Not scanned, straight from the web. The question to Mike is type a Latex y in the book style and check if it does look exactly the same as the Windows unsmoothed italic. It could be that the books style would just be ignored and considered as "simply Windows italic". At 51 threads, no collab had that kind of answer, then ask PTC directly . Maybe they have an interpreter not for public or commercial use. I have been in those styles for many years with my clients, the best text and math styles were the Foxboro technical sheets, their answer to me (and my clients): proprietary ... end of it. They had their own software, with print output of their special proprietary characters a lot more beautiful and easy to read than the only FORTRAN in those years.

Sorry, can't help more w/o work sheet and the intent of it.

yeah I have figured that. Also that mathcad typesets differently to Word, Open Office, Mathematica, Maple -- who all attempt to do it the way that AMS and NIST want it done, and make it easy to do I might add-- because that's the way it is. In all these softwares if you want to do it differently you can, just like it seems that if you want to try and do it correctly in mathcad you can (it seems), sort of anyway. I'm not sure what the point of him posting images of non-typeset stuff and of programs was for, other than red herrings, since it wasn't what I asked about.

But thanks to others who have made sane replies for me.

If you're in the habit of requiring your sheets to look that way, you can save the prototype sheet as a template, and you can use that template for any new sheets that need to look or behave a certain way.

I noticed three distinctions: Italic, Oblique, Slant. The last Mathematica image you have seen is "slant" though in the face option it is called "italic". You can see that clearly comparing with Eden Mathcad "italic" . Some of these links will tell you everything about the actual fonts in the math market. What I have said about the readability and the human eye, others have said the same in different words, a most important factor for the "papers" and eventually work sheets. Also, I mentioned getting informed at PTC for an eventual coding, that makes sense unless some collabs can reply directly ... it makes sense as it seems that lot of these math fonts can be coded in any type characters. Adobe has the ISO but incomplete. The Post Script fonts are probably the one that will make you happy as they are "hinted" ( my expression was "smoothed" )because they are "scalable vector fonts".

My main point (other collabs too) was that Mathcad does not distinguish decorations neither in the variable name or in the argument. Mathcad only recognizes what is executable. If it would be otherwise, the confusion would be total and rendering work sheets not interpretable, also considering as many decorative styles as there would be users.

That's about a start of the "sensitive discussion/help". The next step you may be interested in is the WRI fonts. My understanding is that it will open somewhere in Windows (see the instructions) and from there you can just plug into the FONTS and you will not need the Mathematica package to have them at hand... Do I interpret correctly ? What they don't say either is with what Windows applications they will work, maybe with their math package only, I bet on that ... then you will have to purchase an expensive and specific package surely not ISO ! and probably more confusing than useful as f[x] that if you write ISO f(x) will return a blue page of errors to the inadverted user.

The most recent version of the special Mathematica fonts in PostScript format is available from the following link.

PostScript fonts are outline font specifications developed by Adobe Systems for professional digital typesetting, which uses PostScript file format to encode font information.

By using PostScript (PS) language, the glyphs are described with cubic B�zier curves (as opposed to the quadratic curves of TrueType), and thus a single set of glyphs can be resized through simple mathematical transformations, which can then be sent to a PostScript-ready printer. Because the data of Type 1 is a description of the outline of a glyph and not a raster image, Type 1 fonts are commonly referred to as "outline fonts". For users wanting to preview these typefaces on an electronic display, small versions of a font need extra hints and anti-aliasing to look legible and attractive on screen. This often came in the form of an additional bitmap font of the same typeface, optimized for screen display. Otherwise, in order to preview the Type 1 fonts in typesetting applications, the Adobe Type Manager utility was required.

Font hinting is the use of mathematical instructions to adjust the display of an outline font so that it lines up with a rasterized grid. At small screen sizes, with or without antialiasing, hinting is critical for producing a clear, legible text for human readers. It is also known as instructing.

