Hi @Rebecca , @acc4 , the problem of ringing (Moire effect) is tricky to deal with, however it’s possible to lessen this effect by smoothing out the image.
As the image is sampled across in order to be rendered with the desired transformation, the samples may fall at a place where the halftone dot is located (black) and then in an empty area (white), which causes these extreme differences in value and the ringing patterns at some zoom levels.
If the adjacent samples are similar (the difference is less extreme), then the effect will be less noticeable. One example of “smoothing” the input data is the use of mip maps in texturing. Blurring the image could also work, probably.
I attempted below to quickly hack together a crude mipmapping in BeeRef, and got this result with one of the images (right side is the hacked version):
So yeah, I think this is doable, but will require some experimentation, probably with blurring as the ringing can happen sooner than the image is scaled to 50%. Also, for that reason it would have to be an option that you can toggle, because for normal color images the result will be better (and more performant) with the current method.
PS. I somehow had this test image on my disk, but I have no idea where I got it from originally
I’m not sure because I just downloaded it from google, but I believe it’s Takeda Hiromitsu by the looks of it. Do I have to specify it when I bring example images in the threads?
I searched for this pic now for ~20 minutes using all reverse image search engines I know - without success. Either this picture/manga is heavily censored for whatever else is shown there, that we can not see, or it is something super-seldom, I guess. But for the censored theory speaks more or less nothing, because most of the pictures that were shown “as similar” are rough adult material of the most evil kind.
I’ve been using the Appimage since it was released, and it works great on my system, so thanks for that! Overall I really appreciate the program and you’re work on it.
One thing I ran into that I don’t think is a bug but more a limitation: I was trying to copy/paste a couple images from one scene into another, but it will only grab one image. Though it seems to cut/copy and paste as expected within the same scene.
