Crystal Report 與 pdf 的度量單位

Crystal Report 的單位為 TWIPS (twentieth of a point) [http://en.wikipedia.org/wiki/Twip], 1 twip = 1/1440 inch, they are independent of the number of pixels on the screen; to find out how many twips wide your document is, you check the page size you setup on the report (in inches let’s say, then multiply by 1440). And I’m not sure you can change this programmatically.

Anyway: if 1 inch = 1440 twips, 1 cm = 576 twips.

PDF 的單位如下，AbcPdf 也可設成 twips
This property holds the current measurement units. This property can take any of the following values:

points (PostScript Points) - 1/72 of an Inch
twips (Twentieths of a Point) - 1/20 of a PostScript Point

另外，PDF 的座標的原點在左下角，AbcPdf 可以設成由上往下。

電腦字型， 例如 14，轉換成 twips 為 14*20。
