The problem with Dwarf Fortress right now is we can only pick one texture filter for both zooming in and zooming out.
Alike to JASC (former manufacturer of PaintShop Pro) suggested - Bilinear for downsampling and Bicubic for upscaling (I am not sure what corel have made of that once great program right now)...
And I am still puzzled why we have so many more algorithms for resizing in VideoApplications (especially MeGUI) compared to pure image apps (puzzled because the scaling takes place in each picture and I am not sure what exactly is different, or why they are not used in classic raster apps), ie.: Lanczos, Point, Spline(, etc.)... And furthermore why the video apps let us choose in bicubic and others for a strength value (weighting parameter) but in pure raster apps its always 1 (not sure if the weighting happens over frames - but as it is named strength I would say just in single frame)....
That is a major conflict in me (with me) whenever I encode/capture my old VHS tapes or not secured DVDs and somehow my used RemoteSensing/Raster knowledge is questioned by Analog2Digital/Interlace/Film/Pulldown/etc. :insane: and thereafter the simply question wich method to use in resizing (well, actually that was the cause for me to go/stay anamorphic in the encodes)... sigh (but that simply is no answer to my questions that occurred in the process)
So far as we can just zoom out my prefered method would be (only using the classic three (nearest/bilinear/bicubic) according to JASC and not counting RemoteSensing Context) bilinear - but as my GFX knowledge is besides nowadays GeoReferenced Images just good old DPaint and Amiga IFF Pixel Art, I really can't comment on the methods of handling resizing but somehow still can on the handling of methods to resize images :yikes::insane:
Oops... overlooked that one:
arclance: nearest is a default by me since I played the pre 2010 Versions on my laptop as
that whatsoever certified FireGL Pro on the build in TFT produced ugly results with bilinear
(not on an external CRT) - besides less colours (yes, our eyes may not be able to differ
them, but that what is not visible but diplayed makes it smooth and for some spectral
analysis 1024 is better then 256 per channel) on TFTs that is still one of my arguments to
stick to CRTs (not that this Laptop GFX Adapter is able of 48bit+, just a general thought
about the Matrox Cards (CAD/RemoteSensing/GIS Area) I really would like to buy)
