Answer
It is possible to “Flatten” PDF documents in PrizmDoc Viewer. You can do this by converting the document to a raster format (TIFF is recommended for PDF conversion) using PrizmDoc’s Content Conversion Service, and then converting it back to PDF format. This will result in a PDF with a single layer and no hidden objects. However, this will usually lower the quality and increase the file size of PDFs that are largely text.
Here is an example workflow using the Workfile API and the Content Conversion Service API :
1. Create a WorkFile from PDF
POST {{pccisUrl}}/PCCIS/V1/WorkFile
Content-Type: application/octet-stream
{{file bytes}}
2. Initiate Conversion to TIFF
POST {{pccisUrl}}/v2/contentConverters
Content-Type: application/json
{
"input": {
"sources": [
{
"fileId": "{{fileId}}"
}
],
"dest": {
"format": "tiff"
}
}
}
3. Poll until response[“state”] === “complete”
GET {{pccisUrl}}/v2/contentConverters/{{processId}}
4. Initiate Conversion from TIFF back to PDF
POST {{pccisUrl}}/v2/contentConverters
Content-Type: application/json
{
"input": {
"sources": [
{
"fileId": "{{fileId_from_Step3_output}}"
}
],
"dest": {
"format": "pdf"
}
}
}
5. Poll again
GET {{pccisUrl}}/v2/contentConverters/{{processId}}
6. Download
GET {{pccisUrl}}/PCCIS/V1/WorkFile/{{fileId}}?ContentDispositionFileName={{desiredFileNameWithExtension}}
