I created a droplet that is supposed to pass a file (which is being dropped on the droplet) to a website in safari in a file dialog.
I managed most of it... but the file path I get through "theDroppedItems" starts with file:// and it also includes characters like %20 and ~ and more weird characters.
Is there a way to convert this to a "real path" that safari accepts?
solved:
set inx to item 1 of theDroppedItem
set iny to POSIX path of inx
I am converting a .ttf/.otf font file reader in Lua 5.2 from Windows to MacOS and also want to add support for .suit font files which include ttf fonts.
Plain .ttf/.otf files now work fine, but already the reading of a .suit file doesn't work.
Any ideas on how to read the bytes of the .suit font on MacOS?
Does it have to do with a file name alias?
local input = assert(io.open("/Library/Fonts/Tahoma.ttf", "rb"))
local data=input:read("*all")
print(string.byte(data,1)) --prints the correct value 0
io.close(input)
local input = assert(io.open("/Library/Fonts/Maestro.suit", "rb"))
local data=input:read("*all")
print(string.byte(data,1)) --prints nothing
io.close(input)
The upper part (Tahoma) prints the correct first byte value 0, while the bottom part prints nothing, although I would have expected the value 0.
When I use string.len(data), it shows the correct value for Tahoma, but 0 for Maestro, although it should be something like 46k.
See https://apple.stackexchange.com/questions/8455 .suit is not a folder, but it can be addressed like a folder. To open the font part in the .suit file use:
local file=io.open("/Library/Fonts/Maestro.suit/..namedfork/rsrc","rb")
Does anyone know how to display a local image in markdown? I don't want to set up a webserver for that.
I try the following in markdown, but it doesn't work:
I suspect the path is not correct. As mentioned by user7412219 ubuntu and windows deal with path differently. Try to put the image in the same folder as your Notebook and use:
On windows the desktop should be at: C:\Users\jzhang\Desktop
The following works with a relative path to an image into a subfolder next to the document:
Solution for Unix-like operating system.
STEP BY STEP :
Create a directory named like Images and put all the images that will be rendered by the Markdown.
For example, put example.png into Images.
To load example.png that was located under the Images directory before.
Note : Images directory must be located under the same directory of your markdown text file which has .md extension.
To add an image in markdown file the .md file and the image should be in the same directory. As in my case my .md file was in doc folder so i also moved the image into the same folder. After that write the following syntax in .md file
like 
This has worked for me.
The best solution is to provide a path relative to the folder where the md document is located.
Probably a browser is in trouble when it tries to resolve the absolute path of a local file. That can be solved by accessing the file trough a webserver, but even in that situation, the image path has to be right.
Having a folder at the same level of the document, containing all the images, is the cleanest and safest solution.
It will load on GitHub, local, local webserver.
images_folder/img.jpg < works
/images_folder/img.jpg < this will work on webserver's only (please read the note!)
Using the absolute path, the image will be accessible only with a url like this: http://hostname.doesntmatter/image_folder/img.jpg
if image has bracket it won't display
.png)
rename the image and remove brackets
Update:
if you have spaces in the file path, you should consider renaming it too or if you use JavaScript you can encode it using
encodeURIComponent(imagePath)
Also, always try to save images and files alike with lowercase, please develop that habit, just my personal view though
Adding a local image worked for me by like so: 
Without the file:// prefix it did not work (Win10, Notepad++ with MarkdownViewer++ addon)
Edit: I found out it also works with html tags, and that is way better:
<img src="file://IMG_20181123_115829.jpg" alt="alt text" width="200"/>
Edit2: In Atom editor it only works without the file:// prefix. What a mess.
Depending on your tool - you can also inject HTML into markdown.
<img src="./img/Isolated.png">
This assumes your folder structure is:
├── img
└── Isolated.jpg
├── README.md
Edited:
Working for me ( for local image )
tree
├── doc
└── jobsSystemSchema.jpg
├── README.md
markdown file README.md is at the same level as doc directory.
In your case ,your markdown file should be at the same level as the directory files.
Working for me (absolute url with raw path)
NOT working for me (url with blob path)
Just add the relative image file route from the markdown file
This worked for me in ubuntu:
Markdown file is in:
/home/gps/Documents/Markdown/
Image file is in:
/home/gps/Pictures/
To my knowledge, for VSCode on Linux, the local image can be normally displayed only when you put the image into the same folder as your .md post file.
i.e. only  or  will work.
