## Purpose

This sample program demonstrates how to:

* Apply filter operations on a loaded image.

![](assets/images/sample_programs/image_processing-easyimagefilter.webp)

## Code highlights

1. Load an image file from the disk into an object `EImage`.
   ```c++
   m_SrcImage.Load(ToUtf8(lpszPathName).GetString());
   ```
2. Apply a filter operation on the image.
   ```c++
   EasyImage::ErodeBox(&m_SrcImage, &m_SrcImage, 1);
   EasyImage::OpenBox(&m_SrcImage, &m_SrcImage, 1);
   ...
   ```
