Tonight I decided to finally spruce up and finish my old Paint Pixels saga. lol This is the drawing program I made over a month ago that uses the mouse to draw and an awesome color picker that B+ gave me to use. You can also save, load, and print on the printer. The reason I never finished it was because I was bummed that I had used the wrong code making JPG pictures. Instead I was just actually saving .bmp code as a .jpg name. So I changed it to only use .bmp pictures like the code is supposed to do. I also fixed one major problem I had with renaming the temp.bmp, which for some reason wouldn't change to the name you wanted if that name already existed. So I used SHELL to delete the old one and then rename temp.bmp to the new name you want it to be. Thanks also to B+ for the code I used on my calendar making program that rotates a picture 180 degrees to print on the printer as a landscape rather than what it was before and squishing your picture to a letter size on the paper. Thanks B+, I also kept your name as well as mine on the credits on the welcome screen. Plus I edited a tiny bit on some text within the program to make it look a little better. Please tell me what you think of this little program. I know Windows Paint is better, but I like how you can paint with this program on a FULL screen with nothing else on your entire screen as you paint. I am really happy it's finally finished, unless of course someone finds a problem with it that I need to fix. Thank you.
Here it is:

Code: QB64: [Select]

'This program was finished on October 5, 2019.
'Technical Notes:
'This program uses around 55 MB RAM and 1% of the CPU on my semi-new computer.
'Use at your own risk. I hold no responsibility for any problems whatsoever.
'
'Thank you to B+ from the QB64.org forum for the color picker and the picture rotation code!

Nothing happens when I press "space" or "enter"...
What is wrong ?

...
What interesting is, in this program, is the fact to choice easily a color and get his code.
Why not put this color code in the "_clipboard", for instance to use it when creating QB64 program using colors ? ...

What is wrong ?

It took me a couple of tries = reads of Ken's instruction But if you press space bar at opening screen you will skip instructions, just as Ken instructed. You do have to read carefully, it is not super intuitive, but on my test all seems to work as Ken describes.

I was surprised that the Orbit draws half the radius or diameter I was expecting and is it circle or ellipse? I do like Ray drawing, maybe it could use LINE -STEP for repeating R's so don't have click start points all the time but draw next Ray from last point R was pressed?? Maybe go into a R mode with one R press and then draw line from point to point clicked of course then you need R press again to toggle R mode off, something like that? BTW THAT would also fill in all those dots when just sweeping the mouse around the screen.

(More): THEN with completely enclosed areas you could use PAINT to fill them in ie PAINT to border of last Color you draw with?

Thanks B+. Yeah awhile back I tried to fill things in but for some reason it doesn't work well, especially when the program often leaves gaps when you don't draw slow enough. I'll look into the rays and ovals better. They were just something I threw on there in the beginning. Going from point to point on the rays seems like a good idea, I will try to make it off and on, so people can turn it off and then go to a separate location and turn it back on if they want to put a ray somewhere else. Awesome idea, thanks!
Euk., I'm not sure why you are getting that problem, everything seems to work on my end, but I'll look into it later today.
Thanks you 2!

Edit: I think the hardest thing about using the PAINT command is that it requires the same color as the border around it. So if someone chooses a different color than the border, it won't work.

OK, I brightened the instructions and made it easier to read. I also changed the way the orbits (circles) are made that is a bit better. I used my SIN and COS code instead. But as I say in the instructions, the more diagonal your 2 presses of the key O are apart, the more of a circle it will be. If they are horizontal or vertical, they will be almost a straight line instead. I tried to change the Rays (lines) as off and on, but figured out that it would be too difficult to remember the right keys to press to turn off and on AND make the rays. You can't just use the R key for both, so I gave up on that. Thankfully it does leave a mark on where the line starts so you know where that is when you press the second R to make the line. I also changed the (H)ome key to (I)nstructions to make it easier to remember if you need to read the instructions again. That's all I've done so far. Here is the newest version:

Hi Ken,

Here is code change to make R toggle on and off and to draw straight lines from click to click while in R mode.

Code: QB64: [Select]

    'Here is the Ray Lines code.
    IF a$ = "r" OR a$ = "R" THEN
        rMode = 1 - rMode
        IF rMode THEN lastx = mouseX: lastY = mouseY 'set first lastx, lasty
        'ck = ck + 1
        'IF ck > 1 THEN GOTO ray:
        'xxx = mouseX: yyy = mouseY
        'LINE (mouseX, mouseY)-(mouseX + 1, mouseY + 1), clr~&, BF
        'GOTO firstray:
        'ray:
        'LINE (mouseX, mouseY)-(xxx, yyy), clr~&
        'xxx = 0: yyy = 0
        'ck = 0
        'firstray:
    END IF
    IF rMode AND mouseLeftButton THEN LINE (lastx, lastY)-(mouseX, mouseY), clr~&: lastx = mouseX: lastY = mouseY

That is so awesome. Thanks again B+!!! I added it to my program. I also drew 2 examples that people can do with this program. This program has turned from a simple experimental program to something pretty high-tech, in my opinion.

