Have a field to inform the OCR DPI

When working with PDF data extraction, using OCR, the default DPI value of the "Get PDF Region Text" command is 110, leaving the image very small, reducing the accuracy of the result. Having a field where I can easily change this number and have IBM RPA recalculate the region on top of this value, we will have better accuracy in extracting data from the PDF.

defVar --name pdf --type Pdf
defVar --name _region --type Rectangle --parameter  --output
defVar --name _points --type List --innertype String
defVar --name _point --type Numeric
defVar --name _text --type String
defVar --name _newRegion --type String
defVar --name _page --type Numeric
defVar --name success --type Boolean
pdfOpen --file "C:\\Users\\003925631\\Desktop\\PDF\\CLC001520_INVOICE_ORIGINAL_107102.pdf" success=success pdf=value

setVar --name "${_region}" --value "470,318,53,12"
