--- Comment #6 from Philippe Verdy <verd...@wanadoo.fr> ---
REOPEN THIS RFE: the subject was extremedly clear (the rest was a rational for
the need) because we need it for CORRECT scaling of inline images (used within
paragraphs of text) for correct alignment and correct readability.
- (1) supporting max-width= and max-height= parameters in [[Image:]] or
[[File:]], with sizes given in "em" and not necessarily in pixels. This item is
also needed for proper internationlization where text cannot be used and an
image is needed.
- (2) supporting another range of scaling values for the image sets (currently:
1x, 1.5x, 2x) with a parameter "scales=", to allow changing this set to support
other values lower than 1x (notably 0.5x and 0.75x), or even "native" (only
works with SVG images) in order to allow cleaner reductions by the browser,
instead of growths (used by browsers whose "logical pixel" resolution is lower
than the effective display resolution, notably on smartphones (this grately
impoves the readability and sharpness of images. Habing additional values "0.5x
and 0.75x" would also allow cleaner client-side reductions of sizes constrained
by max-width and/or max-height. This item is also needed for
readability/accessibility (including the support of custom zoom levels in
browsers, and adaptation to small screen sizes and screens with very high
resolutions)
item (3) was a follow-on. Item (1) being the MOST important one.
Both are within the support of parameters for [[Image:]] or [[File:]] and how
they are parsed and generate the suitable HTML/CSS code (the related support
for the MediaViewer, only when clicking on the image to view it outside its
inline use, is unrelated)
Without explaining the rationale, you would simply have not understood the need
for it.
If you're still not convinced try navigating pages containing inline images
(most often, small icons such as country flags, or small SVG images needed to
replace text when it does not work to show an appropriate representative glyph,
for example with character variants) with various sizes of displays an with
accessibity zoom enabled (not everyone uses the default 100% zoom especially
with small screens and on displays with very high resolution such as
smartphones and tablets: in almost all cases these default zoom levels can ONLY
be used by the youngest people without any visual problem. Most people about
40yo need to increase the text. But online icons DO NOT scale properly, or are
simply UNREADABLE.
@Andre I DID have provided the detgails several times. Sorry if you don't want
to read them.
