Image.LoadFromFile("sprite.tga") Won't load the im

[maninboots]

maybe you can send your project files to someone that have visual c++ and see if it will works for him..my ide can import vc projects, however no vc compiler here on linux.. Confused

Ok, here's my project folder:
http://www.hakucenter.com/spriteTest.zip

I opened / compiled / run you project without any error. The sprite is loaded and displayed correctly.

[maninboots]

Ok, now thats really weird. Did you change anything, anything at all ?
If not, I'll try and reinstall Visual Studio and SFML.

Thanks for the help ! :

[Laurent]

I just added the paths for SFML headers and libs, and linked with the debug versions of the libraries (but that shouldn't change anything).

[maninboots]

How exactly did you do that ? I'm very new to C++ (been learning VB.Net in one year and I switched to C++ like 5 days ago).
Guess it's something basic that I've forgotten..

Same problem here with code::blocks. My source is in a directory, and I got a bin/debug directory for my exe.

This path is working under EDI :
=> ./bin/debug/datas/image.gif : yes !

But it's no more working out of the EDI. So I think you just have to get a good "work path", like I'll try to do tonight with Code::Blocks  :wink:

As your program compiles and runs, I think it's not related to the project setup. It's more a problem of working directory. Did you try to put your program and the image in the same directroy, and run it directly from there ?

You can also try to compile and run in release mode (to make sure the problem is not coming from the use of release libs in debug mode)..

[maninboots]

Oh my god, I feel so stupid.. it worked in release mode ? How ?
Can I get it to work in debug mode also ?

Thanks for all the help !!

Edit: Well I can debug in release mode so I guess this is solved !!
THANKS! Very good support.. thumbs up for SFML and Laurent!

debugging symbols shouldnt be produced in release mode, maybe it can break your program but it shouldnt be able to see some really detailed info..

Ok, so how do I fix it so I can run it in Debug Mode ?

And another thing, can I load images with alpha channels ?
Photoshop doesn't support alpha channels in TGA so I tried to create an alpha with "TGA Tool", but I can't load that image in the program.

What's the use of sprites (in games) if you can't have an alpha channel ?
Is there a way to like - assign a special color to be the Alpha Channel Color (Like DirectX?),
so that I can output the image with like an Pink background and then let SFML make it transparent ?

Thanks

Just link with sfml-graphics-d.lib instead of sfml-graphics.lib (the same for other libraries -- sfml-window-d.lib and sfml-system-d.lib).

And another thing, can I load images with alpha channels ?

Yes, alpha channels are properly loaded

Photoshop doesn't support alpha channels in TGA

Really ? If so, I guess you have an old version of Photoshop.

As I said you can load the alpha channel directly, but if you want to make a particular color transparent after loading the image in your program, you can use the sfImage::CreateMaskFromColor function.

Ok Thanks !

Sorry, I meant that Photoshop doesn't support automatic alpha channel (like for GIF and PNG), you have to make your own alpha channel in the channel window.

Yes, alpha channels are properly loaded Wink

Really ? I did make an alpha channel in photoshop and then saved it as an TGA, it didn't load. Then I tried with TGA Tool and made an alpha channel , didn't load either.

As I said you can load the alpha channel directly, but if you want to make a particular color transparent after loading the image in your program, you can use the sfImage::CreateMaskFromColor function.

Ok, I'll use that function if nothing else works!

Thanks

What do you mean ? The loading caused an error ? Your sprite is showing but with no transparency ? Did you check some pixels to see if their alpha value are correct ?

[maninboots]

It seems I got it to work, all of a sudden it takes .jpg .png everything, with or without alpha channels. I have no idéa of what I did, but it works!

Finally, I can start creating stuff.

Thanks! I'll be back sometime with more errors, I can feel it

Edit: But I do get 20 Warnings .. hmm

Which ones ?
