Downscaler/Upscale image

I use WinApi routines to load icons. If I request a resolution of, say 80x80, and there is an icon with size 256x256 available, then Windows does a pretty poor job of downscaling the images. I didn't bother trying to find a way to make Windows improve the quality (in case there is one) but had some ...

Re: How can I close this file (and only this one)?

@Tourist Trap: Is there a reason you can't use a global variable to store the file number you used? If it's the case that your program is going to be opening files in an unpredictable way, there are a number of ways of dealing with this. Perhaps you could clarify? In fact I'm just pointing out the ...

Re: How can I close this file (and only this one)?

Perhaps I misunderstood what was written above but the following seems dangerous: open ... as #freeFile() dim as long ff = freeFile()-1 close #ff As far as I'm aware, internally, there is an array of file handles. freeFile simply returns the smallest index into the array with an empty cell. So you c...

Re: HICON to FB.Image

At last have an implementation which is OK ;-) It still doesn't account for all possibilities but I'll leave it for now: Sometimes icons don't specify the used colour depth. I could try to use external libraries to determine the colour depth (I don't want to do that) or look at the image format spec...

Re: Why won't this video show???

EDIT: Previous answer was incomplete.

System: Win7, 64-bit

FBC 64-bit (1.05.0): No problem here as well. Also the sound plays in sync.
FBC 32-bit (1.05.0): No video here. Sounds plays well. One video flickers -- looks like a race condition --> dkl's answer.

Re: Boolean? Or integer?

To all reading this: Do you prefer to write loop until cbool(unique = true) andalso (in <> "") since it implies that unique is a boolean variable? Or rather the following which is shorter (and requires no cbool() ): loop until unique andAlso (in <> "") I would probably rename uni...

Re: FB 64-bit gdiplus include problem

Yes, including windows.bi beforehand works. So basically the problems boils down to that

Code: Select all

namespace XX
    declare sub test()
    #undef test
end namespace
isn't allowed.

HICON to FB.Image

Hi, I'm trying to convert an icon, retrieved by extractIconEx() , to an FB.Image. However I cannot find an easy way of determining if the icon is 32-bit or lower. If the icon is lower than 32-bit, then the alpha channel is zero. If displayed with put (x,y),img,alpha , you won't see anything. Thus I ...

Re: Is this supposed to be allowed?

Interesting. Although it seems like a dangerous coding style. A compiler flag disallowing such behaviour would be nice.
Thanks for clearing this up fxm.

Re: [solved] Can you post your FPS result please ?

Really cool what can be done with just a few hundred lines of code! Joshy's code: I get a solid 60 fps (minimum 58 fps) on a (mobile) Nvidia GTX860M. On the Intel processor integrated HD Graphics 4600 I get a minimum of 10 fps, a maximum of 25 fps and an estimated median of 12 fps (other stuff, e.g....
