I was struggling yesterday with similar problem...

try InitSprite() before opening screen...

InitSprite()

CreateImage(0, 800, 480)
OpenWindow(0,0,0,800,480,"Fractal Lines",#PB_Window_SystemMenu)
OpenWindowedScreen(WindowID(0),0,0,800,480)

fcking cool. I overread the startdrawing(screenoutput()) instead of imageoutput... now works!

InitKeyboard()
InitSprite()

CreateImage(0, 800, 480)
OpenWindow(0,0,0,800,480,"Fractal Lines",#PB_Window_SystemMenu)
OpenWindowedScreen(WindowID(0),0,0,800,480)
;StartDrawing(ScreenOutput())
frame=0
z0.w =100

camx.w=0
camy.w=-40
camz.w=0

Repeat
ClearScreen(RGB(0,255,0))

For i=0 To max ...

well... actually 5.11 tells me to use initsprite() before?

Clearing screen or what is best practice having

I am opening a window with:

If CreateImage(0, 640, 480) And OpenWindow(0,0,0,640,480,"Fractal Lines",#PB_Window_SystemMenu)
...

and do simple 2d drawing (linexy) with
StartDrawing(ImageOutput(0))
StopDrawing()

but how can I clear the window and ...

thx Bernd... got it...

good thing is that when inserting plot or line that the coordinates are based on the active canvas.

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?

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

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?

and how would this work with imagegadget?

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...)

won't work...

thx. but I only get a white screen on OSX...

can not be so difficult... Using 5.22.

so actually I want to place a texture where the "bars" are...

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).


OpenScreen(640,480,32,"test ...
