nn::jpeg::CTR::JpegMpDecoder::GetLastOutputBufferWidth Member Function

#include <nn/jpeg.h>

u32 GetLastOutputBufferWidth() const;

None.

The width (in pixels) of the output image buffer.
If the output image buffer width was specified with the SetOutputBufferWidth function before decoding, this function returns either that specified value (rounded down to match the pixel format) or the image width (rounded up to match the pixel format), whichever is greater. Returns 0 on failure.

Gets the width of the output image buffer where an image was decoded immediately previously.

If the image was not decoded immediately previously but only had its EXIF information extracted, you cannot call this function. (In that case the return value is undefined.)
