问题 In writing some image processing routines in Matlab, I found that I don't know how to write metadata in to a newly processed and saved image. To keep it simple, my flow is as follows: image = imread('Base_Pic.jpg'); image_info = imfinfo('Base_Pic.jpg'); %Process image... %Update metadata... imwrite(image,'Updated_Image.jpg','JPEG','Quality',100); I basically want the newly processed image to have all the same metadata attributes as the original image, with a few fields updated of course. How

问题 Say I have the following code: (defn ^{:graph-title "Function 1"} func-1 [x] (do-something-with x)) (defn get-graph-title [func] (str ((meta func) :graph-title))) I expect this to return "Function 1", but it returns nil. I think this stems from the following difference, which I don't totally comprehend: (meta func-1) => {:ns some-ns-info, :name func-1} (meta #'func-1) => {:ns some-ns-info, :name func-1, :graph-title "Function 1"} Can someone explain this to me? 回答1: The metadata is attached

Creating a jpeg file with metadata

问题 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,

Store metadata outside of file: Any standard approach on modern Windows?

问题 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.

Get metadata of local mp3 file using html5 filesystem api

问题 I was trying to get the title and artist (and other metadata eventually) of each mp3 file in a directory. Currently the code I have appends the div "thelist" with the file name of the mp3 file. How could I go about getting the title and artist properties/tags of the file instead of the entire file name? Here is my code: <!DOCTYPE html> <html> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Get Directory</title> <script type="text/javascript" src="jquery.min

PHP: Read TrueType/OpenType metadata of the font file

由 时间秒杀一切 提交于 2019-12-21 17:24:01
问题 How to read the fonts details? For example, fonts contain information like copyright, family name, designer, version, and more in their metadata.

For example, a typical font could contain western, swedish and romain language support, and have hundreds of glyphs. It should support truetype and opentype font files. Thanks in advance for any help on achieving
