Bindings for stb_image.c.
In the working directory:
npm install
object pykstbi.loadFromMemory(Buffer buffer, int req_comp=0);
Loads an image from memory. Paletted PNG, BMP, GIF and PIC images are automatically depalettized.
Parameters:
- buffer
- A buffer containing the image file data.
- req_comp
Number of components N in the decoded image data.
An output image with N components has the following components interleaved in this order in each pixel:
N Components 1 grey 2 grey, alpha 3 red, green, blue 4 red, green, blue, alpha
On success, returns the following object:
{ Buffer data, int width, int height, int comp }
where:
- data
- A buffer consisting of image pixel data of height scanlines of width pixels, with each pixel consisting of N interleaved 8-bit components, where N is req_comp if req_comp is non-zero, and comp otherwise. The first pixel in this buffer is the top-left-most of the image. There is no padding between image scanlines or between pixels.
- width
- The width of the image, in pixels.
- height
- The height of the image, in pixels.
- comp
- The number of components pixels in data will have if req_comp is 0.
On failure, returns null.
