About TiffAppendPageFromGdPictureImage method

[Eric]

I use TiffCreateMultiPageFromGdPictureImage methd to create a multipage in memory,and use TiffAppendPageFromGdPictureImage method to add page,then i find the speed become very slow.

So I use log4net to record some information like process time,then I find something.

The spend time of TiffAppendPageFromGdPictureImage is below

first time：00:00:00.60
2：00:00:00.75
3：00:00:00.90
4：00:00:01.04
5：00:00:01.19
6：00:00:01.35
7：00:00:01.50
8：00:00:01.65
9：00:00:01.79
10.00:00:01.94

11.00:00:02.09
12.00:00:02.24
13.00:00:02.39
14.00:00:02.53
15.00:00:02.70
16.00:00:02.86
17.00:00:03.00
18.00:00:03.15
19.00:00:03.29
20.00:00:03.44

You can find the multipage's page become more,and the TiffAppendPageFromGdPictureImage method spend time more too.

How to improve this question.
