What's the problem exactly?

You say "first is good" and "next is bad".

Does that mean U7.1b4 is good (since that is first) and U6.6 is bad?

It would help if you said precisely what the problem is.

Anyway, I can confirm this. If you save image 20 after the loop the saved version is 1024x128 when the flag is zero, i.e. the image is stretched to the next power of two in both coordinate directions. This is correct.

Similarly, when the flag is 1 you get no stretching and the saved image is 600x100 which is also correct.

However, the paste image command uses the unstretched version in each case.

If you load the saved image back and paste that you'll get the correct behaviour as illustrated below (you can just see the stretched version at the bottom of the window):

set window on
set display mode 640,480,32
set text opaque

set text font "Arial"
set text size 70

for i=1000 to 1004
  message$=str$(i)

rem Print text message and store as image
center text 300,40,message$
GET IMAGE 20, 0,0,600,100, 0

  paste image 20, 0,200
  wait 1000
  sync
next i
save image "test.png", 20
load image "test.png", 21
paste image 21, 0, 400
wait key
end

My problem,
In screenshot, it is for bottom and the upper part to be different.
"1000 and 1001" are different.

I thought that 1000 was good,
Therefore,
The first time is good.
The next time is bad.
The version tested it in 71b4 and 66b4. It was the same.

pcRaider, when you use the texture flag 0 and change the line:

GET IMAGE 20,0,0,600,100,0
to:
GET IMAGE 20,0,0,512,128,0

is there any stretching anymore?

I believe the texture flag 0 needs image sizes like 128,256,512,1024.. and so on

You could see for yourself. There shouldn't be of course.

Quote: "I believe the texture flag 0 needs image sizes like 128,256,512,1024.. and so on"

That would be totally pointless of course - since no stretching would be needed in that case.

GET IMAGE 20,0,0,600,100,0

should produce an image 1024x128 pixels in size. It does, but only for the saved copy not for the copy used by the paste image command. They should be the same.

Read the thread again.

Why hasn't this been confirmed yet??

This bug has NOT been fixed.

I've just encountered it again today. I'll edit this post with a simple demo soon.

Edit I'll post my demo as a new bug as it may be a slightly different issue.

Er...it works fine if you delete image 20 before you regrab image 20 each loop. Or is it meant to not matter?

It doesn't matter - and it doesn't work fine.

Try this variation of pcraider's code and compare what you see on screen with what you should get as shown in the two saved files. I think this IS the same bug as the one I reported recently. So if it was fixed it's been broken again.

+ Code Snippet

set window on
set display mode 640,480,32
set text opaque

set text font "Arial"
set text size 32

do
  message$=get time$()
  rem Print text message and store as image
  text 0,40,message$

` wrong
  GET IMAGE 20, 0,0,600,100, 0 ` should be scaled to 1024x128
  paste image 20, 0,100
             text 0,100,"0: bad"
             save image "im20.png", 20

` good
  GET IMAGE 21, 0,0,600,100, 1 ` shouldn't be scaled
  paste image 21, 0,300
             text 0,300,"1: good"
             save image "im21.png", 21
  sync
loop
end
