Re: [gl4java-usergroup] Problem reading frame buffer.

[Sven G. <sgo...@ja...>]

Dear Erwin,

to generate a snapshot for GLMame32,
I used to setup the pixel packing modes, like this:

  glPixelStorei(GL_PACK_ALIGNMENT, 1); /* byte alignment - I guess THIS
IS THE VALUE FOR YOU, default is 4 */
  glPixelStorei(GL_PACK_ROW_LENGTH, width); /* pixels in a row */
  glPixelStorei(GL_PACK_LSB_FIRST, GL_TRUE); /* Intel data :-) */

  glReadPixels(0,0, width, height,
                           GL_RGB, GL_UNSIGNED_BYTE,
                           pixels);

  glPixelStorei(GL_PACK_ALIGNMENT,4); /* reset the data */
  glPixelStorei(GL_PACK_ROW_LENGTH, 0);

I hope this will help.

Sven
