Package: aptitude-doc-en Version: 0.8.13-1 All of the screenshots are illegible because a width="100%" property is set in each <img> tag, causing them to be stretched and introducing significant aliasing. Resizing the browser window to a smaller size does not help much. Due to the low resolution of the images (484x316) and small size of the text, even minimal scaling causes blurring and aliasing. The text, though small, is completely clear and legible when the images are rendered at their native resolution.
This is the case in the HTML help installed to /usr/share/doc/aptitude/html/en by the aptitude-doc-en package, as well as the online version. Please view for an example: https://www.debian.org/doc/manuals/aptitude/ch01s01s01.en.html I suggest removing the width='100%' property from each of the the <imagedata> tags in the DocBook XML source (/doc/en/aptitude.xml) or adding an img selector in the CSS stylesheet (/doc/aptitude.css) with a width:auto property, which will override the the HTML <img> tags.
