Re: Sprites on QL

GD1 systems (ie original QL hardware) can only display sprites of the same mode as the display is in. Ie in mode 0 (4) only mode 0 sprites can be displayed, and in mode 8 only mode 8 sprites can be displayed. But, as Dilwyn suggests, the sprite format allows spites of different modes to be chained t...

Re: EXIF

I would use an existing tool. Exiftool is pretty good and it works on most operating systems (except QDOS, until someone ports Perl to it). As an example of usage, here is a command from a Windows script I wrote in 2010 that copies images from the camera to folders based on date: exiftool -r -d E:\...

Re: EXIF

Ive been there already. Doesnt give details of how to find the info in a reliable fashion, and documen...

EXIF

Im trying to help a friend sorting her photos, which are widely spread over hard disks, external devices, phones, etc. The idea is to use an SBASIC program on QPC2 to drill down every device's directory structure looking for image-type files, extracting the date and copying those images on to a sing...

Re: New mdv discovery - QL Expert (an expert system shell)

I downloaded qlexper2.mdv to have a quick peek. Knowing nothing of the various formats at the time, I fired up mdidriver_cde (V1.06, I think) and tried to mount the image. It returned Bad Name. So, naturally I went to Dilwyn's to see if there was a later version, or any other mdv image drivers. I fo...

Re: New mdv discovery - QL Expert (an expert system shell)

<>I'm not sure Per, I pretty much exclusively use Qemulator because it's closest to original hardware. Hang on, I'll pack the files into a QL zip. Thanks. I managed in the end after fannying about for an hour. It seems we have at least three different mdv image formats. I hope theres a bloody good ...

Re: New mdv discovery - QL Expert (an expert system shell)

So how does one read these images on, say, QPC2? I cant seem to find any utility that does. Martin Head's MDI driver wont mount them and his utility to convert Qlay type mdv images and Q-emulator type mdv images doesnt recognise the qlexper2_mdv image at least.
