screentool

=====

A tool to make screenshots in a blazingly fast way (with annotations support).

# Compilation

1. Install required libraries

```bash

apt-get install libgtk-3-dev

```

2. Build the tool

```bash

make

```

Above command will also download and compile dependencies. It may take long time due to gotk3 build process.

Run with `./screentool`.

# Demo

# Basic usage

Use your favorite hotkey to start screentool

1. Select screenshot area

- Select a range by dragging mouse over area of interest - to make a screenshot of a range \

  OR

- Click a window - to make screenshot of a window \

  OR

- Click desktop or the edge of the screen - to make screenshot of the whole desktop

2. Release mouse button. Your screenshot is now saved to your clipboard.

   You can paste it somewhere, e.g. into Gimp, Hangouts or a Skype conversation.

## Advanced usage

### Annotations

Select screenshot range with one of above ways, press and hold `Shift` key and release `Left Mouse Button`.

The tool will enter Annotation mode.

In Annotation mode, current tool can be changed with `Space`.

The following tools are implemented:

- Arrow - drag mouse to create an arrow

- Freehand - drag mouse to create a freehand line

- Line - draw mouse to create a horizontal or vertical line

- Eraser - drag mouse to create a filled rectangle

Release `Shift` to save the screenshot to the clipboard.

Use `Right Mouse Button` to undo last action (creating an annotation or selecting screenshot area).

### Freezing screen

Add `--freeze` parameter to take capture of the whole screen right after starting the tool,

still allowing you to select region or window of interest.

## Saving screenshot

In addition to saving the screenshot to the clipboard, screentool will also save each captured 

screenshot in `$HOME/screenshots` directory if such directory is present in the filesystem.

### Known limitations

Due to the nature of Go static linking, Go apps grow quickly in size.

As a result, if screentool is dropped out of filesystem cache, a noticeable lag may 

occur when starting the tool.
