transparent background

hello

is there a way for mathcad to export images (of the math regions) with a transparent background?

all i can do is save it as a webpage and get all the math regions as png or jpeg files then copy&paste the to PPT

but those have white background and i can't use most of my templates (for powerpoint).

btw, why ppt? we need to present it in class and a ppt presentation is required.

another question:

is it possible that mathcad show like this?

x:=1

y:=x+1

y=(1)+1=2

can mathcad show the substituted values?

it is easier to understand solutions this way especially when working with very long equations..

thanks.

btw, still no over bar and dots in mathcad variables?

Not completely true. You can have dots, asterisks and other special symbols as variable by pressing ctrl, shift and k after a variable.

There was a thread the other week about the overbarred symbol.

Have a look at the attached worksheet. Keep the font either Times New Roman or Arial and it looks OK.

thanks.

i didn't encounter that explicit "function" in my reference book (eng'g with mathcad)..

a newbie btw..

many thanks!

-------------

also, attached is my another problem..

i know that mathcad computes T1 in kelvin,

but, can it show that T1 (in rankine or kelvin) in the explicit evaluation?

i'm encountering errors when i declare T1:=40degF = 499.67R

yet making T1:=40degF (given in the problem statement that's why i declare it as such) clears the error but

it shows T1 in degF (in the explicit,rpc,T1,k) which is partially wrong since the equation needs absolute temperatures (in K but R will do)

mathcad gives the right answer, T2s=944.508R, but a misleading explicit solution..

is there anything that i can do?

or am i just stuck in

T1=40degF

T1:=499.67R

Something like below?

Can't you highlight the region and copy that image. At least the background won't be white then.

You can just select regions and paste straight into Microsoft paint you know. Might save you a little time.

still has some white background..

anyway, i figured out yesterday that can just use ms office "set transparent color" (first tried photoshop magic eraser but can't manage the letters like "q,e,d etc)"

thanks

(for the general reader)

The background colour can be set by clicking on a blank (background) area of the worksheet, and then selecting Format>>Colour>>Background..

Unfortunately, at the moment (I'm using V14 M030), you can't set it to "transparent". However it does look like you have a workaround, and being able to set the background colour to a special shade is likely to help some folks.

I also use the View>>Regions options a lot to identify where my regions are (and by zooming to 25% you can see left-over stray off-screen regions the create print problems)

Finally, if you press control before clicking on a region it will do a dotted line select, which is what you want for pasting direct into Word or Powerpoint - Don't forget to use Paste Special, otherwise the whole worksheet gets pasted as an OLE and you give away all your IPR !

- and if you receive a Word or Powerpoint with a Mathcad region or graph you shouldn't be double clicking to see if it is active and then scrolling around it... <shocked>

Hi,

I usually copy at least 2 regions at the same time and then paste that into any office application. I use a grey background in Mathcad, but that doesn't show in Office, so it's transparent enough I guess. Every region pasted in the office application appears embedded in a container that tries to keep the object at a specific (page) location. In the office application I can cut the region contents out of that container, paste it elsewhere and delete the container. Then (in MsWord or Outlook) the region moves with text rather than trying to stick to a location.

The trouble when copying/pasting only one region is that I get a different object into office, one that takes substantially more time paste: it might be the complete Mathcad worksheet is transferred with a view/window on just the part that I tried to copy/paste. If I need to transfer only one region, I still copy/paste two, and subsequently delete the superfluous one...

Hope this helps.
