Image alignment

[vfp4ever]

Hello,

I am having some trouble displaying an Image control correctly. I assigned a fixed area for it (300x300 pixel) within a Container, and defined an Image Click method that cycles through a set of files according to a global property (image dimensions vary in both size and orientation). In the Container's Refresh method I wrote:

WITH .MyImage
[indent].Stretch = 0
.Picture = "image1.jpg"
.Stretch = 1
[/indent]
ENDWITH

and all images display the way I want. In the Image Click method I wrote the same assignments, but the Image control "centres" the image within the control itself and prevents me from displaying it aligned as before (e.g. a 300x200 rectangle appears 50 pixel further down). It does so as if Image controls had an internal Alignment property set to Centered (I can see this behaviour setting BorderStyle=1). Resetting Width and Height to 300 or setting a specific Anchor do not help, as they apply to the entire control.

Has anybody any suggestion? In practice, I would like to keep my image starting from the same point and having the same maximum 300-pixel size, no matter how wide or tall images are.


Regards,
Dario

Hello,

If I understand you correctly images are shown fine if run from container click but gets centered if run from image click ?
(I do not understand stretch = 0 / 1)

In image click I would not change stretch but only set .picture and do a refresh.
Does this work ?

You may also have a look here, its a class from tony to make isometric look better, maybe it includes some tricks

Can you upload a sample with some pictures ?

Thanks, Tom


Sorry, I did not do my best to explain the problem. I want my Image control to display pictures of various dimensions at either fixed width and/or height at 300 pixels (e.g. Pic1_1, Pic2_1, ... PicN_1). The Image is part of a Page, on which I also have an OptionGroup to select the source of these pictures (Pic1_1, Pic1_2, ... Pic1_5). As an alternative, I want to click on the Image itself so that it loops through all available sources (_1 to _5 and over again).

Initial display of the Image is fine (see picture on grey background

), OptionGroup selection is fine too (black background

), but when I click on the Image the picture changes relative position as if it was centered within its control (now the frame is clearly visible

).

I will look into the post you suggested, thanks.

Dario

Hello,

now I see.

Does it work if in click y<ou only set .picture and do a refresh() , see above ?

Unfortunately I can only see, as an alternative to the picture centered within the frame, the full picture extending to its natural dimension. That happens when I comment out Stretch or Width/Height assignments. An extra Refresh( ) does notthing. I am afraid I cannot use the Image Click event for this purpose. Thanks anyway, Tom.

Hello,

strange.

What about putting a transparent shape (with same anchor) on top of image and do it in the click of the shape ?

I tried to overimpose a Shape on my Image and manage the Shape.Click( ), but the behaviour does not change. I feel I have to rearrange the underlying container and see whether that causes this oddity, but right now I must postpone further experiments on this issue until a later time.

Thank you very much Tom for your patience, will come back to this thread some time soon and try to analyze this further.
