Go API

package main

import (
	"context"
	"fmt"
	"os"

	"github.com/huzpsb/pdfcpu2/pkg/api"
	"github.com/huzpsb/pdfcpu2/pkg/pdfcpu/model"
)

func main() {
	ctx := context.Background()
	conf := model.NewDefaultConfiguration()

	f, err := os.Open("in.pdf")
	if err != nil {
		panic(err)
	}
	defer f.Close()

	// nil page selection = all pages; true = include fonts
	info, err := api.PDFInfo(ctx, f, "in.pdf", nil, true, conf)
	if err != nil {
		panic(err)
	}
	fmt.Println("pages:", info.PageCount)
}

Shortcut for just the page count or page dimensions:

n, err := api.PageCountFile(ctx, "in.pdf")       // int
dims, err := api.PageDimsFile(ctx, "in.pdf")     // []types.Dim, one per page
