We describe one tool designed to enhance the visualization of chemical structural formulae in E-book readers. When dealing with small formulae, to avoid the pixelation effect with zoomed images, the formula is converted to a vectoral representation and then enlarged. On the opposite, large formulae are split in sub-images by cutting the image in suitable locations attempting to reduce the parts of the formula that are broken. In both cases the formulae are embedded in one ePub document that allows users to browse the chemical structure on most reading devices.
