Image Viewer with fading effect

Michael Vogel · Post by **Michael Vogel** » Wed Jul 12, 2006 2:16 pm

Hi,
I'd like to do a dia show, where all pictures are resized to full screen and faded in and out...

I searched in the forum, but all sprite commands seem to have a transparent color (128/128/128) and there are no image commands to do so... I also found a skinwindow library here, but there I get memory access errors (I don't like libraries)...

So my "solution" is a little bit crazy, I need 3 windows - one for the (black) background and two other for the fading effect - this works slow and seems to be "a little bit" complicate. So, anyone has a better solution for doing the fading?

Thanks,
Michael

Thanks to you both - I'll check these codes immediately...

Michael Vogel · Post by **Michael Vogel** » Thu Jul 13, 2006 2:41 pm

Hmm...
still having (quite a lot of) problems...

On my notebook Netmaestros code only brings up the text on a black screen - when I set remarks before the black window and even disable the #PB_Window_Invisible option for the second window, I only get a grey window with nothing in it) - I will play around in the upcoming night, but at the moment I can't get it running...

The following code (from Paul) works (when the texture size changed to 16x16), but has the following problems: I can't resize (too big) pictures to screen size, and it fades to and from black, not from opne picture to the other...

Code: Select all

fading...

If InitSprite()=0 Or InitSprite3D()=0 Or InitKeyboard()=0
	MessageRequester("Error","Could Not Initialize DirectX",#MB_ICONERROR)
	End
EndIf


Enumeration
	#Black
	#Pic1
	#Pic2
EndEnumeration

timer=AddDate(Date(),#PB_Date_Second,5)
fade=2
level=255
speed=8
pic=#Pic1

Global ScreenX=GetSystemMetrics_(#SM_CXSCREEN)
Global ScreenY=GetSystemMetrics_(#SM_CYSCREEN)


If OpenScreen(ScreenX,ScreenY,32,"Pictures")
	SetFrameRate(60)

	CreateSprite(#Black,16,16,#PB_Sprite_Texture)
	StartDrawing(SpriteOutput(#Black))
	Box(0,0,15,15,1)
	StopDrawing()
	CreateSprite3D(#Black,#Black)
	ZoomSprite3D(#Black,ScreenX,ScreenY)



	UseJPEGImageDecoder()
	UsePNGImageDecoder()


	LoadSprite(#Pic1,"1.jpg")
	LoadSprite(#Pic2,"2.jpg")



	Repeat
		ClearScreen(0)
		ExamineKeyboard()

		If Date()>timer
			timer=AddDate(Date(),#PB_Date_Second,5)
			fade=1
		EndIf

		Select fade
		Case 1  ;fade out
			level+speed
			If level>255
				level=255
				fade=2
				pic+1
				If pic>#Pic2
					pic=#Pic1
				EndIf
			EndIf

		Case 2  ;fade in
			level-speed
			If level<0
				level=0

			EndIf
		EndSelect


		DisplaySprite(pic,0,0)
		Start3D()
		DisplaySprite3D(#Black,0,0,level)
		Stop3D()
		FlipBuffers()
	Until KeyboardPushed(#PB_Key_Escape)
EndIf

I tried to change it to do "cross fading", but now it worked only on my notebook (Windows XP) at work, not at my (older) notebook at home (Windows 2000) - and I'm still not possile to resize the pictures...

Code: Select all

If InitSprite()=0 Or InitSprite3D()=0 Or InitKeyboard()=0
	MessageRequester("Error","Could Not Initialize DirectX",#MB_ICONERROR)
	End
EndIf


Enumeration
	#Black
	#Pic1
	#Pic2
EndEnumeration

timer=AddDate(Date(),#PB_Date_Second,5)
fade=2
level=255
speed=4
pic=#Pic1

Global ScreenX=GetSystemMetrics_(#SM_CXSCREEN)
Global ScreenY=GetSystemMetrics_(#SM_CYSCREEN)


If OpenScreen(ScreenX,ScreenY,32,"Pictures")
	SetFrameRate(60)

	CreateSprite(#Black,16,16,#PB_Sprite_Texture)
	StartDrawing(SpriteOutput(#Black))
	Box(0,0,15,15,1)
	StopDrawing()
	CreateSprite3D(#Black,#Black)
	ZoomSprite3D(#Black,ScreenX,ScreenY)

	UseJPEGImageDecoder()
	UsePNGImageDecoder()

	LoadSprite(#Pic1,"1.jpg",#PB_Sprite_Texture)
	LoadSprite(#Pic2,"2.jpg",#PB_Sprite_Texture)
	CreateSprite3D(#pic1,#pic1)
	CreateSprite3D(#pic2,#pic2)

	Repeat
		ClearScreen(0)
		ExamineKeyboard()

		If Date()>timer
			timer=AddDate(Date(),#PB_Date_Second,5)
			fade=1
		EndIf

		Select fade
		Case 1  ;fade out
			level+speed
			If level>255
				level=255
				fade=2
				pic+1
				If pic>#Pic2
					pic=#Pic1
				EndIf
			EndIf

		Case 2  ;fade in
			level-speed
			If level<0
				level=0
				fade=0
			EndIf
		EndSelect


		;DisplaySprite(pic,0,0)
		Start3D()
		;DisplaySprite3D(#Black,0,0,level)
		DisplaySprite3D(#pic1,0,0,level)
		DisplaySprite3D(#pic2,0,0,255-level)

		Stop3D()

	Until KeyboardPushed(#PB_Key_Escape)
EndIf

Could you post hw and os specs for your notebook please?

Michael Vogel · Post by **Michael Vogel** » Thu Jul 13, 2006 2:54 pm

My own notebook is a Fujitsu Siemens Lifebook B2175 running with W2k, ATI Rage Mobility Graphic card with 800x600, 32 Bit.

The second notebook I tried out was also a (bigger and newer) Fujitsu running with Windows XP, graphic mode was 1024x768@32 but I didn't had a look whioch graphic card it was...

The API I'm using, AnimateWindow_(), is supported for Win98 and above, including Win2000. It should definitely work, is it possible that the images aren't coming in successfully? Maybe stick a debug IsImage() line in for each of them? If that's not it I'm befuddled.

I'm going crazy - now I tried it also on my companies notebook - same black screen...

MessageRequester(Str(IsImage(100)),Str(IsImage(200))) brings up non-zero values, so the images are in the memory.

Michael Vogel · Post by **Michael Vogel** » Wed Jul 19, 2006 11:52 am

Found reason why it netmaestros code did not work (on all notebooks I have checked the program):
It's the resize command - when it is in the code, the screen stays black here... (see also thread http://www.purebasic.fr/english/viewtop ... 880#153880)

Now this is my "working" code - what means it really can cross fade (on some notebooks, not on mine

).

therefore, also a fade out/in mode is implemented, this works also on my notebook

this mode is default, it can be changed by pressing 'M'

if anyone find, what could be changed, that cross fade will also work on my notebook, this would be great...
:roll: other improvements are also welcome...

Other keys:

+/-: speed up/down fading time

f/s: faster/slower dia show (decrease/increase delay between pictures)

i: show information (and parameter values

)

space: next picture

Escape: quit

Attention:

Please change the scanpath variable to your picture directory

You should also play around with the FrameX/Y values
