### Install python-gdcm from local source

Source: https://github.com/tfmoraes/python-gdcm/blob/master/README.md

Installs the python-gdcm package after cloning the source code, using pip. This command builds and installs the library from the local repository.

```bash
pip install python-gdcm/
```

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

### Install python-gdcm using pip

Source: https://github.com/tfmoraes/python-gdcm/blob/master/README.md

Installs or upgrades the python-gdcm package from PyPI using pip. This is the recommended method for most users.

```bash
pip install -U python-gdcm
```

### Test GDCM version in Python

Source: https://github.com/tfmoraes/python-gdcm/blob/master/README.md

Tests if the GDCM library is correctly installed and accessible in Python by printing the GDCM version. It also provides a troubleshooting tip for a common import error.

```python
import gdcm
print(gdcm.GDCM_VERSION)
```

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

### Project Build Configuration

Source: https://github.com/tfmoraes/python-gdcm/blob/master/CMakeLists.txt

This CMake script sets up the build environment for the python-gdcm project. It defines project languages, configures build options for applications, documentation, and shared libraries based on the operating system. It also handles finding and configuring Python and OpenSSL dependencies, setting installation paths, and applying platform-specific linker flags for macOS and Linux.

```CMake

### Clone python-gdcm source code

Source: https://github.com/tfmoraes/python-gdcm/blob/master/README.md

Clones the python-gdcm repository from GitHub, including submodules, to build from source. This command fetches the project's source code and its dependencies.

```bash
git clone --recurse-submodules https://github.com/tfmoraes/python-gdcm
```

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

### Set GDCM build environment variables

Source: https://github.com/tfmoraes/python-gdcm/blob/master/README.md

Sets environment variables for CMake and SWIG executables if they are not in the system's PATH. This is necessary when building python-gdcm from source on Linux.

```bash
export CMAKE_EXE="path/to/cmake/executable"
export SWIG_EXE="path/to/swig/executable"
```

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

### Read DICOM image file in Python

Source: https://github.com/tfmoraes/python-gdcm/blob/master/README.md

Demonstrates how to read a DICOM image file using the gdcm.ImageReader class. It checks the return value of the Read() method to confirm successful file parsing.

```python
import gdcm

reader = gdcm.ImageReader()
reader.SetFileName("dicom_image_file.dcm")
ret = reader.Read()

if not ret:
    print("It was not possible to read your DICOM file")
```
