Bitmap images

Unlike metafiles, bitmaps maintain the resolution with which they were created, so that although a bitmap image may be resized at will, the individual dots of the bitmap also get resized. When dBarcode saves a bitmap image it does so with the resolution specified by the iPixelGain property – which is the value specified as the Target resolution in the Graphics options dialog.

The user is recommended to use a target resolution equal to the resolution of the intended printer. ALL barcode images should be tested in their final form before extensive print runs are undertaken.

Note that when using OLE automation to save or copy bitmap images, the transparent property must be 1 (or transparent background not checked) - otherwise the entire image will be black.
