SVG support
Hi all, Using Dev Cl #6508 RISC OS 5.28 - For some reason Netsurf renders SVGs scaled by a factor of 70%ish in the Y direction. Or, I suppose, 140%ish in the X direction. * For example, go to www.free-svg.org choose an SVG and click "Download SVG" to display it in the Netsurf window. - Resizing the browser window re-renders the SVG over the top of the old one - is it possible to render at 100% in both X and Y directions and if possible to clear the page before replotting the graphic? - And incidentally it might be nice to launch a browser window on double clicking a SVG file. Can one of you clever folks write an Obey file?

I didn't look in detail after I saw "width:1270px;". If it contains such fixed widths and if centred in a narrower window it would extend too far left and right offscreen. Widening the NetSurf window brings it into view. If the window is already as wide as your monitor, reducing the page to 80% zoom would probably bring it on screen. -- Tim Hill Find an event to attend at: http://timil.com/riscos/calendar/ Mimemap and other stuff: http://timil.com/riscos/

It cannot be a negative left-margin as negative values aren't allowed. However - might Metsurf be calculating the margin and ending up with a negative result? -- Richard Torrens. http://www.Torrens.org for genealogy, natural history, wild food, walks, cats and more!

It was pointed out recently that the SVGs of QR codes, created by the QrCode app by calling out to https://api.qrserver.com, render completely black. They contain a line ; deleting this line causes them to be rendered correctly by NetSurf. Dave

How far has SVG rendering got? sVGs are not common yet, but I met a page with some prsent, which don't display properly: https://www.electronics-notes.com/articles/antennas-propagation/dipole-antenna/folded-dipole.php It's also curious tha the text is truncated on the left margin as if CSS left-margin has a negative value. -- Richard Torrens. http://www.Torrens.org for genealogy, natural history, wild food, walks, cats and more!

Perhaps use a rectangle within a rectangle and background colours to create the same effect as a thick line? Turns out that using styles in the svg file does work. The one on the left is two rectangles, the pink one is a thick line.

SVG image support on Netsurf 4088.
Another minor problem with Netsurf: Thick lines on a vector image saved as a SVG file are displayed by Netsurf as lines of probably zero thickness, around a pixel wide. I have put a thick lined square here: <http://powys.org/Temp/thick_lines.html> The Mac Safari browser gets the line thickness right.

Incorrect rendering of SVG files
Hello! As long as the support of SVG on GTK is marked as complete I think the result I'm seeing is a bug. Consider the following SVG file: http://www.w3.org/2000/svg; width="32" height="32"> The image above is rendered as two rectangles side-by-side. On red and another one blue while it appears all red in any other image viewer, image editor or web browser. See the screenshot at: http://ogg.ge/netsurf.png I'm using NetSurf 3.4 on Debian Jessie GNU/Linux. I will happily share any other technical details if needed. Thanks.

Re: SVG rendering - impressive start!
In a dim and distant universe [EMAIL PROTECTED], Michael Drake [EMAIL PROTECTED] enlightened us thusly: As Rob said, if you think NetSurf gets something wrong, report it. Righto. Done. I was (perhaps erroneously) assuming that the SVG support was an unsupported experimental 'bonus' which wasn't fully working yet anyway. The drawfile URL appears to be broken: http://ccdb.cropcircleresearch.com/cc-draw/uk2007aa.drw Odd. Not sure how that happened - but I've now uploaded it so it's now there. Incidentally, if you now go back to the link I gave originally (to the SVG version) and then click the 'draw' format at the bottom of the page, NetSurf now crashes completely. I'll reboot my machine and make sure I've got the latest NetSurf and then I'll report as a bug if it still does it.
SVG rendering - impressive start!
From the Libsvgtiny page, in teeny tiny text I spotted http://croczilla.com/svg/samples/tiger/tiger.svg Followed the link, and ... that's really quite impressive. I tried exporting an ArtWorks file of my own in SVG format and found you haven't done transparency yet, but even so, my hat is off to you gents for your work so far. Now, ArtWorks' SVG expert does have quite a lot of customisable settings. Would you care to comment on the optimum export settings to use, or is it going to remain a question of trial and error for the foreseeable future? Thanks -- Simon Smith The idea of an uncrackable digital rights management (DRM) scheme is fundamentally flawed. Encryption is about A sending information to B while ensuring that C cannot read it. In DRM, B and C are the same person.

Just to qualify that -- it's aiming at SVG Tiny 1.1 as specified at http://www.w3.org/TR/SVGMobile/ There's a Tiny profile of SVG 1.2 in Candidate Recommendation (http://www.w3.org/TR/SVGMobile12/) that adds significantly more features. This is not currently being considered for implementation in libsvgtiny. John.
