Hi,
We use the control to loading different type of the file types. we have problem with raster files.
the problem is sometimes when the control loading a raster files and we start zooming in/out some of the tiles remain blurry, as you can see in the attachment.
I'll be grateful if you help me to solve this.

Hi Ben,
Thanks for your post. As I can see from the screen shot, the problem does exist, but I’m not sure about the reason why this problem occurs without further information, there might be at least three kinds of probabilities, which are, maybe it’s caused by how we consume the raster file (within MapSuiteCore), or it has something to do with how we display the tiles (within WPFDesktopEdition), or even a problem with the original raster file.
We really appreciate that if you’re willing to provide us further information ,such as ,the original raster file, which layer you’re using exactly in your case, the version of WpfDesktopEdition, so that we may be able to recreate your problem and fix the problem for you.
Thank you very much.
James
Many thanks for your answer,
I’m using on of your latest version of WpfDesktopEdition(4.5.65.0).
the problem occurs in different raster files and different part of the raster files too. in addition the place of bluey is not always same place.
Raster files that I’m using have big sizes (more than 5 meg), but if you want I can mail one of them to support@yhinkgeo.com.

It may not be related to the raster itself but with the zooming, as in the post: gis.thinkgeo.com/Support/DiscussionForums/tabid/143/aff/39/aft/8683/afv/topic/Default.aspx#23336
Carlos & Ben,
Thanks for your posts,
According to our investigations, we cannot reproduce your problem correctly, the stretched images can be cleared correctly and overrided by the real images, I just have a question to ask you, did you override the DrawCore method in your application? In order to resolve this problem correctly can you provide us a simple sample to reproduce this problem better?
Thanks,
Scott,
Hi,
I create a sample project and sent it with sample data to support@thinkgeo.com.
the problem mostly occur on top/left edge of the Raster files.

Ben
Ben,
We got the Raster.zip from support but unfortunately it can not be unzipped, I have contacted our support to check it. Meanwhile, if you have time, could you send data to forumsupport@thinkgeo.com directly.
When we get the correct data, we will start to work on this issue asap.
Thanks,
James
Ben,
We have reproduced your problem exactly and we found out a workaround for your tiff image file, please get the attachment and put your tif file to the specify location, the tif file is not in the attachment because of the limitation problem on this forum. For this solution, there are not any streched image issue.
If you still have any other questions please let us know,
Thanks,
Scott,
