TMCCJPEGEncGetOutputSize

Syntax

#include <revolution/tmcc_jpeg.h>

s32 TMCCJPEGEncGetOutputSize(
        void *pWorkArea,
        void *pTex,
        u16 srcWidth,
        u16 srcHeight,
        GXTexFmt texFormat,
        u32 *poutputSize,
        u32 QFactor
);

Arguments

*pWorkArea Configure the starting address of the work area.
*pTex Configure the starting address of the input texture data.
srcWidth Specify the effective image width of the input texture.
(When the texture size does not match the effective image region, fill the remaining parts with dummy data. A TMCC_JPEG_OPT_ERR error code is returned for input that exceeds the range of 1 to 65,535.）
srcHeight Specify the effective image height of the input texture.
(When the texture size does not match the effective image region, fill the remaining parts with dummy data. A TMCC_JPEG_OPT_ERR error code is returned for input that exceeds the range of 1 to 65,535.）
texFormat Specify the texture format.
(A TMCC_JPEG_TEXT_ERR error code will be returned for input that is neither GX_TF_RGB565 nor GX_TF_RGBA8.）
*poutputSize Size that is possible to output, given QFactor.
QFactor Specify the quality factor.
(A TMCC_JPEG_OPT_ERR error code will be returned for input that exceeds the range of 1 to 500.）

Return Values

0 Function completed successfully.
Negative Abnormal exit (error code).

Description

Determines the actual output size for a given image quality factor. Returns the actual output size (*poutputSize) when the input texture image data is compressed by the specified image quality factor (QFactor).
