Dependencies
- Go. This project works with Golang v1.11.1, further Go versions probably should work.
- waifu2x-mac. waifu2x allows to denoise JPEG images and upscale them. This is waifu2x version optimized to run with Metal and macOS. On other operation system you can consider kaifu2x or original waifu2x. https://github.com/imxieyi/waifu2x-mac
- OpenJPEG. This is JPEG2000 library, it allows to save 2x scaled image to file with size near 800kB. macOS supports JPEG2000 by default, on other operation systems you probably should consider alternative file format. http://www.openjpeg.org/.
To intstall it on Mac run
brew install openjpeg
Fetcher usage
Usage of fetcher:
-dir string
where we should save pictures (default "/Users/michael/gopath/src/traipix-best-downloader")
-horiz
allow download horizontal pictures? [-horiz=false], [-horiz=true] (default true)
-pages int
"-pages 10" will take pictures from 10 first pages, if "pages" will be -1 then crawler will take all pages (default 10)
-upscales string
directory where upscaled files stored. With this option you can delete downloaded images keeping only upscales
-vert
allow download vertical pictures? [-vert=false], [-vert=true]
Run go run main.go -pages 10 -dir resultsPath -upscales upscalesPath to download horizontal pictures from 10 first pages to directory resultsPath. Fetcher don't try to download already downloaded or upscaled pictures. -upscales is optional. Also, you can delete downloaded photos after upscalem, fetcher will look to upscaled pictures in this case.
Scaler usage
You should set constants to appropriate in file scaler/main.go for waifu2xmacCmd and
opjCompressCmd.
go run scaler/main.go -i pathToDownloadedPicsDir -o pathToUpscaledPicsDir
This will take pictures from pathToDownloadedPicsDir directory, upscale them to 2x and convert pictures to JPEG2000 format and save it to pathToUpscaledPicsDir directory.
