tga files into gui

[kiboost]

Hi,

Seems gdi+ doesn't read tga (8bits tga without alpha).

I'm writing a 64bits script that list some directories containing some tga file sequences, and I would like to show one of these tga into my gui.

Any idea how to get that ?

What would rocks would be to also be able to display 32bit rgba exr files.

No, GDI+ cannot load TGA files. If you have knowledge in C++ you can try to convert the code from here http://www.dhpoware.com/source/bitmap.html to AutoIt (no RLE supported)!

I'm just working on the bool Bitmap::loadTarga(LPCTSTR pszFilename) function but my C++ skill is near zero...

If somebody feels free to convert it please post it into this forum!

I made a DLL out of this code to load targa files to hBitmap. Hope this is useful and works as expected.

Thanks funkey, but seems you just convert the tga to bmp before showing it.

I use cmd line nconvert tools to do this into jpg and use guictrlcreatepic, works also. But native handle of tga, png, exr (16 and 32bits) would really help a lot.

Sample code just makes a bitmap from targa file. But you receive a hBitmap and you can do everything you want with it.

Hi funkey,

somehow I sensed it that you will do it. Is there any chance to do it completely in AutoIt without using the DLL? I started the conversation but I still stuck on understanding some commands in C++.

Hi UEZ, it should be no problem to do this in AutoIt. I will have a look at it when I have time. Not sure if this happens this year or not.

I'm in this project too!

I am converting some functions...

Does it do it instantely in memory ? Would be better than converting into hard file !

[funkey]

All in memory, writing file to disk is just an example.

Hello,

now I managed to convert the code to AutoIt. I hope there are not to much errors in it.

It is not that fast, but i think some improvements could be done.

Best regards

I got DLL error: 1

I also see it is 32bit, could it work in 64bit mode ?

[UEZ]

The DLL version crashes (AutoIT3.exe ended.rc:-1073741819) also on my machine (Win7 x64) but the 2nd pure AutoIt code works properly!

Btw, can you provide the DLL code?

For transparent images the black background is ugly but can be changed easily!

I will analyse your code to understand the conversation from C++ to AutoIt...

Thank you very much!

So, now you can download all I have about this. I cleaned some things in the DLL also.

Thanks a lot!
