Center attribute, Background Image property
Use the Center attribute of the Background Image (form) property either to center the image or to tile a background image on a form.
When set to True, this attribute causes the image to be centered on the form.
Note: On Report type forms, If you use an oversized image and
set this attribute to True, then the image is cut off
on the edges of the page.
When set to False, this attribute causes the image to be tiled on the form.
Note: On Report type forms, if this attribute is set to
False, then the image is stretched to fill the
form. If you use an oversized image and set this attribute to False, then the image is scaled to fit on the page.
