Original imagem sizes:
width: 17008px
Height: 8504px
Size:413mb
Layers:1
SmartObject: NO

Channels: 4 (RGB,Red,Green,Blue)

Setting of Photoshop to save:
quality: 12
Progressive with 3 scans

Code:

using (PsdImage imageHI = (PsdImage)Image.Load(imagem.OriginalFullPath, new LoadOptions() { BufferSizeHint = 50 }))
{
imageLO.Resize(300, 300);
using (MemoryStream mbStream = new MemoryStream())
{
imageLO.Save(mbStream, new Aspose.PSD.ImageOptions.JpegOptions()
{
Quality = 100,
CompressionType = Aspose.PSD.FileFormats.Jpeg.JpegCompressionMode.Progressive,
JpegLsAllowedLossyError=10
});
resultOfRecord.BinaryLowResolution = mbStream.ToArray();
}
}

It looks like that the issue in the resizing. Please try

imageLO.Resize(300, 300, ResizeType.LanczosResample);

Also, please check this API reference link: RasterImage.Resize | Aspose.PSD for .NET API Reference Resize method has the additional argument “ResizeType”. Default resize type is Nearest Neighbor, you can try any of supported resize types to find the best solution for you Enum ResizeType | Aspose.PSD for .NET API Reference

If my recommendations don’t help, please send me original file that you tried to resize and save. It’s better to use some cloud storage like onedrive, dropbox and etc and share the url via direct messages on forum.

SOLVED!
Tks for quick answer!
I used The Mitchell cubic interpolation method, and get good result, perhaps, but is very slow. I’ll keep it.
