||
|
||||
* [OpenGL](https://www.khronos.org/opengl/)
|
||||
* [OpenCV](https://github.com/opencv/opencv)
|
||||
* [nlohmann/json](https://github.com/nlohmann/json)

# Usage from an external project:

# In your CMakeLists.txt, add these lines:

# FIND_PACKAGE(OpenCV REQUIRED)
|

# TARGET_LINK_LIBRARIES(MY_TARGET_NAME ${OpenCV_LIBS})

# FIND_PACKAGE(OpenCV REQUIRED core imgcodecs)

# If the module is found then OPENCV_<MODULE>_FOUND is set to TRUE.

# - OpenCV_COMPUTE_CAPABILITIES : The version of compute capability
