--- Comment #8 from Yorik van Havre yorik.vanhavre@gmail.com 2011-04-02 10:00:56 CDT --- Wine 1.3.15 + sketchup 8.0.4811...
Just found another piece of information, the .jpg, .png or .bmp images produced are not invalid. They actually contain correct image data, they open fine in any image editing application. They are just filled with black or transparent pixels.
When exporting an image, the following message appears on the terminal:
err:wininet:HTTP_HttpOpenRequestW Unable to escape string!(L"/3dwarehouse/activate-importexport/?cid=3cddfd6c-69f3-45b0-a4eb-4e792893bff4&ctyp=sm&cv=p8.0.4811&hl=en-GB&pdir=e&pext=png&pname=Portable Network Graphics (*.png)&ptyp=png&suhl=en-US") (-2147467261)
(just replace the png part with other image formats, but it's the same message everytime). Not sure what it means and if relevant... Would sketchup check for something online each time it exports something? But that would prevent it from working offline... Couldn't find any information about that on the net anyway.
I'll have a look if it solves if I use native wininet...
