Notes on Metafiles

The picture images placed on the clipboard by dBarcode 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.

To overcome text size problems caused by resizing metafile images choose an alternative fontsize within dBarcode. The use of TrueType fonts is recommended to prevent unusual effects caused by resizing of text.

The 32 bit version of the DLL can also produce Enhanced metafile pictures using calls to BarCodemx.
