Create a png image

[saikishore49]

Hi Team,

 i need to create a png/jpg image with incident closed by username and data and time. I need to create a png when incident is closed and attach the png image to the incident record.

Thanks

1. Create a Business Rule: Create a business rule to trigger when an incident is closed. In the business rule, add a script that generates the PNG/JPG image with the required details, such as the username and date/time of incident closure.

2. Save the Image: Save the generated image to a file system or an attachment in the ServiceNow instance.

3. Attach the Image to the Incident Record: Use the ServiceNow Attachment API to attach the image to the incident record. You can use GlideRecord to retrieve the incident record and attach the image using the 'insert()' function

   //Create the PNG/JPG image with the required details
   var image = gs.getImage(500, 100, 'Closed By: ' + current.closed_by.name + ' - ' + current.closed_at);

   //Save the image to the attachment table
   var attachment = new GlideRecord('sys_attachment');
   attachment.initialize();
   attachment.table_name = 'incident';
   attachment.table_sys_id = gr.sys_id;
   attachment.file_name = 'incident_closed.png';
   attachment.file_type = 'image/png';
   attachment.insert();

   //Attach the image to the incident record
   attachment.setValue('content_type', 'image/png');
   attachment.setValue('file_size', image.length);
   attachment.setValue('file', image);
   attachment.update();
   }

Hi Kilo,

Thanks for reply.

when i use below script png image is attached to the record. but when i try to open its not opening it and image size is 0KB.

var image = gs.getImage(500, 100, 'Closed By: ' + current.closed_by.name + ' - ' + current.closed_at);

//Save the image to the attachment table
var attachment = new GlideRecord('sys_attachment');
attachment.initialize();
attachment.table_name = 'incident';
attachment.table_sys_id = gr.sys_id;
attachment.file_name = 'incident_closed.png';
attachment.file_type = 'image/png';
attachment.insert();

//Attach the image to the incident record
attachment.setValue('content_type', 'image/png');
attachment.setValue('file_size', image.length);
attachment.setValue('file', image);
attachment.update();

Check if the current user has the appropriate permissions to capture the screen. You can do this by going to the user's profile record and checking if the "Can capture screen" property is enabled.

Verify that the gs.getImage() function is returning a non-empty image. You can do this by adding some logging statements to your script to print out the length of the image and any error messages that are returned by the function.

Check if the attachment record is being created correctly. You can do this by checking the values of the attachment record in the sys_attachment table after the script has run. Make sure that the table_name, table_sys_id, file_name, and file_type fields are set correctly.

Check if the attachment record is being updated correctly with the image data. You can do this by checking the value of the file field in the sys_attachment table after the script has run. Make sure that the file field contains the correct binary data for the image.

Hi Kilo,

Below is the code with logs

var image = gs.getImage(500, 100, 'This is a png');
gs.log("Image size: " + image.length);

// Save the image to the attachment table
var attachment = new GlideRecord('sys_attachment');
attachment.initialize();
attachment.table_name = 'incident';
attachment.table_sys_id = '8d641046c0a80164000bc7c0d3ed46a0';
attachment.file_name = 'VVVV.png';
attachment.file_type = 'image/png';
attachment.insert();

// Attach the image to the incident record
var grBinaryData = new GlideRecord('sys_attachment_doc');
grBinaryData.initialize();
grBinaryData.parent = attachment.sys_id;
grBinaryData.content_type = 'image/png';
grBinaryData.file_name = 'VVVV.png';
//var imageBytes = new Packages.java.lang.String(image).getBytes("UTF-8");

var imageBytes = new Packages.java.lang.String(image).getBytes("UTF-8");
gs.info("Image size: " + imageBytes.length + " bytes");
grBinaryData.content = imageBytes;
grBinaryData.insert();

*** Script: Image size: undefined
*** Script: Image size: 9 bytes
