I wish I could figure out proper settings in RastaConverter to remedy this. Limited colour palette on our machine causing this. If I were you, I would try editing the source image - turn down the saturation in the lower half of the image and see if that helps. There's definitely pre-processing that can help with this, but it's all experimenting.

Rybags Posted February 18, 2021 Share Posted February 18, 2021 Usually it's the opposite problem - getting whites instead of colour which is usually fixed by increasing saturation for the entire picture. In this case, desaturating areas that should remain grey should help.

Gunstar Posted February 18, 2021 Share Posted February 18, 2021 (edited) I wouldn't think Rastaconverter for VBXE is necessary. The entire reason we need it for standard Atari's is to allow the maximum colors while working within many restrictions imposed by the hardware. VBXE already has the possibility of displaying millions(?) of colors and direct imports should be possible, as easy as loading a .jpeg and saving it as a .png image or vice-versa. It's only a matter of format and not rebuilding an image from the ground up like Rastaconverter. What VBXE needs is an actual graphic art program so we artistically inclined users can make use of it's graphics. Maybe a G2F "light."

Gunstar Posted February 18, 2021 Share Posted February 18, 2021 As for better color depth art on our Atari 8-bits, there are quite a few decent graphic arts apps that make use of software graphic modes with interlacing and other tricks for better perceived resolution using modes like HIP, TIP, etc. They can display, at different resolutions, anywhere from 16 to thousands of colors, but the issue is flickering. Otherwise the only other option is using G2F on a PC which allows you to create art using many of the same assets and restrictions that Rastaconverter uses to convert images. I've been meaning to get back into real art creation on my Atari myself, using some of these software graphic mode apps. I'd like to see threads like this one for art created by users on Atari's using these new modes and legacy apps like Rambrandt and Technicolor dream. I need to start on my own and maybe get the ball rolling.

Rybags Posted February 18, 2021 Share Posted February 18, 2021 RC for VBXE wouldn't really work. Changing a single palette entry takes 3 x load/store operations for the RGB. Using colourmaps and all 4 palettes and attribute map allows 1024 colours. You could probably do an 8x1 attribute cell size to give an FLI-like mode. Redefining an entire palette probably takes more cycles than it's worth. But even with just the Atari base 256 colours you can cover most needs. Or a custom palette to suit the picture displayed will be even closer.

Yeah - the image viewer I currently am coding does just that - reads an 8bpp BPM file, reads in the palette, then displays the image in 256 colour mode at 320 pixel resolution. It's amazing just how good 320*240@256 colour looks, especially on CRT. Even in 160 pixel resolution, that amount of colour is impressive. 8 Quote Link to comment https://forums.atariage.com/topic/200118-images-generated-by-rastaconverter/page/125/#findComment-4757288 Share on other sites More sharing options...
