ChinaCock界面控件介绍-TCCBarcodeCreator

条码生成器，可以生成各种条码，包括二维码。这是一个不可视控件。用起来依旧简单。

属性说明：

BarCodeColor:生成条码的颜色

BarcodeFormat:生成条码的类型，支持的条码类型：

BottomText:底部的文字

BottomTextColor:底部文字的颜色

BottomTextLinePaddiung：

BottomTextPadding:

BottomTextSize:

Code:条码的内容

ImageHeight:

ImageWidth:

IncludeLogo:

LogoBitmap:

ShowBottomText:是否显示底部文字

下面是生成一个二维码的代码：

BarcodeCreator.BarcodeFormat:=TCCBarcodeFormat.QR_CODE;
BarcodeCreator.Code:=edtCode.Text;
BarcodeCreator.BarcodeColor:=cbxBarcodeColor.Color;
BarcodeCreator.ImageWidth:=300;
BarcodeCreator.ImageHeight:=300;
BarcodeCreator.LogoBitmap:=self.LogoImage.Bitmap;
BarcodeCreator.IncludeLogo:=self.chxIncludeLogo.IsChecked;
BarcodeCreator.ShowBottomText:=chxShowBottomTex.IsChecked;
BarcodeCreator.BottomText:=self.edtBottomText.Text;
BarcodeCreator.BottomTextColor:=TAlphaColors.Red;
BarcodeCreator.BottomTextSize:=20;
BarcodeCreator.BottomTextPadding:=20;
BarcodeCreator.BottomTextlinePadding:=10;

self.BarcodeImage.Bitmap:=BarcodeCreator.CreateBarcode;//生成二维码图片

简单的都没什么可写的了。

下图是我实际的案例，把app的下载地址生成二维码：

delphi 10.3.3使用这个控件，进入app闪退，经作者提示，需要发布google-core-3.3.1.jar。

下面是闪退后捕获的日志：

有朋友问怎么发布这个google-core-3.3.1.jar：
1.在项目管理器窗口，右键，如下图，选择Add

 

 

 2.google-core-3.3.1.jar在作者的组件目.\ChinaCock\FMX\sdk

 

 

 就这样发布了！
