# Load a bitmap (BMP) from a byte array in C#

### Image

[Image](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-image.md)

### Bitmap

[Bitmap](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-bitmap.md)

### SVG

[SVG](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-svg.md)

### DICOM

[DICOM](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-dicom.md)

### TIFF

[TIFF](https://www.nutrient.io/guides/dotnet/load-a-file/imaging/from-byte-array-tiff.md)

To load a BMP image from a byte array, use the [`CreateGdPictureImageFromByteArray` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~CreateGdPictureImageFromByteArray.html) of the [`GdPictureImaging` class](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging.html).

This method returns a non-zero GdPicture image identifier (`imageID`) on success. If it fails, it returns `0` — use `GetStat()` to view the failure reason.

Overloads:

- `CreateGdPictureImageFromByteArray(byte[] Data)`

- `CreateGdPictureImageFromByteArray(byte[] Data, DocumentFormat ImageFormat)`

For BMP data, you can explicitly pass `DocumentFormat.DocumentFormatBMP`.

When you no longer need the image resource, release it with the [`ReleaseGdPictureImage` method](https://www.nutrient.io/api/gdpicture/GdPicture.NET.14~GdPicture14.GdPictureImaging~ReleaseGdPictureImage.html).

To load a BMP image from a byte array, use the following code:

### C#

```csharp

using GdPicture14;
using System;
using System.IO;

using GdPictureImaging gdpictureImaging = new GdPictureImaging();

// Create a byte array from a BMP image file.
byte[] byteArray = File.ReadAllBytes(@"C:\temp\source.bmp");

// Create a GdPicture image from the byte array.
int imageID = gdpictureImaging.CreateGdPictureImageFromByteArray(
    byteArray,
    DocumentFormat.DocumentFormatBMP);

if (imageID == 0)
{
    Console.WriteLine($"CreateGdPictureImageFromByteArray failed: {gdpictureImaging.GetStat()}");
    return;
}

GdPictureStatus status = gdpictureImaging.SaveAsPNG(imageID, @"C:\temp\output.png");
if (status!= GdPictureStatus.OK)
{
    Console.WriteLine($"SaveAsPNG failed: {status}");
}

gdpictureImaging.ReleaseGdPictureImage(imageID);

```

### VB.NET

```vb

Imports GdPicture14
Imports System.IO

Using gdpictureImaging As New GdPictureImaging()
    ' Create a byte array from a BMP image file.
    Dim byteArray As Byte() = File.ReadAllBytes("C:\temp\source.bmp")

    ' Create a GdPicture image from the byte array.
    Dim imageID As Integer = gdpictureImaging.CreateGdPictureImageFromByteArray(
        byteArray,
        DocumentFormat.DocumentFormatBMP)

    If imageID = 0 Then
        Console.WriteLine($"CreateGdPictureImageFromByteArray failed: {gdpictureImaging.GetStat()}")
        Return
    End If

    Dim status As GdPictureStatus = gdpictureImaging.SaveAsPNG(imageID, "C:\temp\output.png")
    If status <> GdPictureStatus.OK Then
        Console.WriteLine($"SaveAsPNG failed: {status}")
    End If

    gdpictureImaging.ReleaseGdPictureImage(imageID)
End Using

```
