Re: vm_allocate error

Hello Philippe,

Same problem happens with 5.08.

I have tried some PNG files.
 From my simple test, gray scale PNG is not displayed correctly. Colored files are drawn as I expected with the macro which I send in last e-mail.
I used 'convert' (image magick) and GraphicConverter.app to create PNGs.

Some of gray scale PNGs generates vm_allocate error. And some PNGs are drawn but all gray scale color is drawn as black.

The attached is ROOT splash image converted to gray scale. It causes vm_allocate error.

Please try gray scale PNGs on your machine.

Sincerely,
