Hi Shawn, > It should also be considered a bug IMO. The only obvious part of the whole disaster that IMO qualifies as a "bug" is the fact, that binding a size ends up in 2 calls - but AFAIK this is not specific to QQuickImage. Maybe one could say, that QQuickImage shouldn't do any updates

Does anyone knows which modules we need to have compiled in order to make svg support work? I depend on a static build of Qt and while I was able to use SVG with the prebuilt Qt, I couldn’t make use of it using my static build. I realised I was missing qtsvg module but even after including it

Xavier, SVG did the trick I just had to add it to resources and pass it to the image element. Looking great now!! :) Thank you all for your help Best, Nuno > On 6 Mar 2018, at 16:50, Xavier Bigand wrote: > > I think that you just have to link the svg

The anti-aliasing only works on edges except for the Super Sampling AA. 2018-03-06 17:49 GMT+01:00 Nuno Santos : > Allan, > > I have tried to enable antialiasing to true but it didn’t made any > difference > > :( > > > On 6 Mar 2018, at 16:47, Allan Sandfeld Jensen

I think that you just have to link the svg module, if I remember correctly, then in QML just use it as source of an Image item. The only think is that you have to fix the size of the item as the sourceSize have no sense here. 2018-03-06 17:47 GMT+01:00 Nuno Santos : > I

Hi, If your sample picture is relevant I can suggest you to convert it as SVG (vectoring it) or using distance field technique. 2018-03-06 17:06 GMT+01:00 Jason H : > Maybe this has something to do with with mipMapping/smooth? It looks like > it's not anti-aliasing? > > *Sent:*

Maybe this has something to do with with mipMapping/smooth? It looks like it's not anti-aliasing?   Sent: Tuesday, March 06, 2018 at 10:50 AM From: "Nuno Santos" To: "Mitch Curtis" Cc: "Qt Project MailingList" Subject:
