安装
BKAsciiImage 通过 CocoaPods 提供。要安装它，只需将以下行添加到您的 Podfile 中：
pod "BKAsciiImage"用法
使用 BKAsciiConverter 类
导入 BKAsciiConverter 头文件
#import <BKAsciiImage/BKAsciiConverter.h>创建一个 BKAsciiConverter 实例
BKAsciiConverter *converter = [BKAsciiConverter new];同步转换
UIImage *inputImage = [UIImage imageNamed:@"anImage"];
UIImage *asciiImage = [converter convertImage:inputImage];后台转换，提供一个完成块。完成块将在主线程上被调用。
[converter convertImage:self.inputImage completionHandler:^(UIImage *asciiImage) {
// do whatever you want with the resulting asciiImage
}];转换为 NSString
NSLog(@"%@",[converter convertToString:self.inputImage]);
// asynchronous
[converter convertToString:self.inputImage completionHandler:^(NSString *asciiString) {
NSLog(@"%@",asciiString);
}];转换器选项
converter.backgroundColor = [UIColor whiteColor]; // default: Clear color. Image background is transparent
converter.grayscale = YES; // default: NO
converter.font = [UIFont fontWithName:@"Monaco" size:13.0]; // default: System font of size 10
converter.reversedLuminance = NO; // Reverses the luminance mapping. Reversing gives better results on a dark bg. default: YES
converter.columns = 50; // By default columns is derived by the font size if not set explicitly使用 UIImage 分类
导入头文件
#import <BKAsciiImage/UIImage+BKAscii.h>使用提供的分类方法
UIImage *inputImage = [UIImage imageNamed:@"anImage"];
[inputImage bk_asciiImageCompletionHandler:^(UIImage *asciiImage) {
}];
[inputImage bk_asciiStringCompletionHandler:^(NSString *asciiString) {
}];
[inputImage bk_asciiImageWithFont: [UIFont fontWithName:@"Monaco" size:13.0]
bgColor: [UIColor redColor];
columns: 30
reversed: YES
grayscale: NO
completionHandler: ^(NSString *asciiString) {
// do whatever you want with the resulting asciiImage
}];高级用法
默认情况下，亮度值通过以下方式映射到字符串：
NSDictionary *dictionary = @{ @1.0: @" ",
@0.95:@"`",
@0.92:@".",
@0.9 :@",",
@0.8 :@"-",
@0.75:@"~",
@0.7 :@"+",
@0.65:@"<",
@0.6 :@">",
@0.55:@"o",
@0.5 :@"=",
@0.35:@"*",
@0.3 :@"%",
@0.1 :@"X",
@0.0 :@"@"
};您可以使用自己的映射字典来实例化一个转换器
NSDictionary *dictionary = @{ @1.0: @" ",
@0.7 :@"a",
@0.65:@"b",
@0.6 :@"c",
@0.55:@"d",
@0.5 :@"e",
@0.35:@"f",
@0.3 :@"g",
@0.1 :@" ",
@0.0 :@" "
};
BKAsciiConverter *converter = [[BKAsciiConverter alloc] initWithDictionary:dictionary];
UIImage *inputImage = [UIImage imageNamed:@"anImage"];
UIImage *asciiImage = [converter convertImage:inputImage];
