I don't know how you do it, but if you can convert the hi-res file to a PDF somehow, then FILENAME.pdf should be used for PDF output while FILENAME.png is used for HTML.

Re: Width and Height in @image for Html Output fail
It occurs to me that one requires two image versions:
(1) An image for high-resolution pdf; and (2) Another
image for low resolution image html.
Can we think of only having one command that calls
@image, rather than two (i.e. rather than having @iftex
and @ifhtml)?
For instance,
@image{../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg.png}
For pdf output will use the file
../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg.png
For html output will use
../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg.html.png
Or the like.

Christopher

This is completely wrong, looks like LaTeX or something which you can't
use.
Try
@tex
\global\parskip=3em
@end tex
instead.
Re: Paragraph vertical space
You can use
@vskip 3mm

Paragraph vertical space
Hi,
In the PDF output, I want to augment the minimum vertical space between
paragraph.
I tried without success this naive approach:
@tex
\usepackage{parskip}
\setlength{\parskip}{3em}
@end tex

The problem seems to be with the \xeatspaces macro. This is barfing at
being given an argument beginning with a newline (as the comma is right
before the newline, that is included in the argument). With
@tracingmacros=1:
@floatlabel ->@xeatspaces {
ch10-FileListChangeSet}
@xeatspaces ->@eatspaces
@eatspaces #1->@expandafter @trim@ @expandafter {#1 }
#1<-
ch10-FileListChangeSet
->@par
@trim@ #1->@trim@@ @#1 @ #1 @ @@
Runaway argument?
{
! Paragraph ended before @trim@ was complete.
I tried to give active newline a definition that would make it disappear
in this context, but this didn't work, as you can't make new definitions
in TeX when you are in an expansion-only context.
It's related to a recently reported problem:
https://lists.gnu.org/archive/html/help-texinfo/2020-10/msg1.html
It would ideal if \xeatspaces could be run earlier. I'll think about
this again but may not succeed.
What could perhaps be done is, when the macro has several parameters, to
make ends of lines insignificant. This doesn't conflict with any of the
test cases in texinfo-tex-test.texi; however, you could imagine a use
case for a @macro where this was important, where the arguments are like
@inlinefmt where newlines should be kept in just one of the arguments.
Re: Width and Height in @image for Html Output fail
So what I got to do is reduce the pixel sizes?

Thusly you suggest I have two files, small ones for html. Is that how things are done for web pages?

Re: Error with macro use case where arguments span in several lines
Yeah, the mail agent formatting
Hope it will be right now:
@c Figure with caption
@macro figure{caption,file,width}
@ifnotplaintext
@float Figure,\file\
@center @image{\file\,\width\cm}
@caption{\caption\}
@end float
@end ifnotplaintext
@ifplaintext
@float Figure
@caption{\caption\}
@end float
@end ifplaintext
@iftex
@sp 1
@end iftex
@end macro
