Image used in column are not displayed in pdf

Hello Team, I have used images in grid by using custom cell template. While doing pdf export its only showing colname value rather then cell template display value. I found internally $parse(row.getEntityQualifiedColField(col) is used to fetch column data in getCellValue function which again using column.field value. I think its not correct.

Can you please help me on this issue? How to get column whole value including image and text all?
