e0a32a701b #63 make cache of parsed system fonts static and read the whole file up-front rather than using a filestream 2019-08-19 20:09:07 +01:00

0fa3b27ad3 #47 improve flate filter performance by streaming all data in single operation 
also improves page constructor performance by removing linq and invoking stringbuilder directly. removes page rotation overhead by skipping multiplication for non-rotated pages and using cached transformation matrices for rotations. removes linq from filter provider and shares instances of filter types.

11b244eda1 remove thread-unsafe stringbuilder access from adobe font metrics parser 
this also hoists the char arrays used for string splits since these will be allocated per call if declared inline

d98b8b43c1 small performance tweaks and remove package license expression 
package license url is deprecated in favour of package license expression but nuget doesn't seem to support expressions properly for published packages yet so we'll keep the deprecated url for the time being. having both url and expression causes the build to fail.

small obvious performance improvements for file header passing and getting the encoding information using the existing reverse name to code map.

364bd25fa8 #48 add handling of inline image data to pdf content parsing 
an inline image in a pdf content stream starts with the bi tag, then id declares the start of image data and ei the end. attempting to parse the bytes after the id tag as usual resulted in errors. this change adds special case handling for inline images.
