I am making a text editor for the purpose of learning.
I would like to create a custom file format to be rendered by this app.
There would be a JSON file with all the elements such as tables, images defined in it, and an assets folder with images and other assets to be referenced in the JSON file, so the app could render them.
How would I make such a format ? Something that looks like app bundles on MacOS where they look and feel like a file but are in reality a bundle with multiple files and a standard directory structure.

Is there any way to use images in the format .png or another format, and then compile these images so that they are not within the folder Resource of this project? I've seen several programs using many of the images as icons but when you open the folder resource the only image I see is the icon of the program.
If items such as standard system icons are used you only need their paths (since they would already be installed), otherwise the image files need to be included in the project.
In our project we generate multiple swift files when using the file xctemplate configuration. However, with this configuration, there is no icon displayed in Xcode when generating the files (see attached image). We did try to add two images to the template folder: TemplateIcon-png and TemplateIcon#96.png which yielded no success. Is it possible to use a custom icon for file templates in Xcode?
Not sure if you're still looking for an answer to this, but you should be able to create an .icns icon package named TemplateIcon.icns. This should contain your template image(s) to be displayed in the new project picker.
I suspect your issue was trying to use the PNG assets directly.
See the Base Acceptance Testing Bundle for an example. It is part of the OCSlimProjectXcodeTemplates repository.
We have a Cocoa Mac OS X application in which we want to bundle around 500 images. Each image is around 10kb so size isn't a problem.
These images are not exactly resources in the app, they are sample images.
Basically, we have simple button that would let the user copy these images to a directory.
The solution also needs to be "dump in, dump out" -- so we don't want to store individual image file names somewhere in our application; we just want to have a directory of images that can be copied.
How do I package these into my application?
The question turns into: How do I make a directory resource containing the images.
In our case everything gets flattened into the MyApp.app/Contents/Resources and this approach would require us to put image names in the app so that we can copy those.
Put the images into a folder. Drag the folder into your project in Xcode. In the resulting dialog, make sure you copy, make sure you create a folder reference, and make sure you add to your app target. Done. Now the folder is part of your app bundle and you can refer to it from your code without knowing anything about its contents.
The folder /Library/Application Support is for support files that, if deleted, would not affect the execution of an application. I would suggest this is ideal for your product's sample images.
As Apple's documentation states for Application Support:
Use this directory to store all app data files except those associated with the user’s documents. For example, you might use this directory to store app-created data files, configuration files, templates, or other fixed or modifiable resources that are managed by the app. An app might use this directory to store a modifiable copy of resources contained initially in the app’s bundle.
So, use pkgbuild / productbuild to install them to /Library/Application Support/<ProductName>/
Because size is not an issue, you can just put all your sample images in separate Asset Catalog file.
my question is quite simple.
I have a Qt application with a Gui developed with QML.
My back-end side generates and saves jpg images in a folder called /images .
I am able to send from C++ to QML the strings holding the name of the images that I want to show. Sadly my QML Image object doesn't display anything.
It seems that if an image can be displayed only if it has been previously declared in the qml.qrc file.
Sadly, again, qrc files do not support wildcards yet!
https://bugreports.qt.io/browse/QTBUG-1400
Is there a workaround?
The name of the images are not fixed, they are generated with certain runtime values i.e. timestamp.
Thank you
By default it will search the image source in the qrc file. To make it go to the actual file system, prepend a file:/// to the path.
I have a Ruby app which is an Image Resizer. It uses the RMagick gem to do this. The app asks the user to upload a file, and then resizes it and saves the newly generated file.
It seems that Sinatra by default puts all uploaded files into the 'uploads' directory, and the newly generated file also seems to be saved there. I am assuming this is default behavior, not sure how to change this, but it isn't an immediate problem at the moment (although if you know how to do this, that would be appreciated too).
Now, in my 'success.haml' page which is displayed after the file is generated correctly, I am trying to display the newly generated image with a simple img tag. The path to the file is found in #filepath, so when I did:
%img(src=#filepath)
the HTML rendered (when inspected using Firebug) is correctly showing
<img src="uploads/filename.jpg">
and this file does indeed exist in my folder structure. However, the image appears broken.
Any ideas on how to overcome this problem?
Thank you.
Relative urls (uploads/filename.jpg) are called so because they are relative to web root. In Sinatra this is the public folder. By default it's located in your app directory and called public. But you can override that.
set :public_folder, 'my_root' # this will make my_root dir the web root.
So, to make your uploads visible to the internet, put them into your public folder.
