97e97bccab Everywhere: Make ByteBuffer::{create_*,copy}() OOM-safe 2021-09-06 01:53:26 +02:00

3a9f00c59b Everywhere: Use OOM-safe ByteBuffer APIs where possible 
If we can easily communicate failure, let's avoid asserting and report
failure instead.

079dec11d3 LibGfx: Fix writing PNG headers on x86_64 
m_data.size() returns a size_t which is a 64-bit type on x86_64. This
resulted in us incorrectly using zero in the PNG header.

d1028f8aed LibGfx: Use clear_with capacity instead of clear in PNGWriter 
Same vector was cleared up and filled in continuously.

b70f2b00a3 LibGfx: Store the size of the chunk from start in PNGWriter 
Before this change PNGWriter::add_chunk used to make a copy of
PNGChunk's ByteBuffer to prepend the size of the data.
With this change, 4-byte space is saved from the beginning and written
at the end of the operation. Avoiding this copy yields significant
speed up.

97859aaff1 LibGfx: Use ByteBuffer instead of Vector<u8> in PNGWriter 
This is the first step towards reducing the number of copies in
PNGWriter by switching to ByteBuffer as underlying storage.

dc65f54c06 AK: Rename Vector::append(Vector) => Vector::extend(Vector) 
Let's make it a bit more clear when we're appending the elements from
one vector to the end of another vector.

6793574003 LibGfx: Improve PNG encoder API somewhat 
This is still far from ideal, but let's at least make it take a
Gfx::Bitmap const&.

a1d7739607 LibGfx: adding a very simple PNG writer 
With this patch it is possible to create PNG files. Only minimal options
are supported. The PNG is created with one big IDAT chunk containing
only non-compressible DEFLATE blocks.
