GDIPlus_ImageResize error 4... ok, so how do I fix it?

[Sori]

My program is supposed to resize an image. It fails and displays a black image on the screen and seems to never really recover from this. After some exploration, I found that I was receiving error #4 with the resize command.

4: unable to copy image to scaled bitmap

Well that's great and all... but how do I fix it?

Show us the code to analyse what's wrong with it.

Error 4 means that the image handle you have provided cannot copied to the local bitmap within the function.

Is your image parameter really a handle?

It takes a bit of time to get the glitch to occur. I'll see if it's that particular image causing trouble.

Some other notes to take into account...

I notice the glitch after my monitor turns off. I intend to do further testing with that. (keeping the monitor on, and seeing it if glitches)

First, this line makes no sense

_WinAPI_DeleteObject($smhHBmp) ;release GDI bitmap resource because not needed anymore

$smhHBmp is a string not a GDI handle!

 

Second debug the $smGdiPic line

$smGdiPic = _GDIPlus_BitmapCreateFromFile($smhHBmp) ;convert GDI bitmap to GDI+ bitmap
    ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $smGdiPic = ' & $smGdiPic & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console

What is the return ($smGdiPic) / @error value? Edited March 23, 2015 by UEZ

I think that's supposed to be:

_GDIPlus_BitmapDispose()

I never even noticed that I messed up that line >.>

Thank you

I can't find the example script I had found that in... Looking over it, I probably changed something in their code, rendering the line obsolete.

Second debug the $smGdiPic line

$smGdiPic = _GDIPlus_BitmapCreateFromFile($smhHBmp) ;convert GDI bitmap to GDI+ bitmap
    ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $smGdiPic = ' & $smGdiPic & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console

What is the return ($smGdiPic) / @error value?

 

When running without glitches I receive

@@ Debug(388) : $smGdiPic = ;various 0x0#### codes

>Error code: 0

I'll lower my screen shutoff time and let you know what happens.

After the screen cutoff, I waited a few moments then moved my mouse. Everything is still running normally.

It's going to take a bit for the glitch to manifest.

I suggest you add an error check whether $smGdiPic is not 0 and @error = 0 -> everything should be work.

I'm not sure what you're suggesting.

I do have a question about GDI's internals...

The image is in a state that it is changing every 2 minutes. There is no disposal of the old image data, it simply writes black over the screen, then replaces the previous variable data with new ones.

Does that create memory leaks or is the data overwritten when the variable is changed?

Sorry, but without the script I cannot see what's wrong!

Not tested on my system!

[Sori]

It's running now, I'll let you know in a few hours.

All you added was to dispose of the pic before resizing?

[UEZ]

Yes, I assume a memory leak has occured caused by the GDI+ functions without disposing the resources.

[Sori]

Several hours later... Hasn't crashed yet.

Next test is to compile it into an exe and run it again. But, I think it was a memory leak.
