Cross fade effect between jpeg images in autoit is it possible?

[fusion400]

Is it possible to make a crossfade effect between different images in autoit and show it in fullscreen mode?

My idea is to be able to display a playlist of jpg images for about 5 seconds each that has a smooth cross fade effect.

Yes this seems to be on the right track the only thing missing is that it doesn't actually cross fade between images it rather fades them in and out one by one. Rather then crossfadeing between images and it seems to not initiate any fullscreen mode.

This is the more exact definition for a cross-fade:

A lap dissolve (sometimes called a cross-fade, mix or simply a dissolve) is a technical term in film editing, most often used in the United States, applying to the process whereby the fading last shot of a preceding scene is superimposed over the emerging first shot (fade in) of the next scene, so that, for a few moments, both shots are seen simultaneously. Generally, but not always, the use of a dissolve is held to indicate that a period of time has passed between the two scenes.

I made an image-viewer using SDL that has some sort of crossfading. ShiftER. Use Effect 2.

Feel free to borrow ideas or code if you want

You can reduce the inner loop stepping value, pictures will blend-over more softened but slower.

Change the necessary parts. Search the Examples forum for GDIP.au3.

[fusion400]

Ok i have tried this and it works but its horribly slow and the stepping is not smooth for one bit and extremely slow.

Maybe there is something wrong. I also tried to use images that perfectly match my desktop resolution but it did not

make any difference.

I am running windows 7 maybe there is something wrong that makes this not work well on win7.

well Auth said...

perhaps there is a clue somewhere in there about a way you could try to speed it up... Or you could of course take his other advice, or better yet post an attempt at doing it yourself instead of complaining at someone else's attempt.

Download the attachment for includes. Also, you need to download AutoItObject UDF, thanks to the developers by the way.

Edit: Fixed _D3D_Init function and the flickering. (hopefully)

Authenticity cool!

I just tested that script (after downloading d3dx9_36.dll). Works great.

Wrapper object in current version of AutoItObject is rewritten not to use callback, btw. I tested your script in this new situation. Works too, even better.

What I can see is that you call Release() for od3d9 before returning from _D3D_Init(). You probably shouldn't. If that call actually worked script should crash on later reference to that object. Now Release() fails because you are calling it wrong (no ret type specified).

Again, very cool! Thanks for sharing.

Thanks. You're correct about my mistake. Can you elaborate on the callback thing? I'm using AutoItObject v1.1.0.

P.S. Is there like a garbage collector in AutoIt? or something similar? I can't believe that such a simple script can use approximately 200MB of RAM o_O

Callback function was used in 1.1.0 to execute object method. Things were prepared outside the script code and then the control was returned to AutoIt to actually call wanted method. After that control was retaken again and results of the call processed. This was due to the fact that it was easier not to implement DllCall() inside our dll.

This method has different disadvantages. For example besides being damn slow you can't use datatypes other than AutoIt supports.

After implementing Invoke that doesn't use AutoIt's script code (no callback) 'everything' is possible; we introduced variant data type for example, since it's often needed with different objects.

Will be public if testing turns ok. Looks very promising for now. All is available in development.

I don't have that high RAM usage for your script. It's more like 11MB. Windows7 x64.

Problem is line 25: $pTextureOut = _D3DX_CreateTextureFromFile($pDevice, $sFolderPath & "\" & $aFiles[1])

Used: latest version of AutoItObject and AutoIt on Vista x32.

That sounds very very promissing Authenticity!

Check that $pDevice is not a null pointer. I can't think of any other reason why the script failed... If $pDevice is null you'll need to see check the _D3D_Init function.

[UEZ]

d3dx9_36.dll was missing!

Sometimes it flickers when changing the image but great implementation!

Can we expect a D3D9 UDF soon?
