Testbed for the proposed changes to class Svg

This app shows the proposed changes to class Svg:

• The Mode button changes how the MemoryCache keys are composed:

  • integral: the new default: it uses the integer destination dimensions, which avoids floating-point rounding errors but makes the image cache behave differently from previous versions of class Svg; in practice, this should not break existing uses of class Svg
  • fixed: this uses only the integer SVG dimensions, resulting in a single cache entry

• The Size button changes the MemoryCache size:

  • standard: the current default == max 10 entries
  • medium: max 50 entries
  • large: max 100 entries
  • huge: max 250 entries
  • unlimited: max entries correspond to the largest representable integer, making the MemoryCache property behave like a Map.

• The Svg button cycles through a few SVGs.

The amount of SvgComponent objects may be adjusted via a slider:

These are a few results with several 'Mode' and 'Size' combinations:

integral/standard:

integral/medium:

integral/large:

integral/huge:

fixed/standard:
