Adobe Flex 3: can I get TTF/OTF system fonts and embed at runtime?
Hi,
I'm a Stack Overflow noob so please go easy on me.
I've searched all day and found dozens of tutorial/examples on how to use [Embed] metadata or
Flash SWF files but they all tell me to either use a path in the source attrib or a text string in the systemFont attrib. What I want to do is; at runtime get all installed fonts on a given machine, determine which are TTF/OTF, embed them all and offer them in a comboBox. Something along these lines;
public function embedFonts():void{
try{
//get all device and embedded fonts
availableFonts = Font.enumerateFonts(true);
availableFonts.sortOn("fontName", Array.CASEINSENSITIVE);
for each(var thisFont:Font in availableFonts)
{
[Embed(systemFont=thisFont.fontName,
fontName=thisFont.fontName,
mimeType='application/x-font')]
//this bit need to create a unique variable name on each loop
var thisfont:Class;
}
}
catch(error:Error){
//if cant embed it's likely not to be TTF or OTF
//so move on to the next font.
}
}
Does anyone know a way?
Many, many thanks
You can't embed fonts at runtime.
And what would be the point?
Your swf runs on my machine, enumerates fonts on my machine, then embeds them
and offer them back to me? They are installed, use them directly, no need to embed.
So not only that is it not possible, but probably nobody will ever implement such a feature.

I have an old script that (among other things) converts a google document to pdf.
It used to work ok, but now two extra blank pages appear in the pdf version of the file.
I just discovered that this problem affects also the "download as pdf" menu option in google documents. There is a number of workarounds in that case, but I need a workaround for google-apps-script.
In this post the solution to a similar problem seems to involve a fine tuning of the page size. I tried something like that, but it does not trivially apply.
I also tried some other (kind of random) variations for the page size and margins, but to no avail.
Below I'm pasting a minimal working example. It should create a document file "test" and its pdf version "test.pdf" in your main drive folder.
Any help getting rid of the two extra pages is greatly appreciated.
Thanks
function myFunction() {
// this function
// - creates a google document "test",
// - writes "this is a test" inside it
// - saves and closes the document
// - creates a pdf version of the document, called "test.pdf"
//
// the conversion is ok, except two extra blank pages appear in the pdf version.
// create google document
var doc = DocumentApp.create('test');
var docFile = DriveApp.getFileById( doc.getId() );
// set margins (I need landscape layout)
// this is an attempt to a solution, inspired by https://stackoverflow.com/questions/18426817/extra-blank-page-when-converting-html-to-pdf
var body = doc.getBody();
body.setPageHeight(595.2).setPageWidth(841.8);
var mrg = 40; // in points
body.setMarginTop(mrg).setMarginBottom(mrg);
body.setMarginLeft(mrg).setMarginRight(mrg);
// write something
body.appendParagraph('this is a test').setHeading(DocumentApp.ParagraphHeading.HEADING2).setAlignment(DocumentApp.HorizontalAlignment.CENTER);
// save and close file
doc.saveAndClose();
// convert file to pdf
var docblob = docFile.getAs('application/pdf');
// set pdf name
docblob.setName("test.pdf");
// save pdf file
var file = DriveApp.createFile(docblob);
}
I found the source of the problem and a solution in this post on the google product forum, dating 8 months back.
The extra pages appear in the pdf if the option in view -> print layout is not checked.
I did some further tests, with my accounts and my colleagues'.
The results are consistent:
when view -> print layout is not checked two extra pages appear in the pdf version of the document
when view -> print layout is checked the pdf version of the document has the expected number of pages.
this setting affects also the documentApp services in Google Apps Script. That is: the above script produces the expected pdf version only if the "view->print layout" option in Google Documents is checked.
I do not see how this behaviour could be a "feature", so I think it's a bug. By the way "print layout" does not seem to have any visible effect on my documents (other than messing up the pdf version). I'm surprised that after 8 months the bug is still out there.
Number 3 above surprised me, because I did not think that an option set manually in a (any) google document would affect my scripts.
I'm currently looking for a way of setting the "print layout" option from inside the script. So far I had no luck with that.
I'm looking for some documentation of the new Xcode Source Editor Extensions in Xcode 8.
As far as I can see there is only the "documentation" found in the header file for XcodeKit. Would be great to get something that's more detailed and more official.
Very preliminary XcodeKit reference documentation is now available.
Our WWDC 2016 presentation introducing Xcode Source Editor Extensions remains the best walkthrough.
The very shortest version, however, is: Because App Extensions need to be embedded in an application, you need to first create a new macOS Cocoa Application, and then add a new Xcode Source Editor Extension to that application. Then the XcodeKit reference should help some in implementing that.
Not really a documentation but a good reference also
https://developer.apple.com/videos/play/wwdc2016/414/
Extensions, at the moment, are poorly documented. There are a lot of assumptions made (for example, did you know that you can execute the container app? Yup, it’s really nice for settings GUI - see this How To Execute Container App - Second Answer)
At the moment, there are a lot of things missing: for example, there isn’t a structure that shows the corresponding lines with the data object - though this is quickly created with the following code:
var matches: [NSTextCheckingResult] = []
do {
let regex = try NSRegularExpression(pattern: "\n", options: [])
matches = regex.matches(in: completeBuffer,
options: [],
range: NSMakeRange(0, completeBuffer.count))
}
catch {
}
This gives you the location of all the \n’s - you should be able to fill out the rest to give you starting and ending positions which should match up to the lines.
