David Hoffer commented on PDFBOX-1307:
--------------------------------------
Upon further review, in my case the images were flipped not inverted so I
re-flipped the image after it was created which works for me.
> extracted images from a PDF sometimes come out inverted

> Hi.
> I am extracting images from a PDF (using the code below).
> sometimes the images appear inverted
> PDResources r = page.getResources();
> Map<String, PDXObjectImage> images = r.getImages();
> for (Map.Entry<String, PDXObjectImage> e : images.entrySet()) {
>
> BufferedImage bi = null;
> try {
> bi = ((PDXObjectImage) e.getValue()).getRGBImage();
> } catch (Exception ee) {
> logger.info("can't read image ;-(", ee);
> }
> if (bi != null) {
> currentPage.addImage(bi);
> ((PDXObjectImage)
> e.getValue()).write2file("/tmp/II"+e.getKey());
> }
> }
>
> and i'm not sure, but there may be a memory leak grabbing the images this way
> as well.. but that could in my code.
