texSubImage2D

public static void texSubImage2D(com.badlogic.gdx.graphics.Texture tex,
 int mipmapLevel,
 int x,
 int y,
 int width,
 int height,
 int glFormat,
 int glType,
 Buffer pixels)

Draw a two-dimensional buffer to a texture using glTexSubImage2D().

Parameters:

tex - The texture.

mipmapLevel - Specifies the level-of-detail number. Level 0 is the base image level. Level n is the nth mipmap reduction image.

x - Specifies a texel offset in the x direction within the texture array.

y - Specifies a texel offset in the y direction within the texture array.

width - Specifies the width of the texture subimage.

height - Specifies the height of the texture subimage.

glFormat - Specifies the format of the pixel data. The following symbolic values are accepted: GL_RED, GL_RG, GL_RGB, GL_BGR, GL_RGBA, GL_BGRA, GL_DEPTH_COMPONENT, and GL_STENCIL_INDEX.

glType - Specifies the data type of the pixel data. The following symbolic values are accepted: GL_UNSIGNED_BYTE, GL_BYTE, GL_UNSIGNED_SHORT, GL_SHORT, GL_UNSIGNED_INT, GL_INT, GL_FLOAT, GL_UNSIGNED_BYTE_3_3_2, GL_UNSIGNED_BYTE_2_3_3_REV, GL_UNSIGNED_SHORT_5_6_5, GL_UNSIGNED_SHORT_5_6_5_REV, GL_UNSIGNED_SHORT_4_4_4_4, GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1, GL_UNSIGNED_SHORT_1_5_5_5_REV, GL_UNSIGNED_INT_8_8_8_8, GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, and GL_UNSIGNED_INT_2_10_10_10_REV.

pixels - Specifies a pointer to the image data in memory as a Buffer.
