Thanks for info: It is already best downsampling options available in FRV.
The problem is: when downsampling from say 1000 pixel-wide image to 898 pixels on screen (zoom ratio 89.8%) each pixel on screen
- either calculated as a mix of adjacent original pixels, resulting into softer image
- or nearest pixel is picked up, resulting in moire and other downsampling artifacts.
FastRawViewer Area resample for zoom ratrios 0.9999 - 0.6 is really a mix of bicubic and Area resize, again to suppress artifacts. Probably we need an option here (mix or not), but slightly resampled images always looks softer than original one.
Toggle zoom key (Z) allows quick zoom to 100% (configurable) and back, probably this helps with issue.
