The _glCopyTexImage2D statement copies pixels from the framebuffer into a two-dimensional texture image.
Syntax
- _glCopyTexImage2D GLenum target, GLint level, GLenum internalFormat, GLint x, GLint y, GLsizei width, GLsizei height, GLint border
Parameters
- OpenGL is using its own set of variable types to describe its command parameters.
- Use the following table to find the respective QB64 Variable Types.
OpenGL | C/C++ | QB64 ------------+------------------+---------------------- GLenum | unsigned int | _UNSIGNED LONG GLboolean | unsigned char | _UNSIGNED _BYTE GLbitfield | unsigned int | _UNSIGNED LONG GLbyte | signed char | _BYTE GLshort | short | INTEGER GLint | int | LONG GLsizei | int | LONG GLubyte | unsigned char | _UNSIGNED _BYTE GLushort | unsigned short | _UNSIGNED INTEGER GLuint | unsigned int | _UNSIGNED LONG GLfloat | float | SINGLE GLclampf | float | SINGLE GLdouble | double | DOUBLE GLclampd | double | DOUBLE GLvoid | void | no parameters used |
Description
- OpenGL's documentation is available in several places, so we won't reproduce it here for another time.
- The full description for this command can be found at Microsoft Docs and is also valid for QB64 usage.
