FBDigitalFont

This library includes some kind of digital styled font drawer. They're not TTF files or something. They just draw fonts with CoreGraphics. So, you don't need to worry about redistribution license of font files when you release your application.

Example

Bitmap Font

supporting A-Z, 0-9

LCD Font

supporting 0-9, dash

Square Font

supporting A-Z, 0-9, dash

GLOWING EFFECT

I guess this kind of fonts have high affinity to glowing effects. So I support same effect as FBGlowLabel.

All you have to do is to set 4 properties.

• glowColor
• innnerGlowColor
• glowSize
• innerGlowSize

APPLICATION EXAMPLE

In my app, "Flashback", Most of digital styled fonts are provided by this technique.

SETTING UP

If you use CocoaPods, add following line into your Podfile

pod 'FBDigitalFont', :git => 'https://github.com/lyokato/FBDigitalFont.git'

or directly git clone or download from this page.

IMPLEMENTATION

This includes some UIView classes which is customized to handle these fonts easily.

• FBBitmapFontView
• FBLCDFontView
• FBSquareFontView

Or If you want, you can directly use drawer classes.

• FBBitmapFont
• FBLCDFont
• FBSquareFont

Each of view classes require you to call resetSize method after modified properties to adjust view size according to modified parameters. Don't forget about this.

FBBitmapFontView

#import <FBDigitalFont/FBBitmapFontView.h>

- (void)setupBitmapFontView
{
    CGRect frame = CGRectMake(10, 60, 300, 50);
    FBBitmapFontView *v = [[FBBitmapFontView alloc] initWithFrame:frame];
    v.text = @"BITMAP";
    v.numberOfBottomPaddingDot = 1;
    v.numberOfTopPaddingDot    = 1;
    v.numberOfLeftPaddingDot   = 2;
    v.numberOfRightPaddingDot  = 2;
    v.glowSize = 20.0;
    v.innerGlowSize = 3.0;
    v.edgeLength = 5.0;
    [self.view addSubview:v];
    [v resetSize];
}

• dotType
• edgeLength
• margin
• numberOfLeftPaddingDot
• numberOfTopPaddingDot
• numberOfRightPaddingDot
• numberOfBottomPaddingDot
• numberOfPaddingDotWithinDigits
• offColor
• onColor
• glowColor
• innerGlowColo
• glowSize
• innerGlowSize
• text

FBLCDFontView

#import <FBDigitalFont/FBLCDFontView.h>

- (void)setupLCDFontView
{
    CGRect frame = CGRectMake(40, 150, 300, 50);
    FBLCDFontView *v = [[FBLCDFontView alloc] initWithFrame:frame];
    v.text = @"20141231";
    v.lineWidth = 4.0;
    v.drawOffLine = YES;
    v.edgeLength = 20;
    v.margin = 10.0;
    v.backgroundColor = [UIColor blackColor];
    v.horizontalPadding = 20;
    v.verticalPadding = 14;
    v.glowSize = 10.0;
    v.glowColor = UIColorFromRGB(0x00ffff);
    v.innerGlowColor = UIColorFromRGB(0x00ffff);
    v.innerGlowSize = 3.0;
    [self.view addSubview:v];
    [v resetSize];
}

• drawOffLine
• edgeLength
• margin
• lineWidth
• horizontalPadding
• verticalPadding
• glowSize
• innerGlowSize
• lineColor
• offColor
• glowColor
• innerGlowColor
• text

FBSquareFontView

#import <FBDigitalFont/FBSquareFontView.h>

- (void)setupSquareFontView
{
    CGRect frame = CGRectMake(10, 240, 300, 50);
    FBSquareFontView *v = [[FBSquareFontView alloc] initWithFrame:frame];
    v.text = @"SQUARE";
    v.lineWidth = 3.0;
    v.lineCap = kCGLineCapRound;
    v.lineJoin = kCGLineJoinRound;
    v.margin = 12.0;
    v.backgroundColor = [UIColor blackColor];
    v.horizontalPadding = 30;
    v.verticalPadding = 14;
    v.glowSize = 10.0;
    v.glowColor = UIColorFromRGB(0x00ffff);
    v.innerGlowColor = UIColorFromRGB(0x00ffff);
    v.lineColor = UIColorFromRGB(0xffffff); // 0xffdd66
    v.innerGlowSize = 2.0;
    v.verticalEdgeLength = 12;
    v.horizontalEdgeLength = 14;
    [self.view addSubview:v];
    [v resetSize];
}

• horizontalEdgeLength
