Struct AcroFormDocument 

pub struct AcroFormDocument { /* private fields */ }

High-level wrapper for PDF documents with forms

Implementations

impl AcroFormDocument

pub fn from_pdf<P: AsRef<Path>>(path: P) -> Result<Self, PdfError>

Load a PDF document from a file path

Example

use acroform::AcroFormDocument;

let doc = AcroFormDocument::from_pdf("form.pdf")?;

pub fn fields(&self) -> Vec<FormField>

Get all fillable fields in the document

Returns a list of all terminal fields (fields that can be filled). Parent/container fields are not included.

Example

use acroform::AcroFormDocument;

let doc = AcroFormDocument::from_pdf("form.pdf")?;
for field in doc.fields() {
    println!("Field: {} ({:?})", field.name, field.field_type);
}

pub fn fill_and_save<P: AsRef<Path>>( &mut self, values: HashMap<String, FieldValue>, output: P, ) -> Result<(), PdfError>

Fill form fields and save to a new file

Updates the specified fields with new values and saves the result. Deletes existing appearance streams (/AP) to force PDF viewers to regenerate them. This ensures consistent behavior across different PDF viewers.

Arguments

• values - Map of field names to new values
• output - Output file path

Example

use acroform::{AcroFormDocument, FieldValue};
use std::collections::HashMap;

let mut doc = AcroFormDocument::from_pdf("form.pdf")?;

let mut values = HashMap::new();
values.insert("name".to_string(), FieldValue::Text("John Doe".to_string()));
values.insert("age".to_string(), FieldValue::Integer(30));

doc.fill_and_save(values, "filled.pdf")?;
