With Skia, the resulting view is blurred; with default render and disabled AA / HW acceleration, the view is pixelated. Indeed, as I suspected, we do have a code to down-sample bitmaps: VclMetafileProcessor2D::CreateBufferDevice [1] that checks that the image for effect processing has no greater than 500 000 pixels (which is around 707x707 pixel bitmap). But unexpectedly, this downsampling didn't trigger in this case! The bitmap size is calculated from the passed logical object range, which is 14730x15750 units. These units are converted to pixels using OutputDevice::LogicToPixel, and the result is 557x596 pixels. This value is independent on the screen resolution; it seems that VclMetafileProcessor2D uses the object's logical size (which is, for the image with effect, 14.73x15.75 cm = 14730x15750 mm/100 units that are used internally). It is converted using a default 96 PPI resolution, and then that image size is used for effects and rendered back to the metafile, which will be rendered to screen when this slide's turn arrives. Given that e.g. my screen is 1920x1080 pixels, and the image takes almost full height, the bitmap used for the rendering is about two times shorter than needed for a reasonable quality. The question is: how can I get the target resolution at which the metafile is going to be displayed. If I get that, then it could make sense to increase the maximum bitmap size here. OTOH, I couldn't get the problem in edit mode on Windows. This codepath doesn't use VclMetafileProcessor2D, so no downsampling takes place. Could it be that kf5 uses a different rendering codepath, or maybe there's some other way to enable metafile rendering in editing mode? Thorsten, Armin: sorry to bother you, but maybe you have some ideas how to handle this?

https://bugs.documentfoundation.org/show_bug.cgi?id=145157 --- Comment #12 from Mike Kaganski --- (In reply to Rafael Lima from comment #11) > @Mike, what do you think of this issue while applying soft edges. I didn't check the code, but I (seem to) remember there was some pixel count limit, after which we limit the image quality to avoid freezing. This *might* be that. -- You are receiving this mail because: You are the assignee for the bug.

Notice that when I switch from radius 0 to 1 the image gets distorted. When I get back to 0 the image is restored. -- You are receiving this mail because: You are the assignee for the bug.

Thanks for your help with this issue. Indeed in your screenshot there's no visible distortion. So, I upload a screenshot of what I'm seeing. Note that the image in the right is more pixelated. This test was done in KDE using LO 7.3 alpha, but I had the same results in Windows. Can this be related to graphics card maybe? I use Nvidia in both my PCs. -- You are receiving this mail because: You are the assignee for the bug.

This time around I used a polygon-based image. In the first slide I added the original image without any effects. In the second slide I applied the Soft Edges effect.

https://bugs.documentfoundation.org/show_bug.cgi?id=145157 --- Comment #2 from Rafael Lima --- BTW, when exporting as PDF the quality of the images is significantly worsened and pixelated (both with and without the soft edges effect). So I guess the PDF part of my original report has nothing to do with Soft Edges, but rather with general poor image quality export. -- You are receiving this mail because: You are the assignee for the bug.
