Nils Dagsson Moskopp	7b94fc026d	Allow to specify color format	2022-05-16 02:48:51 +02:00
Nils Dagsson Moskopp	fa23775bf9	Measure pixel_depth in bits everywhere	2022-05-16 01:54:21 +02:00
Nils Dagsson Moskopp	36ee45ebe3	Add RGBA support (only RAW encoding)	2022-05-16 01:39:33 +02:00
Nils Dagsson Moskopp	2112637faf	Use HSP for RGB-to-BW8 conversion	2022-05-15 19:58:19 +02:00
Nils Dagsson Moskopp	5b79bc6fb7	Set default encoding to R8G8B8 RAW ... This the most trivial RGB encoding the encoder supports. Setting it prevents a crash related to BW8 only supporting RAW encoding.	2022-05-15 19:31:24 +02:00
Nils Dagsson Moskopp	759b0a188f	Allow saving R8G8B8 images as BW8	2022-05-15 19:23:26 +02:00
Nils Dagsson Moskopp	376b6404b2	Allow RAW or RLE encoding for true-color images	2022-05-15 15:56:18 +02:00
Nils Dagsson Moskopp	9bd1702d60	Encode image only when saving it to a file	2022-05-15 14:58:12 +02:00
Nils Dagsson Moskopp	25b7b30945	Allow encoding grayscale images as BW8	2022-05-14 22:41:52 +02:00
Nils Dagsson Moskopp	9af0719df8	Allow encoding RGB images as B8G8R8	2022-05-14 21:56:42 +02:00
Nils Dagsson Moskopp	1b48c3f539	Use raw packets in RLE compression in tga_encoder	2022-05-14 21:52:08 +02:00
Nils Dagsson Moskopp	13552f16f2	Reduce TGA filesize by 25% by using 16-bit colors	2022-05-14 21:52:07 +02:00
Nils Dagsson Moskopp	adb8e45d67	Fix TGA file writing on Windows ... Before this patch, the tga_encoder mod would write corrupted TGA files on Windows: Bytes that looked like newlines were replaced by a carriage return and a newline.	2022-05-14 20:21:59 +02:00
Nils Dagsson Moskopp	3f60b5baa6	Speed up TGA encoding by creating fewer strings	2022-05-14 20:21:58 +02:00
