Images all white on iOS, work fine on Mac about soil2 HOT 5 CLOSED

Can you print SOIL_last_result after the image load and also print the width, height and channels returned?
Are you sure that the path provided is correct?
Can you try to load the texture using SOIL_load_OGL_texture?
May be you forgot to set the GL_UNPACK_ALIGNMENT to 1?

I need a little more info,
Thanks!

Yeah it does works using SOIL_load_OGL_texture, but I was using SOIL_load_image so I could get the width and height right away. SOIL_load_OGL_texture returns correct width and height but the image gets all white.
Alignment pack is set to 1 so maybe the problem is just the SOIL_load_OGL_texture function itself.

it returns "Image loaded"

I think you forgot to set the min and mag filter,
i thought that:

#!c

    GLint min_filter = filter_to_glint(GFX->get_image_min_filter());
    GLint mag_filter = filter_to_glint(GFX->get_image_mag_filter());

was setting the filters, but it seems that not.
So, after glTexImage2D you must do something like:

#!c

glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR );
// Also set the clamp mode
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP );
glTexParameteri( GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP );

That should solve the problem.

If SOIL_load_OGL_texture then SOIL_load_image it's working ( since it use that function to load the image, also it's returning the size and channels, that means that it was loaded ).

But, i recommend you to load the texture with SOIL_load_OGL_texture, and to get the image dimensions you could use: stbi_info.

It should be something like:

#!c

#include <SOIL2/stb_image.h>
...
int w, h, c;

if ( stbi_info( filename.c_str(), &w, &h, &c ) )

{
    unsigned int textureid = SOIL_load_OGL_texture( filename.c_str(), SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, 0 );
}

Now that i see this, i think it would be handy to have a load texture method that also returns you the image info, or at least expose stbi_info as SOIL_image_info.

But there's also a simpler solution for this:

#!c

int width, height, channels;

unsigned char* data =
    SOIL_load_image( filename.c_str(), &width, &height, &channels, SOIL_LOAD_AUTO );

if ( data )
{
    unsigned int textureid = SOIL_create_OGL_texture( data, &width, &height, channels, SOIL_CREATE_NEW_ID, 0 );
}

SOIL_free_image_data( data );

Hope this helps,

That last solution you gave me works perfectly. My old code, even adding the glTexParameteri still give me the same problem but it's probably something else on my end.
Thank you for all the help, sorry for cluttering this with something that wasn't even a bug after all.
