Image resize (target image format)

[Rodrigo Proenca]

Hi,

I'm using RadEditor for MOSS 2007. After uploading an image through the Image Manager dialog box, I'm resizing it using the embedded Image Editor.

After resizing (I've decreased the image size) and saving the image, I can see that the target image (which Image Editor appends a _thumb in the name, by default) is much bigger than the original one.

In my case, I've uploaded and resized a 103Kb .jpg image. After resized the image size is 3.32MB and it's format is .bmp (bitmap instead of jpeg).

Is there a way to configure the Image Editor so I can set the compression method of the target image (like png, jpeg, etc)?

It does not make sense to have bitmap thumbnails because of the huge size of this type of format.

Thanks in advance.

Rodrigo.

Hello Rodrigo,

The reported behavior is really odd and you are the first to report it. Are you able to reproduce the same behavior in the Default Example of RadEditor?

Is it possible that the format of original image is .bmp and the file is renamed by someone to .jpeg?
Could you please send the original image so that we can test it?

Is there a way to configure the Image Editor so I can set the compression method of the target image (like png, jpeg, etc)? - No, this is not possible currently to change the compression method.

Hi Rumen,

I did some tests and it seems that this issue is happening only in my local environment.

Following are the steps I did to reproduce the issue:

1. Go to the online demo Default Example
2. Open the Image Manager
3. Open the folder Banners 
4. Select the image telerik_140x240_reporting.jpg
5. Click on Image Editor
6. Resize the image (Width: 100px, Height: 171px)
7. Save the resized image

This is the result I've got in the online demo:
Original image
Name: Telerik_140x240_reporting.jpg
Size: 10,260 bytes - 140px - 240px
Image raw format: JPEG

Resized image
telerik_140x240_reporting_thumb.jpg

Size: 26,056 bytes - 100px - 171px
Image raw format: PNG

This is the result I've got in my environment:

Resized image
telerik_140x240_reporting_thumb.jpg

Size: 131,072 bytes - 100px - 171px
Image raw format: BMP

Notice that in the RadEditor that I've installed locally the Image Editor is saving the image in BITMAP format and not in PNG format like the online demo.

The version I've installed is: 2008.3.1314.20

I will try to update the version I've installed and will check if the issue stills occur.

Thanks,

Rodrigo.

Hi Rodrigo,


You are using a quite old version which does not support the modern browsers: IE9 and Firefox6. Please, upgrade to the latest one 2011.2.712 which uses a new and enhanced Image Editor and let us know if the problem still persists.
