🖼️ Image Resizer Tool

A robust Command Line Interface (CLI) tool built with C# .NET 10 to automate batch image resizing. This project uses ImageSharp for efficient, cross-platform image processing.

🚀 Features

• Proportional Resizing: Define the target height, and the width is automatically calculated to maintain the original aspect ratio.
• Automatic Organization:
  • Monitors a specific Input folder.
  • Moves original files to a Finished folder.
  • Saves processed images to a Resized folder.
• Smart Naming: Adds a unique timestamp to processed files to prevent overwriting.
• Cross-Platform: Runs natively on Windows and Linux (including single-file executable support).

🛠️ Tech Stack

• .NET 10
• SixLabors.ImageSharp

📂 Folder Structure

Upon execution, the tool automatically creates the following directory structure:

/ (Executable Root)
│
├── Input_Files/         <-- Drop your original images here
├── Resized_Files/       <-- Resized images will appear here
└── Finished_Files/      <-- Original images are moved here after processing

⚙️ How to Run (Development)

1. Clone the repository:

   git clone https://github.com/SavioDec/Image_Resizer.git
   cd Image_Resizer
   

2. Restore dependencies:

   dotnet restore
   

3. Run the application:

   dotnet run
   

📦 How to Build (Create Executable)

Use the following commands to generate a single, self-contained executable (no .NET installation required on the target machine).

🐧 For Linux (x64)

Generates a single binary file with native dependencies included.

dotnet publish -c Release -r linux-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true -p:DebugType=None

Output location: bin/Release/net10.0/linux-x64/publish/

🪟 For Windows (x64)

Generates a single .exe file.

dotnet publish -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:DebugType=None

Output location: bin/Release/net10.0/win-x64/publish/

📝 Usage Example

1. Run the executable.
2. The program asks: Enter the desired new height:
3. You type: 200 (and press Enter).
4. Drop an image (e.g., photo.jpg) into the Input_Files folder.
5. The tool automatically:
   • Creates a resized version (e.g., photo_20260118_143000.jpg) in Resized_Files.
   • Moves the original photo.jpg to Finished_Files.
