My main purpose is to raise this as a serious matter, and on the whole the discussion has had the right balance of serious comment, humour and passion, I don't know, I have a VERY hard time taking this subject seriously at all.

Re: [Ql-Users] Drawing on the pointer coordinate system

I would like to hear how the cracks would tackle a problem I have where I have some alternative solutions for. (My programs are SuperBasic, liberated or Turbo-ed) How do you draw graphics in the pointer coordinate system (a typical application would be things like rubber-banding or a shape drawing program)? The options I currently see are as follows: 1. Use the Graphics coordinate system - Here I find it next to impossible to find a perfect match between pixel coordinates and graphic coordinates using SCALE (Or am I just doing something wrong?). I'm doing something like SCALE #channel,windowHeight%, 0, 0 and POINT x,y-windowHeight%. This (at least sometimes) hits the spot, but not with acceptable accurracy - the point plotted is always a bit off the pointer position. Advantage is, you can use INK, PAPER, and he like and have all the graphics drawing for circles and arcs available 2. Use BLOCK - this hits the spot perfectly, because it uses pixel coordinates. You can also take advantage of INK and PAPER and the like, but need to write your own routines for drawing shapes, rectangles, arcs, lines. This could end up in a huge pile of work, the program could also tend to be slow with implementation of these primitives in SuperBASIC. 3. Use the Draw line of blobs/sprite functionality from PE. Uses the pixel coordinate system, so we'd be safe with pixel accuracy - Cannot use INK, PAPER and the like, because you define the colour in the sprite. You'd need to have an assortment of pixel-sized sprites in order to be able to draw in different colours. Shapes like rectangles and circles are not available as well and need to be emulated. 4. Use own, machine code-based SuperBasic extensions to plot and draw in the pixel coordinate system. Not sure whether I would want to tackle this one, especially if I want my program to be able to run both on standard QLs and GD2-Based systems (Or is there something already available - I'm not aware of such an extension - There was an article in an old QL world, part of the DIY toolkit, but this would hardly work in a GD2-based environment. What's common practice? Like to hear some recommendations. There is an simple drawing program using the Pointer Environment in example 3 of TurboPTR. This example allows you to use the mouse to draw shapes on the screen (in various different colours). The general method is to find the pixel position of the mouse on the screen and to draw a line between that and the previous position if it is different. This is repeated until the mouse key is lifted. The line is drawn using blocks of size 2x1. It is not practical (or even possible) to use both pixel position and graphics coordinates for the same point on the screen. The code for the program is in the file EX3_BAS in TPTRX03_ZIP which is on the SQLUG site at: http://jms1.supanet.com/SQLUG/gwilt/gwilt.htm The program compiled by Turbo is in EX3_TASK. An explanation of how to use the program is in PROGRAMS_TEXT. All these files are in the same zipped file, TPTRX03_ZIP. George ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

I should have realised that a genius like Rich Mellor would make the impossible possible. Nevertheless my program does the simple line drawing without the need for Rich's BASIC rewrites.

Re: [Ql-Users] Punters
Hi Roy, I intended to come and help Dilwyn with QL on a Stick, and Steve Reyal wanted to go too. My wife works weekends, only for about 4 hours in the mornings, but its the busiest time of the week and seldom gets weekends off. and with two kids I couldn't leave them alone - its almost impossible to find babysitters out here. I miss the shows a lot. The joys of Fatherhood. Still I wouldn't change it for the world. Yes, looks like I'll have to get the finger out for an Irish Show - Inebriation Eireann IV I think... Anyone any preferences as to when ??? Cheers, Darren. Roy wood wrote: Hi, I thought that you were going to comer to Birmingham. I was looking forward to seeing you.

Re: [Ql-Users] QL on a stick
I used to work for CMS Peripherals here in Ireland and I recall Roy having dealings with them in the UK too. They make the disgo and Busbi USB Sticks on sale in Dixons and PC World etc. 128Mb Sticks are obsolete now in PC terms so if they had any left in stock I'm sure I could get a few at bargain prices. I still have a few good mates there and could get them at near to cost. Is there any interest? I think the period of intending to supply them on USB sticks is gone. This is why I put it on a CD - people can copy it to a USB stick of their choice rather than be held to a 128MB or 1GB or whatever size we choose.
