A Note on Metafile pictures

The picture images placed on the clipboard by dLSoft's Active Barcode Control's CopyImage method are ANISOTROPIC metafiles. This means that they can be resized within applications (usually by dragging a corner).

While the barcode bars can be resized over very wide ranges, any text included within the image may not resize as expected. In general changing the height of the image by resizing within another application will change the fontsize used to render the text. Changing the width of the image within another application may cause the position of any text under the barcode to change.

The use of TrueType fonts is recommended to prevent unusual effects caused by resizing of text. Furthermore, the use of Enhanced Metafiles has the advantage of producing images in which the fonts scale more smoothly than they do in standard metafiles.

The CopyImage method produces both standard metafile and enhanced metafile pictures on the clipboard. In most case an application that is to receive the picture by pasting will choose the most appropriate picture.

The SaveImage method (when used with a wmf file extension) produces a standard metafile image.
