在乳胶上绘制此图

Question

有没有绘制类似下图的示例代码？黑色图像是我想要插入的图片。

我有一个示例代码。

1) 如何将矩形更改为其他形状？例如不分割的梯形/矩形。

2）如何在文本所在位置插入图片

:Title: System Combination
:Author: Harish K Krishnamurthy

A block diagram of system combination technique of combining several Automatic Speech Recognition Systems (ASRs) to determine best word sequence outputs is shown here. The training and validation phase are the important phases.
