woutware	e7f125d5fe	Processed Scott's review comment.	8 years ago
woutware	b21afaac88	Add Image and ImageFrame constructors that take a clear color as parameter. This is good for performance because this avoids first needing to clear the buffer with zeroes.	8 years ago

woutware	88fd0674b9	Processed review comments and did similar refactoring to the PNG decoding.	8 years ago
woutware	8fc424a38a	Minor performance refactorings. Moved the division out of the loop, division is expensive.	8 years ago

woutware	7278f5b223	Removed some overhead in the Bgra32.ToVector4 and PackFromVector4 methods. It's now also more inline with the Rgba32 implementation.	8 years ago
popow	041aea9fcb	added parameter metadataOnly to InitializeDerivedData: If true, memory allocation will not be done	8 years ago
woutware	c7e6d19cc1	Performance improvements. Ditched the use of modulo (%). Modulo is slow, and if you use it to just get the lower 8 bits (1 byte), you can just directly cast to byte. Also moved one if < out of the loop for speed. The less branching the better. Similarly replaced an if < 128 by cast to sbyte and taking its abs value. Performance gain in writing to PNG file seems to be roughly 20% (release mode, 1000x1000 bitmap). In ImageFramesCollectionTests I've set the culture to en-US to ensure getting english exception texts.	8 years ago

Unknown	fdfef1617a	FIX bug in BrushApplicator when applying BlendPercentage thanks @tocsoft for investigation and finding the bug. He proposed to just replace < by <= in line 78, but that would only shift the problem to values > 1. Those values should not be used from a semantic point, but it's not forbidden in a float value. My fix here keeps the <, but adds an else path that uses the original value from scanline[i]. This adds an else to the code (which technically adds a jump after the then-part), but omits the multiplication. The simple solution @tocsoft proposed might be faster, but should be preferred if and only if BlendPercentage can be guaranteed to be <=1.	8 years ago
