The attached sMath file is an attempt to add "current page" background images. One image per page. It work find for the first two pages, but the third one get skipped and the image appeared on the fourth page.

dc dc buck converter.sm (736kb) downloaded 42 time(s).
Basic Calculation of a Buck Converter Power Stage.pdf (203kb) downloaded 34 time(s).

The goal here is to study technical document by overlaying sMath formula, graph and other elements on top of the background images.

Also attached, the original PDF file and the png images for each pages.



Also, it is not obvious how to remove background images, either "All" or "Current page". I couldn't remove the ones in the attached sMath file.

Thank you for your help

Best regards
Guy

I did not know that several background images can be inserted. Actually, I do not know how to do it either. But as workaround you can edit the sm file for correct the position of the image on page 3.

Editing the file worked first try. That is great :-) The sm format is pretty simple, nice to see that.

I found a PDF plugin here : https://ru.smath.info/vi...8e2-06a01fd2b5cc/summary

It does almost what I was trying to do. Except it import all PDF pages as a document image instead of a background image.

Nevertheless, their are still problem with sMath "Background" fonctions. Even after correcting the sm file, I was not able to add an other background image to the file using sMath UI. I did not test yet if I was able to do that by editing the sm file. More to follow...

Hello.

This issue was fixed in one of previous betas: https://en.smath.info/fo...58--11-October-2018.aspx (see "Incorrect pages numbers used in Insert Background dialog fixed for Pages layout mode;" in changelog).

Wow this is a fresh take on checking a calculation book or annotating a paper:

if we could import PDF into SMath as background images (PDF plugin update?), one could just overlay SMath calcs onto existing PDF and the print it to PDF.

Alternatively one could come up with a vb code for script region to do creating a .sm file with all backgrounds in it

This peanut demo is 2.65 kB. You can have as many regions as you wish,
of any colors out of 1677216 possible colors. The background is OK
by the Print Preview, thus will be saved on virtual *.PDF printer.

This background region is not an imported image, neither an image
created by Smath. Thus, every time you save and at the opening of
the document, Smath complains it can find ... because it is not
really created ... just an incomplete fake. So, on the complain
just click OK to stop Smath suffering.

All like this:
1. 2 months ago, I open your *.sm ... all pieces of Smath scattered in ~ 10 pages.
All anywhere in the page ... though nothing to do.
2. Today: open again, realign/space like normal ... toke ~ 15 min
3. Then guess what ,,,
4. Suddenly, Texas stuff appeared dead like stone,
good thing a bit off right of Smath formulas.

COMMENTS:

Generally, there is nothing to do from "Papers" on several counts:
1. Latex is not maths, just just gyzmas ... typical => Dirac ket and bra [bra-ket]
For bra-ket, it toke a grand Physicist like Frank Rioux to make it work in Mathcad.
2. Of the zillions visits web stuff over > 20 years, only 4 where useful maths based.
_ Ristesky Pseudo-inverse
_ Old vintage Mathcad stuff
_ Legendre xi, wi web data table that pasted nice in Smath data vector
_ more recent => Frank Rioux Mathcad *.PDF's

To be of any use in Smath for dead documents [PDF ...] I can see the Capture Technique
i.e: capture pieces, save as images, insert in Smath document.
Then you can move the pieces wherever most convenient in the Samth working regions.

Rbert A. told me one day: Jean, there are many ways to skin a cat
I guess true as well in Smath

Andrey, this tweak just added a whole new horizon of uses of SMath for me, thank you!!!!!

Fresh example of use to annotate with image region (this is neat!)