All in all, there is a lot to like about the extension, but there are quite a few things missing as well.
Currently the only available documentation is in the headers; there's nothing "unofficial" about them. If you have specific questions, please ask.
I'm trying to take and save a photo using a windows surface device.
I'm using the code below to take a photo and this work but I'd like to automatically create a directory on the device's local drive and save this photo there without any dialog prompts.
So the code I use to capture to photo is as follows:
CameraCaptureUI camera = new CameraCaptureUI();
StorageFile file = await camera.CaptureFileAsync(CameraCaptureUIMode.Photo);
if (file!=null)
{
using (IRandomAccessStream ras=await file.OpenAsync(FileAccessMode.Read))
{
BitmapImage source = new BitmapImage();
source.SetSource(ras);
imageBuildingPhoto.Source = source; // this is just an image control.
}
}
So after this I'd like to automatically save the photo to a new directory. e.g.
My Pictures\NewDirectory\Photo1.jpg
Anybody got any idea how I can do this?
This is a windows store application written using C#4.5 and XAML.
Thanks in advance
Use the CopyAsync method on the StorageFile object you get back (file). You can specify a directory and file name. If you need to create your own directory structure, you will need to enable access to the appropriate library in the Package Manifest then create it in code. You will then use the StorageFolder class and its CreateFolderAsync method to create folders.
http://aka.ms/30Days has some great resources for learning about scenarios like this. Might be worth checking out.
Your code will need to look to see if that folder exists and create it if it does not. Your app will need to declare the capability to access the user's Photos library in the app manifest, too.
To take a picture, your code is correct. I have a walkthrough in case you want to verify it against some other code: http://blog.jerrynixon.com/2012/10/walkthrough-capturing-photos-in-your.html
To interact with the file system, this can be tricky, but I have a longer write up on that if you want to reference it: http://blog.jerrynixon.com/2012/06/windows-8-how-to-read-files-in-winrt.html
The answer to your question is, yes you can. I have done it in my own apps. Now, it's just a matter of you implementing it in yours. You will find it to be pretty easy.
It would be great if the Petrel Plugin Manager could display our custom bitmap for each of our plugins - however, the Plugin.ImageResourceName property doesn't seem to have any effect.
public override string ImageResourceName { get { return "Blueback.Toolbox.Plugin.Toolbox.png"; } }
The image is embedded correctly (according to the documentation and ILDisAsm) - but Plugin Manager insists on using the generic image instead. Are there undocumented requirements on dimensions or format? The code snippets in the documentation mention both bmp and png, without demonstrating that the property actually works.
I haven't been able to locate an actual running sample in the SDK (only Module samples) nor in the code sample downloads (several Plugins here, but they return null for the resource name).
Can anyone provide a working sample or the missing key?
The image provided via Plugin.ImageResourceName is displayed in the Petrel License Dialog, and you are right, it is not displayed in Plugin Manager as it always uses the generic image to represent plugins. We will consider changing it in Petrel 2013.1.
I need to take an existing pdf file and programmatically fill in a list of form fields with text and then save the pdf without ever displaying it to the user.
For instance, if the pdf file contains fields named "LastName", and "FirstName" I would like to set the value of "FirstName" to "Louis" and then save the file.
I've been searching for a long time and can't find any guidance on even where to start since the iOS documentation (and most of the questions on here) seem geared towards displaying or creating pdf content instead of modifying it.
EDIT:
My main question is: Is it possible to open a pdf stream (I know how to do this) and copy each existing pdf dictionary item into a new pdf? I have not been able to find a way to write the dictionary items to a pdf.
I doubt that kind of functionality will ever be in the iOS frameworks. The reason most of the related info you can find "seem[s] geared towards displaying or creating pdf content instead of modifying it" is because that's what the vast majority of use cases will want or need for PDF functionality.
You'll need to find a 3rd party library that can open up PDFs, fill out the AcroForm fields, and then stamp out a PDF. I use iText on Java (there is also iTextSharp for C#) but I don't know of anything for Objective-C.
Once you find that library, you'll need to integrate it into your project. There are undoubtedly several related questions/answers here on SO for whatever version of the SDK you're using.
This would be easier to do with a HTML page. If you wish to use a HTML page instead of a .pdf form then thius is how you would go about doing it:
[field1 setText:#"Field 1 Text"];
[field2 setText:#"Field 2 Text"];
NSString *result;
result = [webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:#"$('#field1').val('%#');", field1.text]];
result = [webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:#"$('#pfield2').val('%#');", field2.text]];
result = [webView stringByEvaluatingJavaScriptFromString:#"$('#submitbutton').click();"];
You would need to create two UILabels or UITextFields and call them "field2" and "field2" in your .h file. You can then find the ID of the field you need to replace e.g. #field1 and then put it where I have put "#field1" and again for the second field where I have put "#field2". There also needs to be a UIWebView with the page already loaded. This code is to be used after the UIWebView page has been loaded. Maybe do the following:
-(void)webViewDidFinishLoad:(UIWebView *)webView {
// Insert above code here
}
You probably need a full understanding of Javascript if you want to do this for the whole form, but this should get you started.
Hope that helps you.
