PureBasic Forums - English

Hey Thorium, thanks for the super clear example!

I think there's a relationship problem with Plot() and Point() when used with sprites. It becomes more apparent when dealing with large sprites.

The code below will crash.

InitSprite()
OpenWindow(0,0,0,640,480,"void",#PB_Window_SystemMenu | #PB_Window_ScreenCentered)
OpenWindowedScreen(WindowID(0 ...

What the hell ...

The reason Plot() is so slow is actually the use of Point() :!:

Without this command Plot() is faster than Box():


I'm confused ... :?

Yeah strange... Point() must not like sprites. It seems fine with images. Plot(x,y,Point(x,y)) is faster than Box(x,y,1,1,Point(x,y)) when ...

Update:

I've realized I was using an older version of Purebasic when I first tried Plot(). Plot is fine with the latest version.

Problem solved

Please note than since 4.40, Plot() isn't that slow anymore, so it could worth a try.
It's still very slow and rather useless. Use Box() instead (can be used outside "drawing area" as well).

Seems drawing to a window produces unpredictable timing results. Try drawing to an image.

When ...

I actually did it with Plot() before asking on the forum, the process was too slow. Plot would be okay if I was working with small images, but I'm dealing with images as large as 4096*4096.

I never really ...

DrawingMode(#PB_2DDrawing_AlphaChannel)
DrawImage(ImageID(I), 0, 0)



I had already tried this approach but it seems that only the alpha channel from the source image is copied to the alpha channel of the destination image. So in my situation the alpha channel in the source images doesn't ...

Hi folks,

I see that it's possible to draw shapes to an alpha channel, but is it possible to draw images to an alpha channel?

Basically I need to be able to transfer either the red,green or blue channel of an image to the the alpha channel of another image.

Or to be even more clear - I'm looking ...

I've also tried getting some text onto a full 3D screen using various methods listed in this thread and I've not had any luck.

and the link to the Gadget3D example in the docs is broken.

Ya know, I was kinda hoping somebody would say that. Thanks!

Now I gotta go figure out how to do it.

Yeah sorry, I was a little vague.

Thanks!

Do additive shadows work in a scene that contains both terrain and water?. I've tried it and I can't seem to get those shadows working.

Where are the vampires gonna sleep?

Okay, well with you guys being so sure that it worked I finally carried out some *proper* tests and it does indeed appear to be "working".

I think the problem was that I was expecting a little more smoothing than it was giving. So it was easy to overlook the effect with the type of images I was ...

Hi Folks!,

Does anybody know of a workaround for ResizeImage() not smoothing the images as advertized.

I tried with and without the PB_Image_Smooth parameter and still no smoothing. Just raw, raw and raw.

Any suggestions would be greatly appreciated!

Thanks!
