Avoid Performance Degradation when Drawing over Compressed Images

Avoid Performance Degradation when Drawing over Compressed Images

There are times when you want to perform extremely extensive graphic operations on a compressed image. When Aspose.Imaging has to compress and decompress images on the fly, performance degradation may occur. Drawing over compressed images may also carry a performance penalty.

Solution

To avoid performance degradation, we recommend that you convert the image to an uncompressed, or raw, format before performing graphic operations.

Using File Path

In the example that follows, a Png image is converted to another Png and saved to disk. The image is then loaded back before graphic operations are performed on it. The same technique applies for BMP and GIF files.

Using a Stream Object

The following code snippet shows you how to Png image is converted to another Png image and saved to disk using MemoryStream.
