|
TTimeIntervalMicroSeconds iDelay;
The delay in microseconds before displaying the next frame.
TUint32 iFlags;
Frame information flags. A combination of the values contained in the TFrameInfoFlags enum.
TSize iOverallSizeInPixels;
The size of the frame. A frame can occupy a rectangle within the overall image. In this case, the frame size is less than the overall image size. For a GIF image, the following applies: For the first frame of the image, iOverallSizeInPixels will be the greater of the logical screen size and the size of the first frame. The logical screen size is defined in the logical screen descriptor block of the GIF image. If the GIF is animated it will contain a set of frames. The first frame will be full size but subsequent frames are sub-frames and iOverallSizeInPixels may differ for each sub-frame.
TSize iFrameSizeInPixels;
The size of frame in pixels
