# desqueeze
desqueeze produce the de-squeezed(stretched) image file. desqueeze is written in Go, install is deadly simple - just grab the binary from [Releases page](https://github.com/etsxxx/desqueeze/releases) and drop it in your `$PATH`.
## I/O Example
input (before de-squeeze)
output (after de-squeeze)
# Installation
## from Releases
Go to the [Releases page](https://github.com/etsxxx/desqueeze/releases) and download the file. Unpack the archive file, and put the binary to `$PATH` or somewhere you want.
# Usage
## Basics
### Simply
Run the binary with image file path.
```
desqueeze [OPTIONS] imagefile
```
desqueeze produce the de-squeezed(stretched) image file.
The filename is input filename with suffix '-desqueeze'. (ex: input.jpg -> input-desqueeze.jpg)
### Change multiplies
desqueeze default multiplies width by 1.33. If the squeeze factor of your lens is x2.00, run with `-m 2.00` option.
```
desqueeze -m 2.00 imagefile
```
### Overwrite mode
With batch or photo management software (ex: Adobe Lightroom Classic), `--overwrite` option is worth using. **This option overwrites input file.**
```
desqueeze --overwrite imagefile
```
## Options
You can see all `[OPTIONS]` with `--help` command.
### -h, --help
Display a help message.
### --version
Display the version.
### --out value, -o value
Specify the output file path. The default value is input file path with suffix '-desqueeze' (ex: input.jpg -> input-desqueeze.jpg)
### --multiply value, -m value
Multiplies the image width by the specified number. The default is `1.33`. If your anamorphic lens is x2.00, set `-m 2.00`.
### --quality value, -q value
Specify the output JPEG file quality. The default is `100`.
### --overwrite, -O
desqueeze does not create new file, overwrite input file.
**Be careful not to run on the original file.**
# Hack and Develop
First, fork this repo, and get your clone locally.
1. Install [go](http://golang.org)
2. Install `make`
3. For cross build, install [goxc](https://github.com/laher/goxc)
To test, run
```
make test
```
To build, run
```
make build
```
This will create a `desqueeze` binary in `.bin/`.
To cross build, run
```
make cross
```
This will create the Linux/MacOS/Windows packages in the `./dist/snapshot/` directory.
**PRs are welcome!**
