Nth problem with hardware images

[Ikerkaz]

I know, I know. The problem is ME; I'm a complete idiot trying to understand hardware images... 
Why isn't something as simple as this working? What on earth am I doing wrong? My apologies to everyone, and thank you for your patience

Code: (Select All)

Option _Explicit

Randomize Timer



Dim As Long hardwareScreen, workScreen, Nave, Fondo, i



Screen _NewImage(1920, 1080, 32)

_FullScreen , _Smooth



workScreen = _NewImage(1920, 1080, 32)

Fondo = _LoadImage("C:\STRC\Espacio\3.jpg")

Nave = _LoadImage("C:\STRC\Naves\Constitution2\nave.png")



_PutImage (0, 0)-Step(1920, 1080), Fondo, workScreen



For i = 1 To 100

    _PutImage (Rnd * 1920, Rnd * 1080), Nave, workScreen

Next



hardwareScreen = _CopyImage(workScreen, 33)



_Dest 0

_DisplayOrder _Hardware



_PutImage (0, 0), hardwareScreen

_Display

End

You're doing absolutely nothing wrong.  It works 100% as designed.   (Which unfortunately isn't how you intended.  )

The issue? You're putting it on a hardware screen, which *WORKS*. It's displaying properly without any issues whatsoever.

So why are you seeing nothing?

Because the program then ENDs and swaps to a software screen to say "Press Any Key to Continue." <-- This erases that hardware screen.

See the only change made above to make it work? (Not counting file names so it would find test images to run on my machine?)

I just made it look for a keypress before ending, so you could see the display. Press a key and then you can see that END screen and where it's erasing your image from displaying.

Put it in a DO...LOOP like I have, with a nice limit, and then drop to SYSTEM when done and you won't have this type display error making it seem like you messed up when you didn't.

Steve The Amazing is always correct, of course.

Fondo = _LoadImage("Z:\Jan 2026.png")
Nave = _LoadImage("Z:\steve1973.gif")

But I thought that loading from a harddisk image file, you had to state the type of image as:
Fondo = _LoadImage("Z:\Jan 2026.png",32)
Nave = _LoadImage("Z:\steve1973.gif",32)

or ,33 or ,256 or some such.

Is that not necessary?

Adding that makes it convert to that format for you automagically.  Without it, it loads based on the current screen.

As per the wiki: The mode& parameter can be 32, 33, 256, or 257. Omit to use the current graphic screen settings.

@Steve, it's not working for me. The first time I tried, the screen was chaotic, but the images were briefly displayed for half a second. From the second attempt onward, it was just a black screen. I had to abort always  with Ctrl+C.

Does the board come with included janitorial service?... Because I just totally threw up on isle #7.

@Ikerkaz Have a look at some of the fun stuff you can do with hardware acceleration in screen 0. Eventually I'll merge my buttons routine into it, but for now, 5 kinds of nice drop down or popup menus.
