QUESTION
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.

Answered 2022-Mar-24 at 08:47What 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:

My purpose is like this with css:
Here is the .svg file: https://svgshare.com/i/dfw.svg
Here is the svg code
...ANSWER
Answered 2022-Jan-25 at 14:46In 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.

Does php support webp image metadata?
Specifically, I want to be able to read and write XMP and EXIF metadata for webp images natively in php code.
I have been experimenting with the below code and it is giving me a "File not supported in" warning.

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 16:57To 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.

I have a simple table with four columns. Data for column B is imported via json. I simply wish to multiply the two and present them in column D.
How can I multiply the value in column B times the value in column C and present it in column D?
The working version is currently at http://crrdlx.websavvy.work/hivetiptokens/
and shows real-time data in column B. (image below)
FYI, some of the code (code below) in the section commented "HE tip token calculations" is from another script I use and doesn't apply here.
