Issue | Black Pixels along Right Edge with Wonder 3

Topaz Gigapixel Bugs and Issues

I upscaled images to 1500 pixels on the longest side using all three intensities of Wonder 3: low, medium, and high. All three settings exhibit the same problems in several images I upscale. And yes, the input images are free of black borders before upscaling. I’ve attached an example, but all the outputs have the same problem.

That is a bug on some unusual scaling factor (e.g. 1.2x). We will figure it out. Please give a try with some scale factors like 2x first then you can resize it to any kind of resolution.

I use Wonder 3 with 4x and in this case the issue seems to occur when the dimension is not a multiple of 4 pixels.

  • Both width and height are multiples of 4 pixels: No black borders.
  • Width is not a multiple of 4 pixels, Height is a multiple of 4 pixels: Black border on the right.
  • Width is a multiple of 4 pixels, Height is not a multiple of 4 pixels: Black border on the bottom.
  • Both width and height are not multiples of 4 pixels: Black borders on the right and the bottom.
