I need to browse SVG images from a ZIP folder.

I have tried the ZipBrowser demo in: \Demos\Other\ZipBrowser

It can browse the image files from a ZIP archive if they are normal pixel images, such as PNG.

Unfortunately, it cannot display the SVG images in a ZIP archive.

Is this a general problem, or is there a workaround?

Yes, I mean using native SVG support. This should be working very well in ImageEnView by now.

Is TImageEnFolderMView or ImageEnMView able to display SVG images? If so, I could extract the SVG images from the ZIP archive myself and insert them into ImageEnMView.

UPDATE: TImageEnFolderMView can show SVG images from a folder if Vcl.Skia is added to the uses clause, and Skia is ENABLED in Project Options (in the Project Manager).

UPDATE 2: Heureka! The same applies to the ZIP-BROWSER:



UPDATE 3: It loaded 1,426 (!) SVG files from a ZIP file in less than one second (due to LoadOnDemand):

ImageEnMView1.FillFromZip(
ZipFilename,
ZipPath,
iefAllFiles,
'',
True); // Load on demand

UPDATE 4: I improved the ZIP-BROWSER demo with a Search capability, as 1,426 files need searching:

procedure TForm1.LabeledEditSearchChange(Sender: TObject);
var
  ThisSearchTerm: string;
begin
  ThisSearchTerm := Trim(LabeledEditSearch.Text);
  ImageEnMView1.Filter := '*' + ThisSearchTerm + '*';
end;


The search speed is impressive because it is practically immediate.

SUGGESTION: Please add a simple property (e.g., OleDragAllowed) to TImagenMView that, when set to True, allows dragging an image from ImageEnMView to Windows File Explorer. This would be very helpful. Thank you!

Hi Peter

I'll need to investigate that. I assume you mean using native SVG support, rather than the ImageMagick DLLs?
