WebJimp enables low-level manipulation of images in memory through the bitmap property of each Jimp object: image.bitmap.data; // a Buffer of the raw bitmap data image.bitmap.width; // the width of the image image.bitmap.height; // the height of the image. This data can be manipulated directly, but remember: garbage in, garbage out. WebApr 11, 2024 · Bitmap (width: int, height: int, value_count: int) Stores values of a certain size in a 2D array. Bitmaps can be treated as read-only buffers. If the number of bits in a pixel is 8, 16, or 32; and the number of bytes per row is a multiple of 4, then the resulting memoryview will correspond directly with the bitmap’s contents. ions navy
