Plot Mask Seems Broken For > 256 Colours

Mon, 06 Apr 2020 13:36:47 -0000

Aha! The mode word of these sprites is &301680B5 which means the top bit is set, indicating a wide 8bpp (alpha?) mask rather than the binary mask I would have expected.

If all the mask plotting SWIs do not support alpha masks, like the PRM says for OS_SpriteOp 49, then that would explain why this is broken.

A workaround could be coded to write the mask memory directly but realistically I won’t have time to do that.

It looks now like that might fall under the scope of the bounty after all, as one of the tasks is to add support for alpha masks.

But nobody seems to have told Aldi!

Individual card terminals need to be updated manually, it seems. Presumably this is being rolled out on a store by store basis by the supermarkets. It hadn’t reached Sainsbury’s in West Yorkshire this morning, either.

Other things on the todo list are Wimp task association

Do you mean the ability to resource reservation, like booking a timer for your task’s use (to prevent another task from crashing in and stealing your timer)?

It sounds like anything ending in Stats or Mon would be a misnomer, and the name should end in Utils. Stats and Mon imply measurement only.

I’d vote for CPUPerfUtils.

mainly the ones that are classed as Official music ones that I have tried,

Don’t forget they are going to want to tweak official music videos from time to time in order to protect their interests in YouTube Red, Premium, Special, Music, or whatever they’re calling it this year…
Why would people cough up $10-$12 a month if they could just rip everything outside of the official YouTube app? You still can, mostly, but they aren’t making it easy.

Other stuff seems to be a lot less effected.

But, yes, once in a while signature patches will be required when things get tweaked.

Here’s a tiny bit of diagnostic information.

1. I made a 3 × 3 16M colour sprite with a mask in Paint.
2. I coloured the top row red, middle row green, bottom row blue.
3. I set the middle pixel to transparent and saved the image.

When I open the image in a hex editor, the mask data for the image created in 3. is FFFFFFFF FFFFFFFD FFFFFFFF.

This means 1 word of data has been written for each 3 pixel row of the image.

When I drag the camera tool over the whole image and use it to export the sprite, that sprite file’s mask data is then FFFFFFFF FFFFFFFF FFFFFFFF.

More information to follow…

April 1st the service changed host point to be coming from Google servers, certificates on the servers are issued by Google is one notable change…

Ah ha! That might explain why there’s a certificate error on some video downloads from !Murnong.

I think the there must have been a recent change to YouTube as some videos do not work now that used to, mainly the ones that are classed as Official music ones that I have tried, so I guess an update to YouTubeDL is required.

April 1st the service changed host point to be coming from Google servers, certificates on the servers are issued by Google is one notable change – not that I’ve had to do various changes on the organisational proxy to allow Covid 19 related content or anything….

Other changes were hinted at a whhile back – particularly video formats.

For a woking YTPlay all the other tools (Python, Youtubdl, FFPlay…) must only seen by the filer. Is not necessary to load all.

Hi Raik, thanks for clarifying that as I always assumed they had to be loaded but testing here shows that just seeing the applications works as you suggest.

I think the there must have been a recent change to YouTube as some videos do not work now that used to, mainly the ones that are classed as Official music ones that I have tried, so I guess an update to YouTubeDL is required.

I also know that some people have followed the instructions but can’t seem to get some vidoes to play which I can but as the software is Beta class at best I guess that is something we will have to live with for now.

At least some of us can watch YouTube in some form which is thanks to you and and a number of other people.

CPUStats?

I think it should be kept simple, so CPUCount caught my eye. But on reflection, I would go for CPUPerf (which is on Jeffreys original list) as it encapsulates what it is about. The Count part is, I think, less important.
