loading images and mixing

I am using PureBasic for rapid development and testing for my 8bit 6502 projects.
What I am trying now for weeks is
having a screen open for gfx output, loading 2 images which I want to copy on the openened screen. these are textures where I refer to with point(x,y).
Code: Select all
OpenScreen(640,480,32,"test",0)
CreateImage(0, 320, 320)
CreateImage(1, 320, 320)
LoadImage(0,"texture1.bmp")
loadImage(1,"texture2.bmp")
...
so how can I copy the bitmaps to the opened screen? as I want to actually see them and getting them via Point command... I tried GrabImage, too etc...
I do not get the pic IDs.

StartDrawing(ScreenOutput())

DrawImage(ImageID(1), 10, 10)
StopDrawing()

You can use alpha layer as a way to combine things. You also may want to use sprites and take advantage of the sprite blending methods.

Btw.:
If you use LoadImage() you don't need to create them before.
And if you want to use a 'normal' window you can use
ImageGadget(0, 10, 10, 0, 0, ImageID())

Code: Select all
OpenScreen(1024,768,32,"test",RGB(0,0,0))
texture=LoadImage(#PB_Any,"neptunemap.jpg")
StartDrawing(ScreenOutput())
DrawImage(ImageID(texture), 0, 0)
StopDrawing()
Repeat:Until 1=0
won't work...

Code: Select all
InitSprite()

UseJPEGImageDecoder() ; <--- Remember decoder
Scr = OpenScreen(1024, 768, 32, "Draw on screen", #PB_Screen_SmartSynchronization, 60)
im1 = LoadImage(#PB_Any, "E:\1.jpg")
im2 = LoadImage(#PB_Any, "E:\2.jpg")
Repeat
ClearScreen(0)
StartDrawing(ScreenOutput())
DrawImage(ImageID(im1),0, 0)
DrawImage(ImageID(im2),500,0)
StopDrawing()
ExamineKeyboard()
FlipBuffers()

thx. seem to work...
I thought that sprite is for "sprites" only
one of my mistake was not saving the source code so the path to the pic did not work (but compiler did not throw an error...)

Sprites are better for (Windowed)Screen. And it is hardware accelerated if you need animations.
If you just need to display 2 images, a CanvasGadget or 2 ImageGadget could be enough.

and how would this work with imagegadget?

Hi,
as I told you in my former posting:
Code: Select all
UseJPEGImageDecoder() ; <--- Remember decoder
OpenWindow(0, 0, 0, 1024, 768, "Draw", #PB_Window_SystemMenu|#PB_Window_ScreenCentered)
im1 = LoadImage(#PB_Any, "E:\1.jpg")
im2 = LoadImage(#PB_Any, "E:\2.jpg")
ImageGadget(0, 0, 0, 0, 0, ImageID(im1))
ImageGadget(1, 500, 0, 0, 0, ImageID(im2))
Exit = #False
Repeat
Event = WaitWindowEvent()
Select Event
Case #PB_Event_CloseWindow
Exit = #True
EndSelect
Until Exit

thanks... got it... could not test right now following...
when I do a color=point(x,y) I get the right color doesn't matter if I am over imagegadget1 or 2?

No.
Point() is not usable with an ImageGadget().
It is only usable with the image itself.
And for Point() you need StartDrawing() StopDrawing().
Read a bit more in the helpfile.

when I am using plot/point in that example Purebasic crashes.

ok...
so how would you then solve my potential task?
load different bitmaps on 1 screen (so I can see them). and then getting pixel values with a function and draw on the same screen all at aonce?
