c# - 在 Acumatica 中确认发货时如何旋转从承运人检索到的发货标签图像？

UPS 运输标签 API 没有选项来指定运输标签图像的旋转度数。我们将通过自定义ShipmentEntry图形/BLC来解决这个问题Shipment Entry screen (SO302000)。

当前工作流程不会有任何变化（最终用户视角）。当在 Acumatica 中确认货件时，会生成标签并从 UPS 检索，在此过程中，我们的自定义将顺时针旋转检索到的标签（仅当 Ship-Via on Shipment 使用 UPS 插件且标签格式为 GIF 时）顺时针 90 度。此 UPS 标签将与通过其他插件（FedEx 和 Stamps.com）生成的标签对齐。并且不需要在报告级别进行调整。

Shipping Label 是通过Graph/BLCShipPackages中的虚拟方法生成的。ShipmentEntry因此，我们将ShipPackages在 Graph/BLC 的 Graph/BLC 扩展中覆盖虚拟方法ShipmentEntry。

public class SOShipmentEntryRotateGIFLabelExt : PXGraphExtension<SOShipmentEntry>
{
     public delegate void ShipPackagesBaseDelegate(SOShipment shiporder);

     [PXOverride]
     public void ShipPackages(SOShipment shiporder, ShipPackagesBaseDelegate BaseInvoke)
     {
         //Custom code to rotate image if carrier is UPS and label format is GIF                 
         //Invoke base method 
         BaseInvoke(shiporder);
     }
}

Acumatica 中的文件附件是通过UploadFileMaintenanceGraph/BLC 执行的。我们将通过将DAC的RowInserted事件处理程序添加到图中来扩展逻辑。UploadFileRevisionUploadFileMaintenance

因为UploadFileMaintenanceBLC 实例是在其中创建的，ShipPackages并且在执行之前不可用，所以我们将InstanceCreated在类的静态集合中添加一个委托PXGraph。

在初始化 BLC 实例时执行的委托中UploadFileMaintenance，我们将向Graph/BLC 实例的RowInserted集合添加一个事件处理程序。UploadFileMaintenance

public class SOShipmentEntryRotateGIFLabelExt : PXGraphExtension<SOShipmentEntry>
{
    public delegate void ShipPackagesBaseDelegate(SOShipment shiporder);

    [PXOverride]
    public void ShipPackages(SOShipment shiporder, ShipPackagesBaseDelegate BaseInvoke)
    {
        #region Custom-code-to-rotate-retrieved-Label

        PXGraph.InstanceCreated.AddHandler<UploadFileMaintenance>((fileGraph) =>
        {
            fileGraph.RowInserted.AddHandler<UploadFileRevision>((sender, e) =>
            {
                UploadFileRevision fileData = (UploadFileRevision)e.Row;
            });
        });

        #endregion
        //Invoke base method 
        BaseInvoke(shiporder);
    }
}

在RowInserted事件处理程序中，我们获取UploadFileRevision正在处理的数据记录并检索运输标签图像并旋转它。

最后我们调用基本方法。
