creating a PFont from custom path source

in Programming Questions • 2 years ago

Hi all,

I have doubts in how can i create an PFont from custom path instead data folder;
In specific project;

I want to manage data folder according data type, with subfolders, like:

data/images
data/fonts
data/xml

PFont class calls to data/somefile and give-me expected errors if i do

PFont pFont = PApplet.loadFont("data/font/curseCasualJVE.ttf");

in Sketch class created i call:

public class SketchApplet extends PApplet implements Sketch{
/*
* some code
*/
//Configure the size
@Override
public void setup(){
size(500, 500);
if(LOG){
Log.d(TAG, "sketch size");
Log.i(TAG, "width: "+this.width);
Log.i(TAG, "height: "+this.height);
}
    //Configure the message features
           String filename = "/data/font/curseCasualJVE.ttf";

           PFont pFont = null;
           try{
               pFont = new PFont(createInput(new File(filename)));

               if(LOG)
                   Log.d(TAG, "loading font");
                   Log.i(TAG, pFont.getName());

               textFont(pFont);
               textMode(PConstants.SCREEN);
               textAlign(PConstants.CENTER);
           } catch (Exception e) {
               if(LOG)
                   Log.d(TAG, "Exiting "+toString());
                   Log.i(TAG, "path: "+filename);
                   Log.i(TAG, "PFont: "+(!pFont.equals(null)?pFont.getName():"null"));
                   Log.i(TAG, "\tsize: "+pFont.getSize());
               die("Could not load font " + filename + ". " +
                          "Make sure that the font has been copied " +
                          "to the data folder of your sketch.", e);
           }finally{
               if(!this.exitCalled)
                   this.exit();
           }
}

I have this stack trace:

How can I acess custom src to PFont instance?

Thanks

loadFont is relative to data folder already, don't put it in the relative path.

But is possible to trick and use custom path with other methods?

I'm trying using :

//InputStream input = createInputRaw("folder/file.exten");
InputStream input = createInput("folder/file.exten");
PFont pFont = new PFont(input);

but i stil receive an NullPointerException or FileNotFoundException :P

Have you tried phi.lho's suggestion?

Instead of

PFont pFont = PApplet.loadFont("data/font/curseCasualJVE.ttf");

use

PFont pFont = PApplet.loadFont("font/curseCasualJVE.ttf");

If you want to access a file outside the sketch folder I suspect (not 100% sure) you need the full pathname.

Is possible to be a problem of understand TTF file?

ttf stands for "True Type Font" and is the format most of your computer system fonts are stored in.

In Processing the loadFont expects the fonts to be in a different format (.vlw)

To create a vlw font from your ttf font select Create Font... from the Tools menu in Processing.

is possible to do this in code?

i'm using eclipse instead Processing IDE ... :P

Use createFont() instead of loadFont(). It accepts TTF files.

Ow, now works, thanks!

PFont pFont = null;
String path = "font/SortsMillGoudy-Italic.ttf";
try {
pFont = createFont(path, 30);
if(LOG)
Log.d(TAG, "Font: "+pFont.getName());
Log.i(TAG, "size: "+pFont.getSize());
Log.i(TAG, "PostScript name: "+pFont.getPostScriptName());
} catch (Exception e) {
// TODO Auto-generated catch block
Log.e(TAG, "error on acess "+path, e);
Log.w(TAG, "ending", "");
exit();
}

No need for the try/catch: most, if not all, Processing functions won't throw exceptions: for example createFont already does a try/catch and just uses e.printStackTrace(); to dump it.
