Draw Render in a draw file

For me it has been exercise for the brain, but it might have some practical use. ;-)

Exactly the same with my XP1TrForm…and I might actually make it do things with text now, too.

I should revisit some stuff I did when I was working at the Scottish Schools’ Equipment Research Centre. Distorting drawfiles in various ways to give perspective views – of the original drawfile lying flat, or rolled around a cylinder or a cone. (Text really did have to be converted to path for that.) Quite different sorts of things, like a program to draw gear wheels and screw threads viewed from different angles. These things could be much better than I could do on an A540 in 1991…

Ask one get two,:-)
@Steve
I did a test it works “almost”…
*transform SVG2Draw_Out Draw_out 0.80 0.0 0.0 (-0.80) 0 1460
The Y translation is not correct.
The source drawing is in A5 landscape format, and after transformation I have to change the format to portrait.
The conversion with !XP1TrForm does it correctly.
The value 1460 is the height of an A5 landscape page that I measure with !WimpInfo.
Thanks you both, the corrections of my program are progressing…

it works “almost”

Oops! It falls a bit short, which may be a rounding error, perhaps. I did say in the !ReadMe that I was not happy with the units. ;-(

Anyway, I have followed Clive and gone for millimetres. The revised Transform seems to get it right, but I await your report. There is also a problem with plain Sprites to think about.

I think that’s the point at which I bow out. Even text is really beyond my interest, given the mismatch between RISCOS and TrueType or PostScript fonts. Really my interest in Draw is that I like doing vector graphics in Draw, and being able to fiddle with them in BASIC, but then export them to use on the Mac (as SVG). The converse process interests me far less.

Bonjour,
Busy correcting Svg2Draw, with the simplifications made by your programs.

@Steve, I tested the latest version, it’s OK, nice.
I put a demo version to download with examples and your transformation programs
https://jeanmichelb.riscos.fr/Download/Svg2Draw01.zip
Don’t turn your monitors, use your programs :-)

The modification for the text elements is not done yet and all the Path operators are not corrected.
There is an Xat directory that contains SVG files that were exported by ArtWorks. These do not need to be returned.

For information Svg2Draw uses eXML (from Xat) not included in the zip file.
, as well as mkdrawf, 32bit version, to build Draw scripts.

I recommend the very useful !MkDrawf application, I used it to replace postscript outputs in !PariGP2132 to draw curves.

!MkDrawf, available here:

and for – 1st class honours in Maths —
I use this program to calculate transformation matrix for Svg2Draw.

Sorry my website is not a model of its kind…

Bonjour,
After a lot of improvements and corrections, a new version of !Svg2Draw which uses transformation programs. This allows me to draw and reverse/translate the drawing only when creating the file.
Thanks to Clive and Fred for showing me that I could do it this way and for their code. Very useful cooperation on the Rool Forum.
Svg2Draw (version 0.3) : https://jeanmichelb.riscos.fr/Download/Svg2Draw03.zip
Some examples:

Missing features like transparency/opacity, can be done with !ArtWorks.
Svg2Draw therefore allows the use of SVG files with !ArtWorks, not all….

Just done a few quick test with Svg2Draw and it handled everthing I threw at it,

One area where it beats NetSurf’s SVG to Draw conversions is that yours can handle the SVG files that my QrCode application creates.

Thanks Kevin for testing.

Nice to see your QrCode displayed, Useful for producing a large format version…
If I understood correctly the code is built on the site, as well as the drawing in SVG format.
This is interesting for exchanges between Os.

My app just sends the information to the server with the size and what format is required.

The size is between 25 and 1000 pixels
