Image Tests for the Encyclopedie Image Tests for the Encyclopedie Test scans of Plates from the Quarter size Folio reprint edition. I have made adjustments to the brightness and contrast to improve the image by eliminating bleedings from the other side of the page.
TIFFs are much larger.
Folio page of text scanned from the same edition. All image browsers will allow you to crop and zoom into particular details. For text and image, this seems to allow for very high resolution images for details. I have not noticed any significant difference between JPEG and GIF compression, leading us to select JPEG because of superior compression. My preliminary suggestion is that we adopted 256 levels of grey scale, jpeg encoding for all images.
