How to use images in Turing


You can load 3 different types of pictures in Turing. They are PCX, BMP and TIM.


1st you need to load the image into Turing's memory:

var varname :int := Pic.FileNew ("filename")


Ex.

code:

     %for a file that is in the same dir as your Turing code                                                                                                                   
      var mypic :int := Pic.FileNew ("coolpic.bmp")
     


or

code:

       %to specify the exact location of this file
       var mypic :int:= Pic.FileNew ("c:\turing\mygame\coolpic.bmp")
     


2nd you need to show the picture and set it's location on the screen

Pic.Draw (picID, x, y, mode)


Ex.

%to draw the picture in the center of the screen with no mode
Pic.Draw (mypic, maxx div 2, maxy div 2, 0)


The modes:

picCopy This draws the picture on top of what was underneath, obscuring it completely.

picXOR This draws the picture XORing it with the background.

picMerge This draws the picture like picCopy except that any occurrence of the background color in the picture is not drawn to the screen.

picUnderMerge This draws the picture, but only where the background color was displayed underneath it


If you want to get rid of the picture after you have drawn it on the screen use cls and to get it out of the memory of the computer use Pic.Free (mypic).


Example of a program that uses pics:


code:

                %program to show a logo picture
                var mypic :int := Pic.FileNew ("coolpic.bmp")
                Pic.Draw (mypic, maxx div 2, maxy div 2, 0)
               
                delay (2000)
                cls
                Pic.Free (mypic)



this was one of the 1st turealrs i made, i dont think i did a good job on it but i figered why not post. so here it is...

can you elaborate on a few things, such as how to set which background color, and what XORing means?

Post subject: 
k, all the pic options have to do with picture layering on top of eachother

picMerge will set it so that the color that matches the background is actually transparents so you can see images underneath

picCopy place the image on top of allready drawn images.

picXor inverts the color that is different than the background when a picture is touching it.

picUnderMerge sends the picture to the back so that other images that were drawn before it are still above it.

EDIT: oh and to set the background color is:

code:
colorback(color)


where the parameter is replaced with the actual color you want. (the Candian spelling of "colour" works too.)

well although Dan said that file type is supported, I've never seem it before so I sujest using something we KNOW works. .bmp and .jpeg

or maybe it just cant find the file since its on an a:\ drive? such as floppy is missing... (why would you put image file on a floppy!?).

Illigal pic ID basically means you didnt load the file.

Pic.Scale can do that.

newpicID := Pic.Scale (picID, maxx, maxy)

that would stretch a picture to fill the entire run window.

or ...

You can customize the picture before hand. Like use some editing tools, like Paint Shop Pro, and edit it, and then call up the image.

no... the 0 is the value of picCopy mode.

the problem is your picture ID, which is "mypic" variable
Author:  DanShadow [ Sun Jan 04, 2004 8:00 pm ]
Post subject: 
Yes, your program is doing this:
(mypic, maxx div 2, maxy div 2, 0)
Picture variable= mypic
x co-ordinate of picture= maxx div 2
y co-ordinate of picture= maxy div 2
value of picture= 0?????
Turing Program: 0?! Wtf does that mean!! AhhaAh! Dying!!!
The 0 has to be one of the following: (picCopy, picMerge, picXOR, etc.) I forget the rest of th em, but replace one of those with 0 to make the picture load correctly.
Author:  Mazer [ Sun Jan 04, 2004 8:33 pm ]
Post subject: 
no. 0 is perfectly fine. PicCopy is just a constant for 0.

watch:
code:

put picCopy
put picXor
put picMerge
put picUnderMerge


tada! those are four of turings draw modes. you could type those, or you could type a number from 0 to 4 instead. 4 will work as a draw mode but it doesn't seem to do anything useful.

so, to sum up, the problem was indeed with the loading of the picture. you probably had the filename typed wrong.

Put a picture named "ogre-picture.bmp" in the same directory as your turing file, try this, and tell me it doesnt work. tx

If you have a valid question, necroing a tutorial is perfectly fine. What version of Turing are you using? The original tutorial looks dated to me, written before JPGs were supported. I suggest looking through other people's code or posting your code in the help section. Then we can help better.

Post subject:  RE:[Tutorials] Pictures/Images
Every time you use Pic.FileNew, it uses a new ID (up to a max of 1000, I think). Think about what it does (do you really need 1000 unique pictures at the same time?).

The background and foreground can be conceptually different, but you have only one screen to draw on. At the point the only difference is that you draw the background first and then the foreground on top. If you clear the screen, the entire thing clears. If you draw the background after the foreground, all you'll have on the screen is the background. forks makes the computer draw stuff at random, making everything a huge mess. Stop doing that.

It sounds like part of the filename includes a character outside of ASCII's standard 0-127 values. This probably happens because \ is an escape character for special meanings; try using
code:

"H:\\Turing Game\\Map.jpg"

Although I'm not sure just how well spaces will be handled here.

lol... When you are drawing a picture using Pic.Draw (), the X and Y coordinates is the where the Bottom Left corner of the picture starts..

So if you are trying to draw the Picture at maxx, maxy (top Right of screen), you don't see the picture because it's being drawn beyond the screen.

Try drawing at 0,0..

Post subject:  RE:[Tutorials] Pictures/Images
There are a number of reasons your picture didn't load. Maybe you've mistyped the file name. Maybe the file is in the wrong folder. When it 'says some crap', that crap is usually some hint about what went wrong so you can try to fix it.
Author:  Raknarg [ Sun Oct 12, 2014 5:00 pm ]
Post subject:  RE:[Tutorials] Pictures/Images
Illegal Item ID 0 (probable cause: picture not succesful)

Your picture is stored as an int in Turing. When you're drawing or doing something to a picture, the value of that int can't be 0. If it is, it throws this error.

If your PIcture ID is zero, it's either because it's set to 0 and you didn't load a picture, or you attempted to load a picture and that picture as you specified it did not exist.
