ilmenit Posted March 26 Share Posted March 26 Thanks to @Sheddy I have a working build environment for Rasta Converter on a new Visual Studio. This allowed me to merge and test the pull requests that were added by the others. The binary build Beta8 done by Sheddy here is the one to use now, the fixes are very good. Having some free time I'll make an official release to download from Github directly. Now I'm trying to understand the highly optimized code introduced by @phaeron with the multi-threading and caching that he added. While the code is of good quality, it's lacking the general comments about concepts used. Also I did not program in C++ for more than 10 years now and never used it for multi-threading so the task is not easy. I have some ideas to check and implement, but first I need to do more code cleanup to make it easier to work with the code in the future. 3 5 Quote Link to comment Share on other sites More sharing options...

While going through some old folders (and trying to fix an annoying issue with Rasta GUI), I came across a beta 7 ZIP, which had extended feature support (and were labelled as "fast builds"). Do you know if these changes have been merged in? The files in questions were titled "RastaConverterBeta7.icl17.SSE2.exe", and "RastaConverterBeta7.icl17.AVX512.exe". I do not have the source, only the exes. Quote Link to comment Share on other sites More sharing options...

I do not have the source, only the exes. they look familiar. I remember sharing those quite a few years ago now. I had got a trial version of the Intel Compiler to try learning something. That didn't work out, but I played with various processor options and Profile Guided Optimization for RastaConverter. There weren't any changes over beta7, but the compiler just did an outstanding optimization for speed on the code. The Intel compiler isn't the same anymore (but is free) and I can't get Profile Guided Optimization to work with RastaConverter and Visual Studio anymore. But it has been compiled with the best settings I could find for speed. 1 Quote Link to comment Share on other sites More sharing options...

That would pop! The way to do this is in pre-processing: produce two (or more) output.png-dst.png images with different types of (or no) dithering then combine the output.png-dst.png images into a single input image with the right kind of dithering in the places you want them and finally run Rasta with that as input and no dithering or other tweaks. I did this in my recent Stonehenge image: the sky below the clouds has knoll dithering strength 3 and the clouds and foreground low strength jarvis dithering.

A question- although it seems to be for a PAL palette, the proportions of this image and many of your other recent ones seem slightly vertically flattened- see for example the very obviously elliptical moon in this one- and the proportions look more 'normal' on an NTSC display where the almost square but very slightly vertically flattened PAL pixels are instead noticeably vertically stretched. Is this because of the kit you are displaying images on? Or is it a deliberate compositional thing to vertically squeeze images into 240 vertical pixels? 1 Quote Link to comment Share on other sites More sharing options...

I have been using Irfan_View 64 for windows for color count and to resize the image when I enter 320 for the width it never sets the hieght to 240 it's always off by a few. Sometimes I try to get a better ratio by making a clip of the image in a 4:3 ration this seems to work better like in this Image of "Pink Roses" . Any ideas are greatly appreciated.

You use this technique a lot. Oh. I did not get it. Now I understand you did that on purpose. I thought you just used very low quality source images, overexposed and noisy. But my observations are not valid I still need to see Rasta Converter pictures on a real CRT... I'm planing to visit a local 8 bit computers museum... There are at least two in my area... 1 Quote Link to comment Share on other sites More sharing options...