Even the absolute path like also doesn't work.
In Jupyter Notebook Markdown, you can use
<img src="RelPathofFolder/File" style="width:800px;height:300px;">
Another possibility for not displayed local image is unintentional indent of the image reference - spaces before .
This makes it 'code block' instead of 'image inclusion'. Just remove the leading spaces.
You may find following the syntax similar to reference links in markdown handy, especially when you have a text with many displays of the same image:
![optional text description of the image][number]
[number]: URL
For example:
![][1]
![This is an optional description][2]
[1]: /home/jerzy/ComputerScience/Parole/Screenshot_2020-10-13_11-53-29.png
[2]: /home/jerzy/ComputerScience/Parole/Screenshot_2020-10-13_11-53-30.png
I've had problems with inserting images in R Markdown. If I do the entire URL: C:/Users/Me/Desktop/Project/images/image.png it tends to work. Otherwise, I have to put the markdown in either the same directory as the image or in an ancestor directory to it. It appears that the declared knitting directory is ignored when referencing images.
Either put the image in the same folder as the markdown file or use a relative path to the image.
just copy the image and then paste it, you will get the output
The basic syntax is . In my case, I used image name as Any\ Image\ of\ your\ choice.png in  instead of  and it was not working. So I would say make sure to check the image directory and also image name doesn't contain spaces if so use underscore(_) instead of space.
Faced issue while using markdown in Jupyter notebook in Ubuntu 18.04.
I got a solution:
a) Example Internet:
b) Example local Image:
TurboByte
I have a process that creates Windows internet shortcut files (.url). The files are encoded in UTF-8. The files contain an [InternetShortcut] section, where a URL= is specified. In this case, these are file:/// protocol URLs, which allow people to open paths on their LAN. The URLs are all UNC paths.
Normally the process works fine. But when a UNC path contains Unicode characters, such as the "í" from the code sample below, Windows is unable to "find" the URL when an end user tries to open the internet shortcut from Windows Explorer:
A sample file follows:
[InternetShortcut]
URL=file:///\\lt-splourde\d$\POC\Montería Test\
IconIndex=1
When I open the sample .url file above with a text editor, I see the path with the proper Unicode characters. But when I try to open the file from Windows Explorer, in order to access the path, Windows reports that it is unable to access the path, and it seems to mangle the Unicode characters.
The source code that creates these shortcuts follows:
private void CreateShortcutAsUrl(string uncRootPath, string name, string path, int projectId)
{
path = path + (path.EndsWith(#"\") ? "" : #"\");
using (StreamWriter writer = new StreamWriter(
String.Format(#"{0}\{1}\{2}.url", uncRootPath,
ShortcutsDirectory, new FileServerController().SanitizeNameForDirectory(name)),
false, Encoding.UTF8))
{
writer.WriteLine(#"[InternetShortcut]");
writer.WriteLine(#"URL=file:///" + path);
writer.Flush();
}
}
Does anyone know of a solution for this issue?
Thanks!
(I had posted this on superuser originally, but I feel like the content is more programmer oriented)
Try the .NET equivalent of InternetCanonicalizeUrl, which is System.Uri.EscapeUriString, so something like this (assuming your URI is in szOriginalString
String szEscapedString = System.Uri.EscapeUriString(szOriginalString);
Then write szEscapedString as the URI instead of the original.
I have a set of 100 jpg images named consecutively and I want to add them up to get a single image. I have seen the answer from here, but it does not run with me, what happened?
Here is the code:
im = imread('C:\Documents and Settings\1026175117_1.jpg');
for i = 2:10
im = imadd(im,imread(sprintf('C:\Documents and Settings\1026175117_%d.jpg',i)));
end
im = im/1000;
imshow(im,[]);
Here's the error message:
Error using ==> imread
Can't open file "C:" for reading;
you may not have read permission.
Backslash is a special character for sprintf() and needs to be escaped. Either use "\\" instead of "\" or try constructing your file paths another way. fullfile() is a good way to do it, so you only have to use sprintf for the file name part. Also see help sprintf.
