Gain a 15-30% speed boost by sacrificing rendering quality.
Installation
- Add
<add name="SpeedOrQuality" />to the<plugins>section.
Usage
Add &speed=value to any image URL.
Value chart
- 0 - Highest quality
- 1 - High quality bilinear, but with low quality pixel offset, smoothing, composing, and compositing quality.
- 2 - Low quality bilinear
- 3 - GetThumbnailImage() is used. This can produce extremely bad (but instant) results when an image has an embedded EXIF thumbnail (most cameras embed these).
Notes
Resizing is usually the least expensive part of image resizing - jpeg decoding and encoding take most of the time. This plugin can sometimes speed up resizing by 1.5-3x (or more if there is a thumbnail image and you are using &speed=3), but it probably doesn't matter much - the overall savings are likely less than 20%.
This plugin (SpeedOrQuality (v3.1+)) is part of the Essential edition
Where is the plugins section?
The <plugins> section is located in Web.config, and is nested inside the <resizer> element, which is nested inside <configuration>. For examples, see this sample Web.config file.
Where can I find the dll?
We prefer that you install via NuGet, but you can also find the plugin DLL files in the /dlls/release folder of your download.
How do I typically install a plugin via Web.Config?
- In Visual Studio, right click on your project and choose "Add reference". Browse to the plugin DLL and click "OK".
- In the <plugins> section of Web.config, insert <add name="PluginName" />
- Look at the plugin documentation to see what configuration options (if any) are available.
