Generate an image with VB.NET

The API takes your HTML/CSS and runs it in an instance of Google Chrome to convert your html into an image. Use VB.NET to send the API your HTML/CSS. You’ll get back the URL to your generated image.

For more details on how this works, see Creating an image.

Example code

This code creates a WebClient, sets credentials and POSTS the HTML & CSS as values to the API. The response will be json with the URL to the generated image.

Imports System.Net
Public Module htciExample

    Sub Main()
        Dim result As Byte()
        Dim html As String = "<div class='ping'>Pong ✅</div>"
            Dim css As String = ".ping {padding: 20px; font-family:'sans-serif'; }"
            Using client = New WebClient
            client.Credentials = New NetworkCredential("user_id", "api_key")
            result = client.UploadValues(
                    "https://hcti.io/v1/image",
                    "POST",
                    New Specialized.NameValueCollection() From {
                                             {"html", html}, {"css", css}
                                             }
                                             )
            End Using
            Dim resultString = System.Text.Encoding.UTF8.GetString(result)
            Console.WriteLine(resultString)
            '{"url":"https://hcti.io/v1/image/9dce5b30-3d9a-46b3-926b-651e5955f9a2"}
    End Sub

End Module
