public final class IMGReadFormat extends java.lang.Object
Native bindings to the IMG_read_format extension.This extension is intended to supplement the GL_OES_read_format extension by adding support for more format/type combinations to be used when calling ReadPixels. ReadPixels currently accepts one fixed format/type combination (format RGBA and type UNSIGNED_BYTE) for portability, and an implementation specific format/type combination queried using the tokens IMPLEMENTATION_COLOR_READ_FORMAT_OES and IMPLEMENTATION_COLOR_READ_TYPE_OES (GL_OES_read_format extension). This extension adds the following format/type combinations to those currently allowed to be returned by GetIntegerV:
format type ------ ---- BGRA_IMG UNSIGNED_BYTE BGRA_IMG UNSIGNED_SHORT_4_4_4_4_REV_IMG
E.g. Calling GetIntegerv with a
pname
parameter of IMPLEMENTATION_COLOR_READ_FORMAT_OES can now return BGRA, with the corresponding call to GetIntegerv using apname
parameter of IMPLEMENTATION_COLOR_READ_TYPE_OES returning UNSIGNED_BYTE;
