Pega Robotic Studio: How to convert OpenSpan.Adapters.Web.Controls.Image object into System.Drawing.Image object
I am trying to implement OCR concept by using OneNote in Pega Robotic studio. Which i did. I am trying to read all images in a web page then trying to read text from it.
Here i stuck it gives me OpenSpan.Adapters.Web.Controls.ImageCollection proxy then OpenSpan.Adapters.Web.Controls.Image Image proxy. This image proxy doesnt have a method to save it local and not accepting in my script.

Dear Sasnt,
Thanks for your reply. I have done extracting text from image by using Microsoft.office.interop.onenote.dll in a script.
In the script i have used methods like createnewpage() , getcontents() of Microsoft one note dll.
I have completed extracting text from image that is ocr concept by choosing an image saved in local machine.
Now Assuming that i want to extract text from image which is in web page. I use Images property of webpage to get the collection of images. From that i can loop through each image. In order to use the image in my script either i need to save it first then converting into byte[].
My question is openspan image control doesn't have save method , is there any way to use the image in picturebox or converting that image to byte[]..
Images property how can i exactly use it if i want to see the image ???
Please refer this article which contains my script
I understand now. Your script requires images from a web page to be saved to disk. I don't know of a native method for doing this specifically with Pega Robotics out-of-the-box methods. I suspect you will need to write some C# code since JavaScript will not give you direct access to the file system. Assuming you can trigger a save dialog via JavaScript though, you might be able to interrogate those controls and automate it that way.
Accepted Solution
Kindly refer below code used for to download images from a web page.
In order to achieve downloading images from websites please follow below steps.
1. Add a window form and a web browser control to it.
2. Create a constructor of WebClient class.
3. By using Byte[] value images are downloaded of the type of System.Drawing.Imaging.
refer below screenshot to achieve the same.
Script to download from Byte[] input
using System.Drawing.Imaging;
Parameters : string filenamepng,string filenamejpeg, byte[] data
using (MemoryStream mem = new MemoryStream(data))
{
using (var yourImage = Image.FromStream(mem))
{
// If you want it as Png
yourImage.Save(filenamepng, ImageFormat.Png) ;
// If you want it as Jpeg
//yourImage.Save(filenamejpeg, ImageFormat.Jpeg) ;
}
}
I am not sure what you are asking. Since I don't know what your script does, I cannot suggest how to use it. The OpenSpan.Adapters.Web.Controls.Image does not have a Save method, so you cannot use that object natively to save it.
