### Install lz4 on reMarkable Tablet

Source: https://context7.com/cloudsftp/resnap/llms.txt

Installs the lz4 compression binary on the reMarkable tablet to improve transfer performance. This involves copying a pre-compiled static binary and making it executable.

```bash
# Check your local lz4 version first
lz4 --version

# Copy matching version to reMarkable (version 1.9.2 or 1.10.0)
scp bin/lz4-1.10.0.arm.static root@10.11.99.1:/opt/bin/lz4
ssh root@10.11.99.1 'chmod +x /opt/bin/lz4'

# Alternative location (legacy)
scp bin/lz4-1.9.2.arm.static root@10.11.99.1:/home/root/lz4
ssh root@10.11.99.1 'chmod +x /home/root/lz4'
```

This snippet demonstrates how to copy a pre-compiled `lz4` binary to the reMarkable tablet via SCP and then make it executable using SSH. This is recommended for improving reSnap performance.

```bash
scp bin/lz4-<version>.arm.static root@$REMARKABLE_IP:/home/root/lz4
ssh root@$REMARKABLE_IP 'chmod +x /home/root/lz4'
```

### Basic Screenshot Capture with reSnap

Source: https://context7.com/cloudsftp/resnap/llms.txt

Captures a screenshot from a reMarkable tablet using the default IP address and displays it using feh. A temporary file is created for the snapshot.

```bash
# Basic usage - captures and displays screenshot
./reSnap.sh

# Expected output: Opens feh displaying the captured screenshot
# Temporary file created at /tmp/reSnap/snapshot_YYYY-MM-DD_HH-MM-SS.png
```

--------------------------------

### Run reSnap Script

Source: https://github.com/cloudsftp/resnap/blob/latest/README.md

This command executes the main reSnap script to capture a screenshot from the reMarkable tablet. It assumes the script is in the current directory and SSH access is configured.

```bash
./reSnap.sh
```

--------------------------------

### Connect to reMarkable via Custom IP Address

Source: https://context7.com/cloudsftp/resnap/llms.txt

Connects to a reMarkable tablet over WiFi using a specified IP address. This can be done directly via a command-line argument or by setting the REMARKABLE_IP environment variable.

```bash
# Connect via WiFi with custom IP
./reSnap.sh -s 192.168.1.100

# Using environment variable
export REMARKABLE_IP=192.168.1.100
./reSnap.sh

# Expected output: Screenshot captured from device at specified IP
```

--------------------------------

### Create Transparent Sketches with reSnap

Source: https://context7.com/cloudsftp/resnap/llms.txt

Removes the white background from the screenshot and resizes it for sketch extraction using ImageMagick. This can be used to create transparent PNGs for sketch mode.

```bash
# Create transparent sketch
./reSnap.sh -f -o sketch.png

# Sketch mode with clipboard
./reSnap.sh -f -x
```

--------------------------------

### Copy reSnap Screenshots to Clipboard

Source: https://context7.com/cloudsftp/resnap/llms.txt

Copies the captured screenshot directly to the system clipboard using xclip. This can be combined with saving to a file or disabling the display.

```bash
# Copy to clipboard
./reSnap.sh -x

# Copy to clipboard and save to file
./reSnap.sh -x -o backup.png

# Copy to clipboard without display
./reSnap.sh -x -n
```

--------------------------------

### Configure reSnap Color and Pixel Formats

Source: https://context7.com/cloudsftp/resnap/llms.txt

Adjusts color correction and pixel format handling for reMarkable 2 devices with different firmware versions. Options include disabling color correction for newer firmware and byte correction for older firmware.

```bash
# Disable color correction (enables highlighter colors on firmware 3.24+)
./reSnap.sh -c

# Disable byte correction for firmware < 3.6
./reSnap.sh -p

# Both corrections disabled
./reSnap.sh -c -p

# Using environment variables
export RESNAP_COLOR_CORRECTION=false
export RESNAP_BYTE_CORRECTION=false
./reSnap.sh
```

--------------------------------

### Capture reSnap Screenshots in Landscape Orientation

Source: https://context7.com/cloudsftp/resnap/llms.txt

Captures the screenshot in landscape orientation by applying a 90-degree rotation transform. This can be used independently or combined with saving to a file.

```bash
# Capture in landscape mode
./reSnap.sh -l

# Combine with output file
./reSnap.sh -l -o landscape_screenshot.png
```

--------------------------------

### Control reSnap Screenshot Display and Saving

Source: https://context7.com/cloudsftp/resnap/llms.txt

Manages whether the screenshot is displayed after capture using feh or only saved to a file. This can be controlled via command-line flags or the RESNAP_DISPLAY environment variable.

```bash
# Force display the snapshot
./reSnap.sh -d

# Capture without displaying (save only)
./reSnap.sh -n -o screenshot.png

# Using environment variable for default behavior
export RESNAP_DISPLAY=false
./reSnap.sh -o silent_capture.png
```

--------------------------------

### Save reSnap Screenshots to a Specific File

Source: https://context7.com/cloudsftp/resnap/llms.txt

Saves the captured screenshot to a user-defined file path instead of a temporary location. This option can also be combined with landscape orientation.

```bash
# Save to specific file
./reSnap.sh -o ~/screenshots/remarkable_capture.png

# Save with landscape orientation
./reSnap.sh -o ~/screenshots/landscape.png -l

# Expected output: File saved to specified path
# File: ~/screenshots/remarkable_capture.png
```

--------------------------------

### Invert Colors in reSnap Screenshots

Source: https://context7.com/cloudsftp/resnap/llms.txt

Inverts the colors of the captured screenshot, which is useful for dark mode viewing or specific image processing needs. This can be controlled via a command-line flag or an environment variable.

```bash
# Invert colors
./reSnap.sh -i

# Using environment variable
export REMARKABLE_INVERT_COLORS=true
./reSnap.sh

# Combine with other options
./reSnap.sh -i -l -o inverted_landscape.png
```
