nullschritt Posted February 10, 2014 Share Posted February 10, 2014 Hello, this is probably a simple problem, but I'm not understanding whenever I call _GDIPlus_BitmapCreateFromMemory() I get @error=3. I'm reading the image from a file, and convering the data to binary, but I still get 3 - unable to create bitmap from stream. What step am I missing?

FireFox Posted February 10, 2014 Share Posted February 10, 2014 (edited) Hi, Can you post your script ? Otherwise we can't guess what's wrong with it. Br, FireFox. Edited February 10, 2014 by FireFox Link to comment Share on other sites More sharing options...
UEZ Posted February 10, 2014 Share Posted February 10, 2014 If you are using the current beta (3.3.11.3) than _GDIPlus_BitmapCreateFromMemory has a typo in the function which causes not to run properly. But I agree with FireFox, post your script that we can see what might be wrong. Br, UEZ Please don't send me any personal message and ask for support! I will not reply!

UEZ Posted February 10, 2014 Share Posted February 10, 2014 (edited) I cannot see a _GDIPlus_Startup() in your script. Beside that, loading a bitmap from disk you can use _GDIPlus_BitmapCreateFromFile() or _GDIPlus_ImageLoadFromFile() instead.

Br, UEZ I'm only loading it from the file because I didn't feel like putting binary in the reproducer script. The function is intended to process binary data. Also in my script the udf function _PixelGetColor_CreateDC calls the _gdiplus_startup() function. Link to comment Share on other sites More sharing options...

UEZ Posted February 11, 2014 Share Posted February 11, 2014 Once AGAIN: you are mixing GDI and GDI+ stuff! Using _GDIPlus_BitmapCreateFromMemory($data, 1) means the function returns a GDI bitmap which cannot be used in GDI+. Thus you cannot use _GDIPlus_ImageGetWidth($HBITMAP) afterwards!
