validate: invalid border array

[ximbal]

I am validating a group of PDF files, I am getting this error:

PDF validation failed for file documents/process/move-rename/pdf-from-zip/684c366a052e42889156a47eee17a9d6d88326e55d8bda2b4851bdad10fdb63e.pdf: validation error (obj#:11): invalid border array: [10 10 10 60]PDF validation failed for file documents/process/move-rename/pdf-from-zip/684c366a052e42889156a47eee17a9d6d88326e55d8bda2b4851bdad10fdb63e.pdf: validation error (obj#:11): invalid border array: [10 10 10 60]Error combining and stamping PDFs: error combining PDF files: invalid border array: [10 10 10 60]
exit status 1

using the following code:

func validatePDFs(pdfFilePaths []string) (string, error) {
	for _, pdfFilePath := range pdfFilePaths {
		if err := api.ValidateFile(pdfFilePath, nil); err != nil {
			fmt.Printf("PDF validation failed for file %s: %v", pdfFilePath, err)
			return pdfFilePath, err
		}
	}
	return "", nil
}

I've been trying to find documentation around it.

Is this a bug?

Thank you.

Hello!

I need to see a stacktrace in order to tell you more.
if you can share the file even better.

Thank you!

This border dict seems to be in violation of the PDF specification:

Thank you for the insight.

It seems that this was created with Crystal Reports, I am only merging in chronological order 200 PDF files. I was aiming to do it with pure golang. I can achieve the merging by using some CLI tools such as pdftk.

I understand that the goal is to stick as much as possible to the PDF specification. But my usecase is not about creating a PDF. but to merge a list of received files of which there are some malformed (such as this one).

Perhaps it would be worth thinking how to deal with this kind of "malformations" specially for merging pdfs.

I do appreciate your help and salute your efforts with PDFCPU.

Regards,

This is fixed in the latest commit by relaxing validation for Border arrays.
