Hi,

To run UNGIF v0.94, only the Pointer Interface: PTR_GEN is required, which should reduce your ram usage.

I suppose a non-Pointer Interface Graphics conversion programme could be written.

Update:

I could only get Qemulator to run UNGIF with 384K ram, so it looks like a 128K QL will not run UNGIF.


Regards,

Derek

Thank you for checking. I will have to see what its dataspace size is. Perhaps it's setting aside a large chunk expecting a big GIF image.

I used ungif all the time when I did my game and other graphics. I use it on QL emulator.

What were the settings you had on QL emulator?

Hi

I have Qemulator configured:

Rom: Minerva v1.98
Toolkit2
Ram: 384K

Loaded PTR_GEN

The Gif file was located on the computer native drive directory mapped to MDV2

At QL speed really slow, but Full speed, very fast.


Regards,

Derek

Oh, I did have to mount ungif as a zip file.

Or, get someone to write a version in assembler? Which doesn't need the PE etc, like a command line version?

Do I hear any volunteers? :D :D :D

Actually, I'm inclined to write a WIndows app to convert bmp to scr...no reason that shouldn't exist. There is one that does bmp to pic but it doesn't allow for any settings. But converting things into scr files from the Windows side of things would make the most sense since now days it's easy to transfer between Windows and the QL and Windows has more power and connectivity. Only problem is time...what I need is a student with a few needed credits to graduate as it sounds like a fun independent study project :-)

Edit: Actually, it could be GIF or PNG as opposed to BMP...just depends which format is easiest. From reading the stuff from Andrew's link, it states that BMP is closest to what they are doing with regard to numbered values representing pixels.

Dilwyn has loads of those at http://www.dilwyn.me.uk/graphics/index.html -- not that that should stop you having fun writing the code.

Cheers,
Norm.
