SVG thumbnail renderer by Tyrannicodin · Pull Request #442 · TagStudioDev/TagStudio

Tyrannicodin · 2024-09-04T02:41:39Z

Adds an SVG renderer for thumbnails using Qt's QSvgRenderer that writes to a QImage that is written onto a QBuffer that PIL can then read as an image. However, it does have an issue that I have been unable to resolve: Sometimes thumbnails seem to write over each other or otherwise be corrupted (no affect on the actual files though). I think it's due to the QPainter painting in a thread, but I'm not sure.
You can see an example of this problem below:

@CyanVoxel I wonder if a future change would make sense, add a context manager so that it handles the buildup and teardown of thumbnails.

…#472) * fix(PreviewPanel): Use birthtime for creation time st_ctime does not provide accurate creation time on MacOS, and as of Python 3.12 is deprecated for Windows. On these two platforms use st_birthtime, but fall back to st_ctime on linux. * mypy errors

* fix(ThumbRenderer): Use audio icon when no ffmpeg When ffmpeg is missing, Popen raises a FileNotFound error. This would be caught as an Unlinked file and use the broken file icon. The exception is now caught and a more appropriate exception is raised in its place. * ruff formatting

The cutoff for how many files get sorted also changes to 150,000.

* fix(QtDriver): Retain filter on directory refresh * ruff formatting

* feat: increase file scanning performance * fix: correct typo in comment * refactor: use `continue` in place of nested `ifs`

nice work, but as always - when adding a new feature, please add a test.

For this one having some sample .svg image alongside the test, and then compare the output via syrupy that it really provides the expected output. I made a similar test in some other project, so it could look something like this:

from syrupy.extensions.image import PNGImageSnapshotExtension


def test_svg_to_png(snapshot):
    file_path = Path(__file__).parent / "fixtures" / "sample.svg"

    png_image = ThumbRenderer(...)._image_vector_thumb(file_path, 600)
    assert png_image.read() == snapshot(extension_class=PNGImageSnapshotExtension)

also what's the git branch thumbnails? Wouldnt be better to aim this either to the Alpha-9.4 or main?

+        image: QImage = QImage(size, size, QImage.Format.Format_ARGB32)
+        image.fill("#00000000")


this would make it a bit more readable:

Suggested change

image.fill("#00000000")

image.fill(Qt.transparent)

Suggested change

I'm moved this PR from the deprecated thumbnails branch to Alpha-v9.4, which is the branch that thumbnails was eventually merged into. However the v9.4.x releases are now feature frozen and are now solely reserved for bugfixes. This means that after the changes from thumbnails are ported to main that I'll once again be moving the target for this PR over to there as a v9.5 feature.

Sorry for the disruption, and thank you for your patience.