For the purpose of on-screen text display, font hinting instructs which primary pixels are interpolated to more clearly render a font.

One popular and recognizable form of hinting is found in the TrueType font format, released in 1991 by Apple Computer. Hinting in TrueType invokes tables of font data used to render fonts properly on screen. One aspect of TrueType hinting is grid-fitting, which modifies the height and width of font characters to line up to the set pixel grid of screen display. The open-source FreeType font rendering engine uses an auto-hinter when such hinting data is not present or its use is restricted by a software patent.

Hints are usually created in a font editor during the typeface design process and embedded in the font. A font can be hinted either automatically (through processed algorithms based on the character outlines) or set manually. Most font editors are able to do automatic hinting, and this approach is suitable for many fonts. However, commercial fonts of the highest quality are often manually hinted to provide the sharpest appearance on computer displays. Verdana is one example of a font that contains a large amount of hinting data, much of which was accomplished manually by type engineer Tom Rickner, who also helped develop TrueType.

Mathcad does distinguish between 'decorations' in the sense that the math style name forms part of the variable name.

The xmcd file defines the style at the beginning of the worksheet, eg mathStyle name="User 7" font-family="Tahoma" font-charset="0" font-size="12" font-weight="bold" font-style="italic" underline="false"/>

The xmcd file defines the variables in the region section, eg ml:id xml:space="preserve" font="10">x</ml:id where the "ml:id" bound the variable name and "font=" identifies which math style applies.

In Mathcad 7, the equivalents would be
.CMD DEFINE_FONTSTYLE_NAME fontID=10 name=User^7
{10:x}

Hence validating the assertion that the math style forms part of a variable name.

The main problem with the appearance of italics is due to the limitations of the Mathcad screen render coupled to what, for many, is still a fairly coarse display resolution - it's the 'staggering' of the pixels in the italic lines that creates the problem.

Try looking at the attached worksheet in 150% or 200% zoom - the fonts look much better, although still a little bit jagged (look at the radical sign).

Better yet, print it out - the italics look fine.

Or export it to pdf, Adobe Reader does a better job of smoothing the lines on screen than Mathcad does. Zoom to 100%, 150% and 200% to see the difference.

The attached worksheet also gives the Latex program that generated the text in the 'image' that I used as the basis for the 'Mathcad' content. (note default equation text is italic, \rm = roman and \bf = bold font). A Latex file is 'simply' a means of telling a Latex processor what to draw and is notionally equivalent to postscript or pdf in that sense.

The functional impact on Mathcad by providing Latex output would be about zero.

Thanks for your interest Stuart,

Your Latex coding, codes directly in ORIGINLAB. It codes on a special template as well as on the plotting graphic, but I didn't use for at least 8 years and my use was limited to better displays in the graphic. Back to the WRI fonts, they are those specials characters/symbols particular to Mathematica... their interest as math equation is zero absolute 0 ! The AMSF are free, maybe worth a try for the originator... and my point here is about using them "as Mathcad executable" as far as Mathcad is receptive and if they are smoothed and if they can be coded.

Nothing to add on my part. The originator wanted "Mathcad italic", Mathcad has italic but it does not have italic because the Windows italic fonts are crappy enough to scare flies. As a byside remark, the Mathcad parentheses go by the the Verdana, i.e: for colored brackets define a user7 dunmmy variable Verdana and you will get all the brackets in color, just very distinctive.

I use sometimes Leibnitz font, from an old version of a front end for mathematica, but this font isn't free. Italics appears in 'normal' font, so, greek chars don't appears in italics.

Problem is that no body have installed this font, and there are no option to embed the font into mathcad document.

Alvaro,

Yes, this font is free, how ?

Download the Mathematica free trial version, it will install all their fonts, and these fonts remain in the Windows. The Mathematica fonts were designed by Publicon (one of their subcontract), and at the time I got Publicon, it was free from the web. Same thing with most fonts from other sources than the Mathcd CD.
