If you right click on the image, you can correct the resolution. Perhaps it would be more useful to select from a list of matching page sizes (given the height/width ratio) here. The problem with the user-defined tools such as gimp is that they can change everything, including the resolution, so gscan2pdf relies on the metadata in the image that gimp saves. If you have a .pnm, there is no metadata, and thus the resolution defaults to 72. Of course, it would be possible to make the default user-definable in preferences. Or to add a warning when importing an image for which the resolution is not clear. This might result in a lot of extra warnings. > It would be really cool if saving could also include an optional > normalisation step for the page resolution, such that all pages in > the final PDF have the same granularity. Given that for most people, the page size is more important than the resolution (obviously the two are linked), an implementation for this would be to add a checkbutton to the save menu: * force all pages to be <combobox of page sizes>
