> Hi,
> While we upload some PDF, we encounter an error like this : "Error: Expected
> operator 'ID' actual='In' at stream offset 142897 []"
>
> We used *2.0.25 pdfbox version* and we also tried *2.0.26* and it will also
> work fine in some pdf, but not with others.

> +Code :+
> public static boolean extractFirstPdfPageAsImageJPEG(final File sourcePdf,
> final File resultImg,
> final Integer maxWidth, final
> Integer maxHeight) {
> try (final PDDocument document =
> PDDocument.load(sourcePdf)) {
> final PDFRenderer pdfRenderer = new
> PDFRenderer(document);
> final BufferedImage extractedImage
> = pdfRenderer.renderImageWithDPI(0, 100, ImageType.RGB);
>
> final int originalHeight =
> extractedImage.getHeight();
> final int originalWidth =
> extractedImage.getWidth();

> int scaledHeight = originalHeight;
> int scaledWidth = originalWidth;
