Member Function Documentation

bool vtImage::Read (  const char *  fname, bool  bAllowCache = true, bool   progress_callback(int) = NULL )

all the way to the app.

void vtImage::Set16Bit (  bool  bFlag  )

Call this method to tell vtlib that you want it to use a 16-bit texture (internal memory format) to be sent to the graphics card.

bool vtImage::WriteJPEG (  const char *  fname, int  quality = 99, bool   progress_callback(int) = NULL )

Write this image to a JPEG file. Quality setting is the same as libjpeg, in the range of 0..100. 99 is a typically useful quality setting.
