I tried to bind a bitmap texture. This bitmap is BGR format, and I'm trying to use glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_BGR, GL_UNSIGNED_BYTE, data), but during compile, error: 'GL_BGR' undeclared appears.

I checked <GLES2/gl2.h> and <GLES2/gl2ext.h>, but there isn't any GL_BGR . Is there any way to upload BGR format?

Unfortunately OpenGL ES2.0 does not support BGR texture formats in glTexImage2D.

format determines the composition of each element in data. It can assume one of these symbolic values:

  • GL_ALPHA
  • GL_RGB
  • GL_RGBA
  • GL_LUMINANCE
  • GL_LUMINANCE_ALPHA
