How to get the page size for a Word doc?

[sagar-kalburgi-ripcord]

Description

demo.docx

I want to be able to get the page size of a word doc using Unidoc.

Expected Behavior

This code is supposed to print the page size of the document.

doc, err := document.OpenTemplate("demo.docx")
if err != nil {
log.Fatalf("error opening document template: %s", err)
}

fmt.Println("Size: ", doc.BodySection().X().PgSz)

Note: Please find the demo.docx attached.

Actual Behavior

The code above returns nil for page size. In fact, it returns a nil for each and every field in the struct https://apidocs.unidoc.io/unioffice/v1.21.0/github.com/unidoc/unioffice/schema/soo/wml/#CT_SectPr

Hi @sagar-kalburgi-ripcord,

You need to use function document.Open instead the document.OpenTemplate, as the document.OpenTemplate will maintain the styles that being used.

Thanks for the clarification! I'll try this out and respond

Hi @sampila

Thanks, your suggestion worked. I have a question, so this program works

doc, err := document.OpenTemplate("demo.docx")
if err != nil {
log.Fatalf("error opening document template: %s", err)
}

fmt.Println("Size: ", doc.BodySection().X().PgSz)

And the output it prints is

Size: &{12240 15840 <nil>}

I suppose 12240 is the width of any page of the document in twips and 15840 is the height of any page in the document in twips?

But if I try to print doc.BodySection().X().PgSz.WAttr.ST_UnsignedDecimalNumber it prints a hexadecimal number 0x140002f68f0. How is this value related to 12240?

Hi @sagar-kalburgi-ripcord,

the when you are print the doc.BodySection().X().PgSz.WAttr.ST_UnsignedDecimalNumber and it is showing hexadecimal number, that's actually the address value, as it is pointer, to print the integer value, you can use

if pgSize := doc.BodySection().X().PgSz; pgSize != nil {
    if pgSize.WAttr != nil && pgSize.WAttr.ST_UnsignedDecimalNumber != nil {
        fmt.Println("Size: ", *pgSize.WAttr.ST_UnsignedDecimalNumber)
    }
}
