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. The requirements on widthStride vary according to different functions. For details, see the following restrictions: |
heightStride |
Number of pixel lines in the buffer, indicating the height of the input and output images after alignment. The requirements on heightStride vary according to different functions. For details, see the following restrictions: |
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. For details, see Figure 1. |
Crop ROI |
ROI selected to crop. The minimum resolution is 10 x 6, and the maximum resolution is 4096 x 4096. For restrictions on the crop ROI, see Restrictions on Image Cropping and Pasting. |
Paste ROI |
ROI selected in the canvas to paste. The minimum resolution is 10 x 6, and the maximum resolution is 4096 x 4096. For restrictions on the paste ROI, see Restrictions on Image Cropping and Pasting. |
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). In the 8K scenario, the width stride and height stride of the input image meet the following requirements: |
