Terminology

widthStride

Stride of each line of pixels, also the width result from alignment of the input image. 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:

• VPC: Restrictions on Image Formats, Width and Height Alignment, and Buffers
• JPEGD: JPEGD Functions and Restrictions
• JPEGE: JPEGE Functions and Restrictions
• PNGD: Functions and Restrictions
• VDEC: VDEC Functions and Restrictions
• VENC: VENC Functions and Restrictions

heightStride

Number of pixel lines in the buffer, indicating the height of the input image after alignment.

The requirements on heightStride vary according to different functions. For details, see the following restrictions:

• VPC: Restrictions on Image Formats, Width and Height Alignment, and Buffers
• JPEGD: JPEGD Functions and Restrictions
• JPEGE: JPEGE Functions and Restrictions
• PNGD: Functions and Restrictions
• VDEC: VDEC Functions and Restrictions
• VENC: VENC Functions and Restrictions

Crop ROI

ROI selected to crop. The cropping start coordinates are not restricted to odd or even numbers.

The minimum resolution of the crop ROI is 10 x 6, and the maximum resolution is 8192 x 8192.

For restrictions on the crop ROI, see Restrictions on Image Cropping and Pasting.

Paste ROI

ROI selected 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.

Top/Left offset

Position of the crop ROI or paste ROI based on the configured top offset, left offset, and width and height of the crop ROI or paste ROI.
