Raster Images: Need to Preserve Proportions

[tajmone]

I've center-aligned all images in the book now, assign to them some arbitrary proportional sizes for the moment being.

We currently have for the raster images the same problem we had before with the SVG diagrams: i.e. that some images belonging to a set of related images (screenshots, directory trees representations, etc.) have different image widths.

We should identify and classify all the images belonging to a same set, and work out a why to re-create them all using the same width as the largest image in the set, so that when we assign them proportional sizes (e.g. scaledwidth="90%",width="90%") these measures result in images of the same set having consistent proportions.

We also need to bear in mind that:

• Some images might require translation of their text (see Translating Commits, Files and Folders Names #1).
• Some screenshot could re-generated by us — but only if the same app/website is still available and we can recreate the same context shown in the screenshot.
• Some images might be worth recreating in SVG (see Convert Dir-Tree Images to SVG #16).

In any case, right now we need to:

• Catalogue how many groups of related images exist.
  • Collect links to all their member images.

then we'll be able to come up with some strategy for each images group.
