My friend create game. This similar ZX Spectrum graphics.
Have screen 256x192. And use AutoStretch to resize screen X2 or X3.
But seems very smooth, not pixel perfect.

Is it possible to do some kind of trick for Windows so that the picture is not blurred?

I found quite interesting and powerful library. I think it could become a viable alternative to conventional GUI in PB.
In mode Full Screen and WindowedScreen.

And it is not just a library. This entire GUI creation paradigm.

Uses StickyWindow(#Win_Splash, #True) to keep splash windows on top.

and you joker
I animation is created in real time.

Thx!
But... loading have animation.
Like ZX Spectrum screen loading.

Hi,


EnableExplicit


Enumeration #PB_Event_FirstCustomValue
#Own_Event_InitFinished

Ok, but now I need to do ThreadSafe application. A ThreadSafe programs run slower than usual. It turns due SplahScreen entire program will then run slowly ...

I try to formulate the task:

I have a program, opens a window will ship a lot of files, creates a lot of gedgets etc.
It lasts about 5 seconds.

While this is happening, I wanted to open a small window and display it loading animation.

By the way. How can I do waitevent if this window is used to display during loading and initializing the main program.

I have a block with WaitEvent.

But how would I have wanted to isolate the creation and closing of windows in a separate procedure?

I do not want to have a bunch of messy code in the main body.
How to be?

The timer never triggered. I can not understand why!



#loading_window = 0

Procedure Loading()

CallDebugger
Static img, Dim border.l(1)

If img = 0

img = LoadImage(#PB_Any, "loading.png")
border(0) = RGB(0,0,160)
border(1) = RGB(160,160,0)

EndIf

Yes, printer has a resolution of 720dpi, and as I print Pixelart, I decided to multiple zoom 6 times.
And I was able to fit in 8192x8192. )

(Atari, Amiga, C64, ZX Spectrum gfx)

I want to order printing on wide-format printers.
I have a lot of pictures of which I want to create one. The size of the final image obtained 36,000 pixels wide (1.3 meters).
Purebasic can create 8192px only.

How can I solve this?

A few more thoughts ...
- If the Atom supports AVX, that might be a way to increase the speed some more of the module I posted.
- It's also possible to add two additional procedures that output directly to 25 or 50% size if you need smaller images.
- Did you use SSE2 for the mixing also ? If not ...

I'm in real time converts 7 images. My version hesitate about 50-55 fps. Your version gives 62-64fps.
It's at least a few more frames per second. :wink:
Are these fps for a complete Spectrum emulator or just the screen conversion ?
If the procedure itself I created can only execute about 62 times ...

I tried a SSE2 version since I like old 8 bit computers.
Please let me know how it performs compared to the original code.

#FlipY and #SwapRB can be used to configure the output.
The colors were taken from the javascript source of a spectrum emulator.
You can change these as you like.


Thank you ...

perhaps it makes sense to use sse2 instructions?
If you do that it's best to decode one 8x8 pixel block after the other so you don't have to load the attributes so often.
But using SSE2 only makes sense if you always need to output to a 32 bit buffer.

It helps to know what your goal exactly is ...
