public final class EscherGraphics2d
extends java.awt.Graphics2D
Important:
One important concept worth considering is that of font size. One of the difficulties in converting Graphics calls into escher drawing calls is that Excel does not have the concept of absolute pixel positions. It measures it's cell widths in 'characters' and the cell heights in points. Unfortunately it's not defined exactly what a type of character it's measuring. Presumably this is due to the fact that the Excel will be using different fonts on different platforms or even within the same platform.(将 Graphics2d 调用转换为 escher 调用。翻译是有损的,因此许多功能不受支持,有些功能尚未实现。如果有疑问,请测试您希望拨打的特定电话。图形调用总是被绘制到 EscherGroup 中,因此需要创建一个。重要:值得考虑的一个重要概念是字体大小。将 Graphics 调用转换为 escher 绘图调用的困难之一是 Excel 没有绝对像素位置的概念。它以“字符”为单位测量其单元格宽度和以点为单位的单元格高度。不幸的是,它没有准确定义它正在测量的字符类型。这大概是由于 Excel 将在不同平台上甚至在同一平台内使用不同的字体。由于这个约束,您必须计算verticalPointsPerPixel。这是当您发出诸如 drawString() 之类的命令时字体应该被缩放的量。计算此值的一个好方法是使用以下公式: multipler = groupHeightInPoints / heightOfGroup 通过计算形状边界框的 y 坐标之间的差异,可以相当简单地计算组的高度。组的高度可以通过使用称为 HSSFClientAnchor.getAnchorHeightInPoints() 的便利来计算。)Because of this constraint you have to calculate the verticalPointsPerPixel. This the amount the font should be scaled by when you issue commands such as drawString(). A good way to calculate this is to use the follow formula:
multipler = groupHeightInPoints / heightOfGroupThe height of the group is calculated fairly simply by calculating the difference between the y coordinates of the bounding box of the shape. The height of the group can be calculated by using a convenience called
HSSFClientAnchor.getAnchorHeightInPoints()
.
