Terminology

Description |
|---|---|
widthStride |
Stride of each line of pixels, also the width result from alignment of the input and output images. widthStride of an RGB image is calculated differently from that of a YUV image. |
heightStride |
Number of pixel lines in the buffer, indicating the height of the input and output images after alignment. |
Top/Bottom/Left/Right offset |
Used to configure the top offset, bottom offset, left offset, and right offset for the following purposes: (1) Specify the position of the crop ROI or paste ROI. (2) Specify the width and height of the crop ROI or paste ROI by using the following formulas: Right offset – Left offset + 1 = Width; Bottom offset – Top offset + 1 = Height. |
Crop ROI |
ROI cropped from an input image. The crop ROI must not be larger than the input image. |
Paste ROI |
ROI selected in the canvas to paste. |
Non-8K |
Input image resolution ranging from 10 x 6 to 4096 x 4096. In the non-8K scenario, the width stride and height stride of the input image meet the following requirements: (Width stride/Coefficient) ∈ [32, 4096], and Height stride ∈ [6, 4096]. The coefficient is related to the input image format.

8K |
Input image resolution ranging from 4096 to 8192 (excluding 4096). |
