PDKKit html渲染

Question

我正在使用pdfkit从ruby中的html生成pdf。我能够生成pdf，但pdf上的渲染文本有一些不均匀间隔的字符，即使html渲染是完美的。

def self.generate_invoice
      content = File.read( "#{Rails.root}/engines/restaurant_service/app/views/restaurant_service/settlement_mailer/settlement_invoice.html.erb")
      template = ERB.new(content)  
      set_margin = 0.1.to_s
      kit = PDFKit.new(template.result(binding), :page_size => 'Letter',:margin_top => set_margin+'in', :margin_right => set_margin+'in', :margin_bottom => set_margin+'in', :margin_left => set_margin+'in')
      kit.to_file(file_path)
    end

Answer 1

您可以在config / initializers / pdfkit.rb

中添加以下行

NSArray *arr1 = [pJson1 objectForKey:@"Response"];
        for (int i=0; i<arr1.count; i++)
    {
        int yval;
        int x ;
        btnNew = [[UIButton alloc]initWithFrame:CGRectMake(0,yval, 50, 30)];
        btnNew.backgroundColor = [UIColor blackColor];
        NSString *str = [NSString stringWithFormat:@"%@",[[arr1 objectAtIndex:i]objectForKey:@"name"]];
        [btnNew setTitle:str forState:UIControlStateNormal];
        btnNew.center = CGPointMake(160.0, 240.0);
        CGSize stringsize = [str sizeWithFont:[UIFont systemFontOfSize:14]];
        //or whatever font you're using
        [btnNew setFrame:CGRectMake(5,yval+10,100, 20)];
        btnNew.tag = i;
        [self.categoryView addSubview:btnNew];
        x += 2;
        yval +=10;
    }

然后重新启动服务器。
