示例1: gen_gray_strip
function gen_gray_strip() {
const gf = new omggif.GifWriter(buf, 256, 1);
const palette = [];
const indices = [];
for (let i = 0; i < 256; ++i) {
palette.push((i << 16) | (i << 8) | i);
indices.push(i);
}
gf.addFrame(0, 0, 256, 1, indices, { palette });
return gf.end();
}示例2: gen_anim
function gen_anim() {
// The loop parameter is the number of times to loop, or 0 for forever.
// A value of 1 will play twice (first time, and then one loop time).
// To play only once do not specify loop or pass null.
const gf = new omggif.GifWriter(buf, 2, 2, { loop: 1 });
gf.addFrame(0, 0, 2, 2, [0, 1, 1, 0], { palette: [0xff0000, 0x0000ff] });
gf.addFrame(0, 0, 2, 2, [1, 0, 0, 1], {
palette: [0xff0000, 0x0000ff],
delay: 10,
}); // Delay in hundredths of a sec (100 = 1s).
return gf.end();
}示例3: gen_block256
// with lzw block of 256.
// see: https://github.com/deanm/omggif/issues/5
function gen_block256() {
const width = 4840;
const gf = new omggif.GifWriter(buf, width, 1, {
palette: [0x000000, 0x000000, 0x000000, 0x000000, 0x000000, 0x000000, 0x000000, 0x000000],
});
const stream = Array(width);
for (let i = 0; i < width; ++i) stream[i] = i & 0x7;
gf.addFrame(0, 0, width, 1, stream, { transparent: 0 });
const data = buf.slice(0, gf.end());
// Make sure it decodes.
const gr = new omggif.GifReader(data);
const frameInfo = gr.frameInfo(0);
return frameInfo;
}示例4: gen_color_strip
// More than 8-bit color (via tiling of several frames). Browsers seem to
// treat this as an animation though, with an enforced minimum time between
// frames which makes it animated instead of the intended static image.
function gen_color_strip() {
const gf = new omggif.GifWriter(buf, 256, 256, {
palette: [0x000000, 0xff0000],
background: 1,
});
const indices = [];
for (let i = 0; i < 256; ++i) indices.push(i);
for (let j = 0; j < 256; ++j) {
const palette = [];
for (let i = 0; i < 256; ++i) palette.push((j << 16) | (i << 8) | i);
gf.addFrame(0, j, 256, 1, indices, { palette, disposal: 1 });
}
return gf.end();
}示例5: gen_static_global
function gen_static_global() {
const gf = new omggif.GifWriter(buf, 2, 2, { palette: [0xff0000, 0x0000ff] });
gf.addFrame(0, 0, 2, 2, [0, 1, 1, 0]);
return gf.end();
}示例6: gen_empty_white
// 1x1 white, generates the same as Google's 35 byte __utm.gif, except for some
// reason that I'm not sure of they set their background index to 255.
function gen_empty_white() {
const gf = new omggif.GifWriter(buf, 1, 1, { palette: [0xffffff, 0x000000] });
gf.addFrame(0, 0, 1, 1, [0]);
return gf.end();
