JYImageTool
Useful image tools for iOS
Features
- Extract the primary color of the image(Multiple modes)
- Extract the image pixel color
- Contrast image is equal (based on pixel rather than image name)
- QRcode image generation and recognition
- Image compression
Usage
Extract the primary color of the image
UIColor *whiteColor = [UIColor colorWithRed:1.f green:1.f blue:1.f alpha:1.f];
// extract bright colors and avoid results if close to white color
self.colorArr = [self.imageView.image extractColorsWithMode:JYExtractModeOnlyDistinctColors avoidColor:whiteColor];Extract the image pixel color
UIColor *color = [self.imageView.image pixelColorAtLocation:point formImageRect:self.imageView.frame];Contrast image is equal
BOOL isEqual = [self.imageViewOne.image isEqualToImage:self.imageViewTwo.image];
if (isEqual) {
//...Do something..
}
else {
//...Do something..
}QRcode image generation and recognition
// Create QRcode image
UIImage *QRcodeImage = [UIImage QRCodeImageFromString:@"Job-Yang" imageSize:500];
// Recognition QRcode in the image
NSString *info = [QRcodeImage identifyQRCode];Image compression
// Compressed to 500KB
NSData *compressData = [self.originalImage compressImageToByte:500 * 1024];Installation

实用的iOS图片工具
特性
- 图片主色提取（包含多种提取模式）
- 图片像素点颜色提取
- 图片相同比较（基于图片像素而非图片名）
- 二维码图片生成与识别
- 图片压缩
Usage
图片主色提取
UIColor *whiteColor = [UIColor colorWithRed:1.f green:1.f blue:1.f alpha:1.f];
// 提取较附近更亮的主色，并忽略太接近白色的提取结果
self.colorArr = [self.imageView.image extractColorsWithMode:JYExtractModeOnlyDistinctColors avoidColor:whiteColor];图片像素点颜色提取
UIColor *color = [self.imageView.image pixelColorAtLocation:point formImageRect:self.imageView.frame];图片相同比较
BOOL isEqual = [self.imageViewOne.image isEqualToImage:self.imageViewTwo.image];
if (isEqual) {
//...Do something..
}
else {
//...Do something..
}二维码图片生成与识别
// 创建二维码图片
UIImage *QRcodeImage = [UIImage QRCodeImageFromString:@"Job-Yang" imageSize:500];
// 识别图片中的二维码
NSString *info = [QRcodeImage identifyQRCode];图片压缩
// 压缩到500KB
NSData *compressData = [self.originalImage compressImageToByte:500 * 1024];安装