Here is the update:

Code: QB64: [Select]

'This program was finished on October 6, 2019.
'Technical Notes:
'This program uses around 55 MB RAM and 1% of the CPU on my semi-new computer.
'Use at your own risk. I hold no responsibility for any problems whatsoever.
'
'Thank you to B+ from the QB64.org forum for the color picker, the picture rotation code and
'the ray line making code!

Hi Ken,

Have you realized yet, what we did for Rays we can also do also for Orbit (modeO or Omode) and Boxes (Bmode) when in those modes the first click sets the x1, y1 center for Orbit and the 2nd sets the corner for Box or Orbit Ellipse/Circle to draw.

PLUS!!!! you can _putimage of a snap shot / copy of the main screen at the beginning of a loop as back ground and then as mouse moves around in say the Rmode, you can show a ray from X1, y1 to MouseX, MouseY until user clicks the mouse again which will "set" the ray where mouse is permanently by taking a snapshot of the picture. You build the picture from snapshots at every second click in O or B mode and every click in R mode and every mouse move in No Mode.

Wow B+, I knew there was a way to do this, but I had no idea where to start. I will look into this real soon. That would make circles, boxes, and rays a LOT easier to work with. Thanks, I have to do some things but if I have time I'll get to it later today.

SierraKen · « **Reply #11 on:** October 07, 2019, 05:41:15 pm »

I am SOOO close! But I came to (hopefully) a small snag. I'm using _COPYIMAGE and _PUTIMAGE and whenever the finished image is put on the screen, that you place a ray with using the mouse, the whole screen moves down a couple of pixels. I have no idea why. I've looked the numbers over many times and don't understand why this is happening. Is it a fluke with _FULLSCREEN ? Anyway, please check it out and see if you can help me. I haven't done the orbits or boxes yet except I have put all of them in their own modes now, as you suggested, and they work great with those! I just want to use the mouse with _PUTIMAGE like you said. Thank you. If we can figure this out, then we can figure out the orbits and boxes very easily.
On a side note, I found a problem using the right mouse button to erase, so I fixed that. I think I never finished that part to begin with, so that's good now.

I removed a COPYIMAGE and a PUTIMAGE since they were not needed, but it still does the same thing, pushing the bottom part of the screen down a few pixels every time I press R.

Code: QB64: [Select]

'This program was finished on October 6, 2019.
'Technical Notes:
'This program uses around 55 MB RAM and 1% of the CPU on my semi-new computer.
'Use at your own risk. I hold no responsibility for any problems whatsoever.

Hi Ken,

I don't think I want to wade through all your goto's :P

But on line 196 I see a CopyImage statement, that I thought you removed?

This is in the wrong place anyway. A snapshot of the screen should be after drawing a line with the end point clicked in.

Before then you are drawing lines from first click to mouse position but NOT saving the screen image.

To save a screen image, I prefer this method:
1. set up a new handle say picture&
picture& = _newimage(numbers same as screen setup) 'this is your storage container

when the 2nd point is clicked in for Ray:

_putimage , 0, picture& 'source to destination = screen to container

then at beginning of next drawing loop erase old screen by placing the image in picture& contain to screen:
_putimage , picture& , 0 ' container to screen 'always right after the start of loop

Code: QB64: [Select]

'Here is the Ray Lines code.
    IF a$ = "r" OR a$ = "R" THEN
        rMode = 1 - rMode
        IF rMode THEN
            lastx = mouseX: lastY = mouseY 'set first lastx, lasty
            ''''''''''''''''''''''''''''''j& = _COPYIMAGE(0)
        END IF
    END IF
 
    IF rMode THEN 
        LINE (lastx, lastY)-(mouseX, mouseY), clr~&
        '_display 'if you are using it
        if mouseLeftButton = -1 then _putimage , 0, picture&
    end if

Interesting. I think I just tried your code but when I move the mouse without pressing the mouse button, it just makes a bunch of lines without animating the line first before you place it. This is what I have so far for this section. I'm not sure if I have the _NEWIMAGE code in the right place either.

Edit: See, I was using the _PUTIMAGE to put the entire screen back to where it was when you moved the line around without placing it yet.

Code: QB64: [Select]

    'Here is the Ray Lines code.
    IF a$ = "r" OR a$ = "R" THEN
        rMode = 1 - rMode
        IF rMode THEN
            lastx = mouseX: lastY = mouseY 'set first lastx, lasty
            picture& = _NEWIMAGE(640, 480, 32)
        END IF
    END IF
    IF rMode THEN
        LINE (lastx, lastY)-(mouseX, mouseY), clr~&
        '_display 'if you are using it
        IF mouseLeftButton = -1 THEN _PUTIMAGE , 0, picture&
    END IF
