From b90fd355150a0f56e368bb33619459b19ec92bee Mon Sep 17 00:00:00 2001 From: Vas Crabb Date: Thu, 8 Oct 2020 02:04:31 +1100 Subject: Various improvements to image file handling: Moved MS DIB parser out of ICO file reader and made it available for artwork and layout images. Added more efficient I/O and better error checking for JPEG file loading (MAME will no longer exit immediately on a bad JPEG file). Made caller responsible for opening files for loading images, to avoid decompressing images used in ZIP/7z artwork multiple times. Added support for JPEG and Windows DIB to picture_image_device. Added support for SVG image files in external artwork. Added support for using I/O port value for animation state and masking animation state values. Made bounds elements more flexible in layouts. Reworked headers to reduce dependencies. Updated layout file format documentation. --- src/lib/util/msdib.h | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 src/lib/util/msdib.h (limited to 'src/lib/util/msdib.h') diff --git a/src/lib/util/msdib.h b/src/lib/util/msdib.h new file mode 100644 index 00000000000..54767e216fb --- /dev/null +++ b/src/lib/util/msdib.h @@ -0,0 +1,46 @@ +// license:BSD-3-Clause +// copyright-holders:Vas Crabb +/*************************************************************************** + + msdib.h + + Microsoft Device-Independent Bitmap file loading. + +***************************************************************************/ +#ifndef MAME_LIB_UTIL_MSDIB_H +#define MAME_LIB_UTIL_MSDIB_H + +#pragma once + +#include "bitmap.h" +#include "corefile.h" +#include "osdcore.h" + +#include + + +namespace util { + +/*************************************************************************** + CONSTANTS +***************************************************************************/ + +// Error types +enum class msdib_error +{ + NONE, + OUT_OF_MEMORY, + FILE_ERROR, + BAD_SIGNATURE, + FILE_TRUNCATED, + FILE_CORRUPT, + UNSUPPORTED_FORMAT +}; + +msdib_error msdib_verify_header(core_file &fp); +msdib_error msdib_read_bitmap(core_file &fp, bitmap_argb32 &bitmap); +msdib_error msdib_read_bitmap_data(core_file &fp, bitmap_argb32 &bitmap, std::uint32_t length, std::uint32_t dirheight = 0U); + +} // namespace util + +#endif // MAME_LIB_UTIL_MSDIB_H -- cgit v1.2.3-70-g09d2
