QUESTION

Reading byte by byte HEIF/HEIC images XMP metadata

Asked 2022-Mar-24 at 08:47

I am trying to build a native byte parser that given an HEIF image it returns back its metadata (mainly width and height of the image). I am struggling a lot at the moment finding the right documentation and specs to use for parsing such info. I have to do such thing for both XMP and EXIF metadata, but let's focus only on XMP for now.

What I need is the exact byte structure of where to find what. According to the HEIF international standard doc (here):

For image items, XMP metadata shall be stored as an item of item_type value 'mime' and content type'application/rdf+xml'. The body of the item shall be a valid XMP document, in XML form.

Perfect, if I analyse a sample image I can find such marker:

From now on I can't find anywhere how to get the info I need. I would expect something saying "the first 2 bytes are the header, with marker 0xFF 0xCE (just an example), the next 2 bytes are the width, and following 2 bytes the height...etc". In my case I am going by intuition. My sample image is of dimensions 8736x5856. If in the tool I look for Big-Endian 2 byte integer 8736, I can find it:

And hey, 2 bytes later there is the 5856 height as well:

But again, I arrived here by luck and intuition. I need a proper schema that tells me where to find what in such a way that I can traslate it to code.

What I think you'r seeing is a "mime" and "ispe" mp4 box as HEIF is ISOBMFF based. I would recommend looking at the file using a mp4 capable tool like mp4dump, HexFiend or fq (note: my tool). The "ispe" (Image Spatial Extents) box i probably what you want to read.

fq does no support ispe box yet but you could read it like this:

In this example the viewBox of the is 100 in width and the image also takes up 100% of the width. So, no matter the actual width of the image it will always fill the entire SVG.

The fits in the size of the viewBox of the that holds the image. I know the width is 100, so I made the clippath 70 in height and width plus the extra height that the rotation takes up. This matches kind of the height of the images (unknown at this point).

I replaced the content of the . It is more "transparent" what the clip path does and easier to manipulate.

QUESTION

Copy values from one XMP tag to another XMP tag

Asked 2021-Dec-12 at 16:57

I have a lot of images (JPG) with some metadata. I'm interested in these three tags, for example, from one of the images:

[XMP] FlightPitchDegree : 0.734793
[XMP] FlightRollDegree : -1.024403
[XMP] FlightYawDegree : 192.286436

I need to copy these values for each image to the next tags:

Xmp.Camera.Pitch Xmp.Camera.Roll Xmp.Camera.Yaw

Mostly for tag editing, I'm using ExifTool, but I can't find commands for copying values between tags inside one file. I'll be very appreciative of any recommendation.

Best, Andriy

ANSWER

Answered 2021-Dec-12 at 16:57

To copy from one tag to another you would use the redirection feature of the -TagsFromFile option. Basically it would be
exiftool "-TARGETTAG


You have the names of the SourceTags (FlightPitchDegree/FlightRollDegree/FlightYawDegree), you just need to figure out the exiftool names of your target tags.  I can find CameraPitch/CameraYaw/CameraRoll tags on the DJI Tags page, but those are not XMP tags.  The only other place I can find tags with similar names are part of the XMP-Camera group, which are not built into exiftool and you would have to download the pix4d.config file and use the -Config option to include those definitions.

Python PIL unexpected quit of process when cropping

I am working on a short script which should slice a tiff file in smaller pieces.


The files are bigger as typical (the biggest file has 16000 x 28800 pixels 1 bit depth)

My idea is, to crop each of this rectangles and save this as a new file, with the same resolution as the original image

It seams PIL and crop has some problems with LZW compression. Removing the compression with Photoshop makes the script running like expected.
