# AutocadQRCoder
All the magic of AutocadQRCoder comes from the basic use of [QRCoder library](https://github.com/codebude/QRCoder) to create AutoCAD entities (block or hatch) featuring QR Codes.
### Usage
Clone or fork this repository or [download](https://gilecad.azurewebsites.net/Resources/AutocadQRCoder.zip) the assemblies.

In an AutoCAD plugin project, reference the AutocadQRCoder.dll in the folder corresponding to the targeted AutoCAD version (Release\net48 for AutoCAD up to 2024 or Release\net8.0-windows for AutoCAD 2025 and later).

#### Create a Solid background and a Hatch
The caller is responsible to add the newly created hatch and solid entities to a database or dispose them.

Example with default settings:
```c#
var coder = new BlockQRCoder("The text which should be encoded.");
var solid = coder.GetBackgroundSolid();
var hatch = coder.GetHatch();
```

#### Create a block definition
The block definition (BlockTableRecord) is added to the block table of the supplied database. It contains a background Solid and a Hatch representing the QRCode and, optionally, a constant attribute definition with the encoded text.

Example of a block named "QRCode_test" with a dark red hatch and a constant attribute: 
```c#
var coder = new BlockQRCoder("The text which should be encoded.")
{
    ForegroundColor = Autodesk.AutoCAD.Colors.Color.FromRgb(100, 3, 3)
};
ObjectId btrId = coder.CreateBlock(db, "QRCode_test", true);
```

The parameters of the BlockQRCoder constructor are the same as the QRCoder.QRCodeGenerator.CreateQRCode. You can find more informations about these parameters in the [QRCoder wiki](https://github.com/codebude/QRCoder/wiki/How-to-use-QRCoder#3-basic-usage).

## InsertQRCodeBlock
An example of AutoCAD command to insert a QR Code block. A dialog box allows to set encoding parameters and block properties.
