Talk:ZX Spectrum graphic modes

From Wikipedia, the free encyclopedia

This information needs to be reviewed by someone who knows the ZX demo scene or has used any of these modes. I myself only have access to some image converters and emulators, and couldn't get much more information than what's here.

It would be good to sort out the proper names and machines on which they are avaliable as software or hardware supported modes.

Also, a list of graphic editors for each mode would be nice, along with some software that showcases its use. --Ricnun 15:55, 26 July 2006 (UTC)

[edit] Epilepsy?

I'm a bit worried about Image:Parrot rgb3.gif. I think it could give someone a fit, so a slower version would be better -- maybe with a link to the existing version, together with a warning? --StuartBrady (Talk) 22:30, 3 August 2006 (UTC)

• I've replaced both of the flickering images with links and warnings. The W3C's guidelines on this are available here.--Fastfission 14:45, 4 August 2006 (UTC)

• Good, looks fine to me. This "new" display modes do flicker a lot, even on a TV, so the GIFs really simulate the effect (50Hz flicker). I think a good solution is really to just keep the links. Slower gifs will not simulate the effect and still flicker a lot. This way people can see the simulated effect if they can and healht issues are prevented. Since I created and put the images here on the first place, I apologise for some possible inconvenience.

Sorry, I wasn't clear — the idea of using a slower version wasn't to simulate the effect, only to illustrate how the effect works. I should really have said "one or two frames per second". --StuartBrady (Talk) 19:45, 4 August 2006 (UTC)

[edit] Shock Megademo

User:Pak21 removed this sentence, citing Shock Megademo as a counter-example:

However, the Spectrum's processor is not fast enough to write to an entire row of attribute bytes in one scanline, so 8x1 attributes can only be achieved over half of the screen width.

Shock Megademo does not utilise 8x1 attributes. It uses 8x2 attributes on top of alternating paper and ink lines to achieve a different colour on each line; one colour per line equals two colours per 8x2 cell. Don't know if it's worth mentioning this particular example in the paragraph about 8x2... Slovakia 10:31, 28 February 2007 (UTC)

[edit] About the color palette section and the size of the thumbnails

Hello. I am the original writer of the section Color palette in the List of palettes article, ZX Spectrum section. I saw you have copy&pasted the section literally. I think that wikipedians must not to "copy-paste" between us! One of two: or the technical details must keep in this page and the color table keep in the palettes article with a link to the yours, or you should to put a simple paragraph (with your image, it's OK) and a link to the ZX Spectrum section of the "List of palettes" article.

Also, I think that the size you have put the sample thumbnails blurs the images (at least, in my PC) and the original effect is lost. A casual reader (and even an proffesional) will not note any difference between them. I think it's better to keep them at their original 256-width size.Ricardo Cancho Niemietz 20:05, 6 March 2007 (UTC)

I made the copy. Yes, it's a duplication and for me just some details and a link the Spectrum section on the palettes article is a good solution. Just like on other articles were you have "See main article". So that's fine for me.

As for the image size, good point. I formated the article for good layout out of experience. If the images are larger, someone will just edit and change their size. I've see this happen and really I don't have to time do keep reverting edits :-) Let me see if I can format this with 100% images and a good layout. Thanks for your input, I'll see to it when I have time if no one else does it first. Also, congratulations for the good job on the pallettes article ;-)Ricnun 00:31, 7 March 2007 (UTC)
