Some code to load any image to a FB image (using FreeImage)

[Pottersson]

I followed the above code word-for-word (literally, I just changed the filename and tried to compile). I received the following error:

Code: Select all

F:\PortableApps\FbEdit\FreeBASIC\fbc -s gui "FbTemp.bas"
FbTemp.o:fake:(.text+0x259): undefined reference to `FreeImage_ColorQuantizeEx@20'

Build error(s)

This is the same error as was posted previously by several people, including Tafoid.

I then tried to switch out my libFreeImage.dll.a for cha0s' and got the newest FreeImage.bi. I still get the error.

I'm running FB 0.18.5 and have very little experience using external libraries. I just need a way to display PNG files using the built-in fbgfx routines. If I thought I could, I'd just write my own PNG loading routine from scratch. But as it is, it would be better if I can use a library.

I also tried using MichaelW's solution of rebuilding the import library, but I still get an error:

Code: Select all

F:\PortableApps\FbEdit\FreeBASIC>bin\win32\dlltool -k -d freeimage.dll.def -l libfreeimage.dll.a
<!bin\win32\dlltool: Syntax error in def file freeimage.dll.def:4

Any help would be greatly appreciated.

Try the link again: http://therealcha0s.net/project/libfreeimage.dll.a

I think when I was testing, I had the dll in the compilation directory, so it was using that. I updated the import lib with the latest .def in SVN, and it compiles fine here at least. Please lemme know how it works out for you.

[Pottersson]

Now I'm getting 404'd. "Cannot find server" it says.

[cha0s]

ARG XD. It should be all fixed up now.

[Pottersson]

Compiles fine now, thanks for the quick response.

Now I get this dialog box: "The procedure entry point FreeImage_ColorQuantizeex could not be located in the dynamic link library FreeImage.dll"

I just downloaded the newest dll from SourceForge, 3.10. I looked at my header, and it has the same version.

[cha0s]

I dunno. Maybe it has to do with the order Windows is searching for dll's in the path settings. Try moving/deleting the freeimage.dll that you see, and see if you get the same error. If so, there's another version of the dll laying around on your system which is causing it.

Beyond that, not too sure. I know for a fact that symbol is in the library.

Is that the actual case ("ex" vs "Ex") ?

[cha0s]

Is that the actual case ("ex" vs "Ex") ?

I thought so too when I saw it, but I checked the .def and unless some act of God happened, it's 'Ex'

Okay. I temporarily took the dll out of the folder the program was in, and tried to run the program. Windows complained that it couldn't find FreeImage.dll, so I know that there isn't an old duplicate sitting in the system folders.

I did a text search for "ColorQuantizeEx" in my FreeImage header, dll.a file, and my dll. The function turned up in all three files, but I have a question: are the entries in the dll supposed to have an underscore in front of them? Below is the only place in the dll I found "ColorQuantizeEx"

Code: Select all

_FreeImage_CloseMultiBitmap@8 _FreeImage_ColorQuantize@8 _FreeImage_ColorQuantizeEx@20 _FreeImage_Composite@16

I also tried to run the program on a different computer, and I still got the same error message. Has anyone gotten FreeImage to work?

[cha0s]

The underscores are normal.

After I have installed FreeBASIC 0.20.0b, my program isn't working anymore. I get the message "The procedure entry point "FreeImage_Allocate" in FreeImage.dll isnt found".

FreeImage.dll is located in my program's directory and in the system directory.

Could somebody PLEASE give me his .def and .a file?!

[Cherry]

I finally managed it by myself - here you have working .def and .a-files for FreeImage 3.11.0:

Anyone here have conversion from fbgfx back to freeimage?

[LukeL]

Check this out for fbgfx to freeimage... http://www.freebasic.net/forum/viewtopic.php?p=107994
There should be enough code there to get a FreeImage buffer with modification.
