stbi #

Description:

stbi is a thin wrapper around stb's stb_image.h, which in turn is "a public domain image loader" for popular graphics image file formats.

fn load(path string, params LoadParams) !Image

load load an image from a path

fn load_from_memory(buf &u8, bufsize int, params LoadParams) !Image

load_from_memory load an image from a memory buffer

fn resize_uint8(img &Image, output_w int, output_h int) !Image

resize_uint8 resizes img to dimensions of output_w and output_h

fn set_flip_vertically_on_load(val bool)

fn set_flip_vertically_on_write(val bool)

fn set_png_compression_level(level int)

set_png_compression_level set the PNG compression level during the writing process defaults to 8; set to higher for more compression

fn stbi_write_bmp(path string, w int, h int, comp int, buf &u8) !

stbi_write_png write on path a BMP file

fn stbi_write_jpg(path string, w int, h int, comp int, buf &u8, quality int) !

stbi_write_png write on path a JPG file quality select the compression quality of the JPG quality is between 1 and 100. Higher quality looks better but results in a bigger image.

fn stbi_write_png(path string, w int, h int, comp int, buf &u8, row_stride_in_bytes int) !

stbi_write_png write on path a PNG file row_stride_in_bytes is usually equal to: w * comp

fn stbi_write_tga(path string, w int, h int, comp int, buf &u8) !

stbi_write_png write on path a TGA file

fn write_force_png_filter(level int)

write_force_png_filter defaults to -1; set to 0..5 to force a filter mode the filter algorithms that can be applied before compression. The purpose of these filters is to prepare the image data for optimum compression. Type Name

0 None 1 Sub 2 Up 3 Average 4 Paeth

fn write_tga_with_rle(flag bool)

stbi_write_tga_with_rle enable/disable the TGA RLE during the writing process defaults to true; set to false to disable RLE in tga

	// If set to 0 stbi will figure out the correct number of channels
	desired_channels int = C.STBI_rgb_alpha
