Re: SVG add object question

2017-10-22 Thread Keith Culotta via 4D_Tech 
A nice solution!  Just to be sure, it was to use ".svg" rather than "svg"?

$svgPictureRef:=SVG_New_embedded_image 
($svgCopyrightLayer_Ref;$interPicture;5;0;“.svg“)
rather than
$svgPictureRef:=SVG_New_embedded_image 
($svgCopyrightLayer_Ref;$interPicture;5;0;“svg“)


As displayed in the web page:
Next I tried the defined codec-option „svg“
$svgPictureRef:=SVG_New_embedded_image 
($svgCopyrightLayer_Ref;$interPicture;5;0;“svg“)  // appears the same
to no avail.

Finally I checked my manual of the source. Actually codec means extension, ergo 
„.svg“. This line of code
$svgPictureRef:=SVG_New_embedded_image 
($svgCopyrightLayer_Ref;$interPicture;5;0;“svg“)  // appears the same
delivers what I was looking for: 4D renders SVG inside SVG perfectly well.

Re: SVG add object question

2017-10-22 Thread Kirk Brooks via 4D_Tech 
Hi Keith,
Huh - that sounds like the problem I'm having. Plus I was thinking the
added document ref would remain valid - like adding an object to a c-obj.
That's not the way it works I know now. Makes sense to get the elements and
just add those. That's more or less what I would up doing anyway.

Thanks for the insight.

I think I recall a discussion a while back about SVG_Add_object not working 
well when the object being added was another svg document.
Two svg docs can be "combined" using SVG_ELEMENTS_TO_ARRAYS, and SVG_Add_object 
for each reference in the doc being added.
This technique doesn't produce a complete merge if doc2 has structures, like 
patterns, that the elements of doc2 depend on.

Kirk, I do not have answer as I do not use SVG component to manipulate SVG,
I handle them with XML commands. Note that SVG objects are just XML trees
and can be manipulated with XML  commands. For example, you can use command
DOM EXPORT TO FILE
to export SVG as XML file and explore it in text or XML editor.

In your case, I would guess that $svg is not properly formed as SVG image.

Jim,
No, the file is an SVG document made up of XML. SVG_open_picture is what
you're thinking of.

SVG add object question

2017-10-21 Thread Kirk Brooks via 4D_Tech 
I must be confused about how this works. I have some SVG files I want to
use to create button icons. These are nice, simple, native SVG. I want to
manipulate them using SVG. I can open a file and export it to a pic
variable just fine. But I'm not able to put that object into a new svg.

For example:

$svgImg:=SVG_Open_file ($path+$aDocs{$n})

$svg:=SVG_Copy ($svgImg)
$pic1:=SVG_Export_to_picture ($svg;0)
SVG_CLEAR ($svg)

This works as expected.

$svg:=SVG_New
$newObj:=SVG_Add_object ($svg;$svgImg)
$pic2:=SVG_Export_to_picture ($svg;0)


This doesn't work. $pic2 is blank even though $svg has received the new
object. I can see that by looking at $svg in the viewer.

What am I missing here?
