I would like to use VCL.Skia.TSkSvg to render an SVG, and then copy the resulting bitmap to another control, for example a TImage. I though that might be possible using TSkSvg's Canvas, but that's protected, so presumably not the way to do it. I noticed that FMX.Skia.TSkSvg has a (inherited) PaintTo method, but the VCL version does not. So what is the correct approach? Thanks! For bonus points -- is it possible to perform the above with the TSkSvg control not visible on the Form?

I appreciate your answers, but I'm still not completely understanding how to make this work... A couple of followup questions below: Are you referring to the Rendering SVG example? If so, I'm afraid that example is too incomplete to show how it relates to my task, which is essentially "input an SVG file, render it to a bitmap or canvas." In that example, it's not clear to me: where "ACanvas" comes what is the role of the procedure parameter in the SkiaDraw procedure. I infer that it takes part in rendering the SVG. But under what circumstances does SkiaDraw invoke it? Why so convoluted? I didn't find any doc on SkiaDoc,, so if there is doc for that procedure it might shed some light. For VCL: function SkImageToBitmap(const AImage: ISkImage): TBitmap; Where do I get the ISkImage from? Thanks all!

In most products there's a Check for Updates function on the Help menu, but not in the Delphi 12 IDE. docwiki search finds this page "Check for Updates https://docwiki.embarcadero.com/RADStudio/Sydney/en/Check_for_Updates, last updated in 2015. But I can find no such Check for Updates Start menu item, link or function inside the IDE, in D12, (nor in D10.4 that this page supposedly pertains to). One could check the Release Notes at http://docwiki.embarcadero.com/RADStudio/Athens/en/Release_Notes ... except that page has loads of info about installation, but no actual release notes. Sigh. So how the heck do you check if your IDE is up to date?

... well actually, visiting my account, it turns out that there is another Patch 1, this for 12.1, released 2024-04-18. Though presumably it makes more sense to install that via Getit, which I'm assuming will offer it once 12.1 is installed? We will see. Your point is valid of course... for a customer with 12.0 installed, there is one patch available, called Patch 1. But that was not the last patch released, as we have this Patch 1 for 12.1. Anyhow, now I'm stalled because it's not clear whether I can just install 12.1 over 12.0, or have to uninstall 12.0 first. I am skeptical that in 2024 an uninstall is required, but at https://docwiki.embarcadero.com/RADStudio/Athens/en/Installation there's this obtuse note: So, this appears to say you do have to uninstall. What happens if you do not? Why can't the installer just take care of this? And does that require uninstalling the 3rd party components as well? (Not the topic I originally posted... but frustrating that a ".1" update is not just a one-click process.)

Well, I've been diligently looking in Getit under Updates, and after Patch 1, nothing more appeared. I have only just today realized that Patch 1 is apparently not the same as 12.1, but rather 12.1 is called Release 1. And that never appeared in Getit, and so despite following the recommended procedure to determine if Delphi is up-to-date, apparently it is now 3 months behind. This is just stupid. I don't see why Delphi can't have a plain and simple "Check for update" function that covers any and all new versions of the software.

Hmm, OK I guess. For some reason, when I previously tried the Updates filter with Category All, it returned nothing. I see your screen cap shows Patches and Hotfixes, and that does return a result, so thanks for that. Problem is, GetIt muddles together 100's of offerings from multiple vendors, and the filters are ambiguous, so it's either hard to see the forest for the trees, or if you get rid of the trees (or is it the forest?) there's nothing left and hard to tell the meaning of "No result". I had also tried using the Search box set to "Embarcadero", but that only finds items that mention that name in the description, and doesn't find any items whose vendor is Embarcadero. I tentatively concluded that perhaps updates to RAD Studio were listed under some other vendor name. It wasn't clear what other term I could search for to bring up possible updates. Actually using "update" fetched two items that were irrelevant. I was hoping to find a feature that provides a positive statement "your installation of the IDE is at the latest version". The current "no search results" fails to distinguish between "your installation is up-to-date" and "you didn't guess the right filter and search terms". Anyhow, thanks for your help.

Thanks for your reply. Your suggestion sound plausible, but how, exactly? Tools > Getit Package Manager gets me the Getit Package Manager window. Then what?

The documentation for Vcl.Imaging.pngimage.TPngImage (http://docwiki.embarcadero.com/Libraries/Athens/en/Vcl.Imaging.pngimage.TPngImage) says: Say what?!? First it says to use TPngImage, then is says you don't need to use it. Then it goes on to say that if you add pngimage to the uses clause, something helpful happens, but doesn't say what. I'd appreciate if someone could spell out what is this favored method of using TPngImage without actually using it.

Thanks for your rapid response! This seems like the key information. The docs for TPicture are also a little unhelpful: So does this apparatus expect us to first set the Graphic property to the desired type of TGraphic, and then perform operations like LoadFromFile? The description makes it sound like this causes LoadFromFile to convert from the file's type of image data to the type of image data you've preset in Graphic. Or is it OK starting with nothing set for Graphic, and then just calling LoadFromFile creates the object that Graphic points to, of a type that matches the input image data? And are the Bitmap, Icon, Metafile, and WICImage properties pointers to separate actual objects? Or are they just more-specifically typed pointers to the same object that Graphic points to (ie: at most one would be valid). What happens if the graphic type is not one of the default ones, as with TPNGImage and TJPEGImage? Thanks for any further clues on how to work with this apparatus rather than against it, or via random flounder :-).

On Quality Central I was hoping to look up an issue I filed some time ago. But I got these messages: Query: reporter = currentUser() ORDER BY createdDate DESC Error: Field 'reporter' does not exist or you do not have permission to view it. This appears to be the underlying issue database saying that it can't find any records because it can't apply the WHERE clause. If the site offers the Reported by Me function, and can't execute it, that's a bug, right? I also could not figure out how to submit a bug about QC to QC.

Yes, fair enough. It's not actually labeled as Quality Portal on its pages, but I see it's referred to as that elsewhere.

Hmmm, OK, never mind. Apparently logging out and logging back in fixed the problem.

Does the IDE editor Error Insight (red squiggles) work properly now with inline variable declarations? In 10.3.something, not only did it not work, but it seemed to block Error Insight from analyzing the rest of the file.
