metadata

I found the command "mdls" which will show the metadata but I can't see how to delete it. I want to get rid of the comments "kMDItemFinderComment", "kMDItemWhereFroms" from my files. Is there a way to do this? I think you're looking for the xattr command, available in Terminal: xattr -pr com.apple.metadata:kMDItemFinderComment / that will print all the finder comments for all files on your boot volume. To delete, use the -d switch: xattr -dr com.apple.metadata:kMDItemFinderComment / You should test this out on a single file before running it in bulk. usage: xattr [-l] [-r] [-v] [-x] file [file

While saving screenshot image I am trying to change meta data of UIImage object for custom title and description of image. Imported headers #import <AssetsLibrary/AssetsLibrary.h> #import <ImageIO/ImageIO.h> #import <ImageIO/CGImageProperties.h> Inside my method NSData* dataOfImageFromGallery = UIImageJPEGRepresentation(imageToSave, 1.0); CGImageSourceRef imageSource = CGImageSourceCreateWithData((CFDataRef)dataOfImageFromGallery, NULL); NSMutableDictionary* metaData = (NSMutableDictionary *) CFBridgingRelease(CGImageSourceCopyPropertiesAtIndex(imageSource,0,NULL)); //--> metaData dictionary

I'm working on a service for a company project that handles image processing, and one of the methods is supposed to clean the metadata from an image passed to it. I think implementation I currently have works, but I'm not sure if it's affecting the quality of images or if there's a better way to handle this task. Could you let me know if you know of a better way to do this? Here's the method in question: public byte[] CleanMetadata(byte[] data) { Image image; if (tryGetImageFromBytes(data, out image)) { Bitmap bitmap = new Bitmap(image); using (var graphics = Graphics.FromImage(bitmap)) {

I have a Java application that creates a BufferedImage and saves it to disk as a JPEG. I'd really like to add a caption to the image. To prevent the image from getting crowded out by text on the image itself, it'd be great if I could write the caption to the JPEG's metadata. I've been searching all over the place for a solution, but haven't found anything satisfactory. Sanselan comes up a lot, but I haven't figured out how to use it properly. I found examples that modify existing metadata, but my files don't contain metadata as they are simply created from ImageIO.write() or Sanselan

I am using Woocommerce latest version 3.4.2. How can I get some order item metadata and assign them a custom value? I get meta data with a common array $item_product_data_array . I need to get a certain value - (Additional modification for the product). And assign custom sku. Example: I have coffe - sku 1001, in array - key [0] Product coffe have additional modification - sugar (meta data) Need found "Sugar" and assign him custom sku - 50005. [label] => Optionally select [value] => Array ( [0] => Cinnamon [1] => Sugar [2] => Mint ) That is, this additive should be in one cycle as a price or

Background: I'm streaming radio using double buffering approach for html shoutcast. I get metadata information from stream using http://www.smackfu.com/stuff/programming/shoutcast.html Problem I have three problems. 1- I already use a urlconnection and inputstream for listening radio. I don't want to open a new connection to retrieve metadata. But when I tried to get both from same inputstream, I couldn't listen radio anymore. I guess this is not possible and I have to use two seperate connection? Isn't it bad for performance? 2- When the application started, I retrieve the info of the current

How can i get it's metadata? You can use the ImageIO Framework like explained in QA1654 : To access the image properties you: create a CGImageSourceRef for your image. get a copy of the image properties dictionary by calling CGImageSourceCopyPropertiesAtIndex. access the values in the dictionary by calling CFDictionaryGetValue with the property key that you are interested in. The available keys are

My C# app syncs files from a remote document management system to a filesystem. The document management system has metadata (date of last audit, secrecy, author...) which is associated with each file but not stored WITHIN each file. The files can be anything (bmp, xwd, pdf, unknown binary) I want to make these metadata visible on the local Windows filesystem. But I can't store metadata WITHIN each file. For instance, changing the secrecy of a file must NOT modify the checksum of the file. What is the best way to store this metadata? I have heard about NTFS extended file attributes , is it

I've come to the point where I need to store some additional data about where a particular field comes from in my Lucene.Net index. Specifically, I want to attach a guid to certain fields of a document when the field is added to the document, and retrieve it again when I get the document from a search result. Is this possible? Edit: Okay, let me clarify a bit by giving an example. Let's say I have an object that I want to allow the user to tag with custom tags like "personal", "favorite", "some-project". I do this by adding multiple "tag" fields to the document, like so: doc.Add( new Field(
