QL USER type-in programs

Pentahlete - by A Didcock

I fixed the bug in javelin event and added a title screen.
The published program had a LBYTES mdv1_title line, but of course the screen was missing from the magazine. So I just draw one.

Hi,

Nice prog and initial screen, I noticed `title_scr' is some 32798 bytes in length.
Is this on purpose?

Code: Select all

Oh, sorry - I forgot to strip the 30 bytes file header that QEmulator uses.
I have fixed it and reloaded the zip file in my previous post.

Making QL Graphics - I just use Photoshop. For this screen I used the "quick and dirty" way: found some clipart on the internet, collated it in Photoshop, changed the image mode to Index Color using the QL Pallete and saved the file as .raw
Then I loaded the raw file in a short QL Program to convert it to pixels.
If anybody is interested I will post the palette and the ql program .
For more complex images you also need to take into account the aspect ratio of the QL screen and scale the photoshop image accordingly, otherwise the image will be much taller than the one you see on PC. Especially in mode 4.

Perfect, can I do similar trick with GIMP, can you please help with defining QL palette?

In case it helps with the type-ins, here's a, err, list of listings from QL World, as a PDF file. On my hard disk from 2014 as a spreadsheet, not sure who compiled it! Not just the type-in programs, includes listings from other articles.
