Hi,

To Stretch it you need specify Width and Height of Image,

but the snippet still can not work well when the Height and Width attributes have been added, the XAML snippet is

if i delete the Stretch='Fill' part, the tag works well,

when that part is added, the entire XAML will be displayed as pure text on the CXTPButton,

in fact, i just wanna reduce the size of 1.jpg and display it on the CXTPButton control, smaller size without Stretch attribute can only show part of the jpg picture, i wanna show the whole jpg picture as a smaller size.

what can i do, tell me please big master

I have a suggestion.

I have the need to have an attribute value for Stretch that works like this:

If the image size is smaller than or equal to the image element size, the image is NOT stretched.

If the image size is BIGGER than the image element, then it is stretched to be reduced.

Actually I am using code to implement it:


    If imImage.Height > (UserControl.Height \ 15 - 40) Then

      ImageCtl.Stretch = xtpMarkupStretchUniform

    Else

      ImageCtl.Stretch = xtpMarkupStretchNone

    End If

But sometimes we cannot do it, as when using markup.

And there are times where only the height or width of the element is fixed. In these cases the Stretch function may do the comparisons only for this fixed size.

Thanks in advance!

Hi,

Afraid I need some test project to see what you mean.

Hi Oleg! Happy New Year!

Suppose that we have a markup label that has only an Image element on it, like this:

<Image Source='101' Stretch='Something'/>

And that the markup label has a size of 100x100 pixels (square).

I need to have the following behavior for Stretch:

If the image to be shown in the element has a small size (e.g. 50x80) then it does not need to be stretched.

But if the image is greater than the element size (e.g. 120x110) then the control would stretch the image so we can see all of it, redimensioned of course.

And if only one size of the image is greater (e.g. 120x80) then the image would be stretched also, but preserving its native aspect ratio.

I tried the 4 Stretch values (None, Fill, Uniform, UniformToFill) but no one does it.

Here is a sample:

uploads/20100105_092742_StretchTest.rar - 20100105_092742_StretchTest.rar

In the test project the only attribute value that does not stretch a small image is 'None'... And I need one that stretch only the big images, but not the small ones.

By the way, the installers are not creating the links for 2 files on the Documentation folder: "Symbol Reference" and "Markup Guide".

Regards!

FWIW, I agree that this would be a nice feature - maybe Stretch='ShrinkUniform'? The image will only be shrunk (with aspect ratio preservation) if its width or height are greater than the containing element's width/height.

Hi all!

Here is a new suggestion:

To use the Lanczos3 filter to do the stretch of images.

The reason is that the actual stretch is showing the images with a not so clear resolution.

I am showing images of products on the product base, photos of customers on the customers base, etc. and the photos and pictures when stretched are not so good, compared to the same image redimensioned on IrfanView using the Lanczos3 filter.

With Regards!
