Member Function Documentation

◆ actualUploadProc()

TPureBool PureTexture::PureTextureImpl::actualUploadProc	(	GLint	internalfmt,
		GLenum	glTexFormat )

private

This contains the actual pixel upload code.

The following properties of the given texture object should be set properly before calling this method:

nMIPmapCount: should be a positive value; if 1, no MIP maps will be generated, otherwise MIP maps will be generated.
nWidth, nHeight: although not used by this method (because the method uses sizes of the given Image), it is recommended to be already defined.

Parameters

internalfmt	OpenGL target internal format for storing texture in VRAM. Suitable can be selected by getTargetInternalFormat().
glTexFormat	OpenGL source format, how to interpret input. Suitable can be selected by getTransformedSourceFormat().

Returns: True on success, false on error.

Definition at line 612 of file PureTexture.cpp.

◆ DescribeTexFormatAndSize()

void PureTexture::PureTextureImpl::DescribeTexFormatAndSize ( GLint internalfmt )

private

Updates texFormat and nSize members based on given internalfmt.

Internal format (texFormat) and used texture memory (nSize) will be updated based on given internalfmt.

This is needed so that real size and compression is queried from OpenGL after the texture has been uploaded. Not doing much when software rendering is selected.

◆ getTransformedSourceFormat()

GLenum PureTexture::PureTextureImpl::getTransformedSourceFormat ( TPURE_PIXEL_COMPONENT_ORDER oldco )

private

Transforms to a proper pixel component order and returns the source format.

Transforms to a proper pixel component order and returns the proper OpenGL source format.

For example, if the image's color component order is PURE_BGR and OpenGL driver supports that format natively, no transform is needed, respective OpenGL source format will be returned quickly. However if driver doesn't have support for that, then color component order first gets transformed to PURE_RGB, and then respective OpenGL source format will be returned.

Returns: OpenGL source format enum. GL_INVALID_ENUM in case of error.
