When exporting vector objects from CorelDRAW X4, using the EPS filter, and then opening the EPS with a bitmap editor such as PHOTO-PAINT, one pixel will be added to the document's size.
1. Enable 'Floating point numbers' on the Advanced tab in the EPS Export dialog.
2. In CorelDRAW, set the page size to match the size of your objects and then export.
If the page size is bigger than the objects, one pixel will be added when the EPS is opened with a bitmap editor.
Import to a vector based program (keeping vector objects as vectors) is not affected by this.
