## Description

A rect holds four coordinates for a rectangle.

The coordinates for a rectangle include left, top, right, bottom. Width () and height () defines the rectangle's width and height. LLx and LLy defines lower left corner, and URx and URy defines the upper right corner.

## Constructors

### Rect

```csharp
Datalogics.PDFL.Rect.Rect()
```

*constructor*

Create a rectangle with all values zero.

### Rect

```csharp
Datalogics.PDFL.Rect.Rect(double nLLx, double nLLy, double nURx, double nURy)
```

*constructor*

**Parameters**

- `nLLx` (`double`): the X coordinate of the lower left corner of the rectangle
- `nLLy` (`double`): the Y coordinate of the lower left corner of the rectangle
- `nURx` (`double`): the X coordinate of the upper right corner of the rectangle
- `nURy` (`double`): the Y coordinate of the upper right corner of the rectangle

Create a Rect.

### Rect

```csharp
Datalogics.PDFL.Rect.Rect(System.Drawing.Rectangle r)
```

*constructor*

**Parameters**

- `r` (`System.Drawing.Rectangle`): The rectangle to convert

Construct a Rect from a System.Drawing.Rectangle

Note that the coordinate systems are inverted for PDFL. Smaller X/Y values are assigned to the lower left coordinate.

### Rect

```csharp
Datalogics.PDFL.Rect.Rect(System.Drawing.RectangleF r)
```

*constructor*

**Parameters**

- `r` (`System.Drawing.RectangleF`): The rectangle to convert

Construct a Rect from a System.Drawing.RectangleF

Note that the coordinate systems are inverted for PDFL. Smaller X/Y values are assigned to the lower left coordinate.

## Properties

### Bottom

```csharp
double Datalogics.PDFL.Rect.Bottom { get; set; }
```

the Y coordinate of the lower left corner of the rectangle

### Height

```csharp
double Datalogics.PDFL.Rect.Height { get; }
```

The height of the Rect.

### LLx

```csharp
double Datalogics.PDFL.Rect.LLx { get; set; }
```

the X coordinate of the lower left corner of the rectangle

### LLy

```csharp
double Datalogics.PDFL.Rect.LLy { get; set; }
```

the Y coordinate of the lower left corner of the rectangle

### Left

```csharp
double Datalogics.PDFL.Rect.Left { get; set; }
```

the X coordinate of the lower left corner of the rectangle

### Right

```csharp
double Datalogics.PDFL.Rect.Right { get; set; }
```

the X coordinate of the upper right corner of the rectangle

### RoundedHeight

```csharp
int Datalogics.PDFL.Rect.RoundedHeight { get; }
```

Calculates and rounds the rectangle's height as APDFL does during page rendering.

The width and height rounding algorithms are different inside APDFL, so in DLE they are different as well.

### RoundedWidth

```csharp
int Datalogics.PDFL.Rect.RoundedWidth { get; }
```

Calculates and rounds the rectangle's width as APDFL does during page rendering.

The width and height rounding algorithms are different inside APDFL, so in DLE they are different as well.

### Top

```csharp
double Datalogics.PDFL.Rect.Top { get; set; }
```

the Y coordinate of the upper right corner of the rectangle

### URx

```csharp
double Datalogics.PDFL.Rect.URx { get; set; }
```

the X coordinate of the upper right corner of the rectangle

### URy

```csharp
double Datalogics.PDFL.Rect.URy { get; set; }
```

the Y coordinate of the upper right corner of the rectangle

### Width

```csharp
double Datalogics.PDFL.Rect.Width { get; }
```

The width of the Rect.
