### Join Paths with Platform Separators (Python)

Source: https://developers.scan2cad.com/python/index

The `s2c.join` class simplifies path construction by using the appropriate path separator for the current operating system. It takes a base path and any number of additional path components as arguments.

```python
import s2c

# Join paths using platform-specific separators
full_path = s2c.join('/home/user', 'data', 'images', 'file.png')
# On Windows, this might be 'C:\Users\user\data\images\file.png'
# On Linux, this might be '/home/user/data/images/file.png'

```

### Convert PDFs to DXF Files (Python)

Source: https://developers.scan2cad.com/python/index

The `s2c.PDFsInDirToDxfs` class is designed to extract vector data from all PDF files located in a specified input directory and save them as DXF files in an output directory. This is a core utility for batch conversion tasks.

```python
import s2c

# Convert all PDFs in 'input_pdfs' to DXF in 'output_dxf'
s2c.PDFsInDirToDxfs('/path/to/input_pdfs', '/path/to/output_dxf')

```

### List Files in Directory (Python)

Source: https://developers.scan2cad.com/python/index

The `s2c.list` class allows you to list files within a specified directory. It can filter files by a given extension, which can be a single string or a list of strings. This is useful for processing specific file types within a folder.

```python
import s2c

# List all files in a directory
files = s2c.list('/path/to/directory')

# List only PDF files
pdf_files = s2c.list('/path/to/directory', extension='.pdf')

# List multiple file types
image_files = s2c.list('/path/to/directory', extension=['.png', '.jpg', '.tiff'])

```

### Vectorize Images in a Directory using Scan2CAD

Source: https://developers.scan2cad.com/python/index

This code snippet shows how to vectorize all PNG images found in a given directory using the Scan2CAD Python API. It opens each image, applies vectorization using a default preset, and saves the resulting vector image. This function requires the 's2c' library.

```python
import scan2cad as s2c

in_dir = "path/to/input_directory"
preset = s2c.Preset() # Uses default vectorization settings

imgs = s2c.list(in_dir, "png") # Lists all PNG files in the directory
for i in imgs:
    r = i.open() # Opens the raster image
    v = r.vectorize(preset) # Vectorizes the image
    v.save(r.path) # Saves the vectorized image to the original path

```

### Extract Raster Images from PDF using Scan2CAD

Source: https://developers.scan2cad.com/python/index

This snippet demonstrates how to extract all raster images from PDF files within a specified directory using the Scan2CAD Python API. It iterates through PDF files, opens them, and saves any extracted raster images to the same directory. Dependencies include the 's2c' library.

```python
import scan2cad as s2c

in_dir = "path/to/input_directory"

pdfs = s2c.list(in_dir, "pdf")
for p in pdfs:
    pp = p.open() # Opens the PDF file
    # Saves extracted raster images to the input directory
    pp.save(s2c.FileType.RASTER, s2c.join(in_dir, p.get_name()))

```
