Cristobal,

sorry, I still don't understand your problem.

Sorry for my English

Cristobal,

what I understood is that you want to resize the TImage control so it gets the same size of the image, right? Now, can you build a little sample showing the exact problem?

EMG

[cnavarro]

Sí
En el ejemplo inicial que tu has puesto y en los que yo he añadido el tamaño del control no coincide con el tamaño de la imagen que se quiere mostrar
Yo puedo hacer que el tamaño del control sea igual al tamaño de la imagen si en el ON INIT del DIALOG añado el oImage:SetSize( .... ), pero el control deberia dibujarse con el mismo tamaño que la imagen que quieres cargar.

yes
In the initial example that you have set and in which I added the size of the control does not match the size of the image to be shown
I can make the size of the check is equal to the size of the image if the ON INIT of DIALOG add the oImage: SetSize (....), but the control should be drawn with the same size as the image you want to upload.

Cristobal,

this solution is included : a preview of the exported image.
I'm showing a little 3D-effect at the imageborder, but it can be flat.
Like You can see, it is the same size, embedded inside the dialog.

I got extended test as well, in case You want to show ALPABLENDED bmp's

Code: Select all  Expand view

STATIC FUNCTION SHOW_IMGAGE(oDlg, cDestFile)
LOCAL oDlg1, oTest, nImgWidth, nImgHeight

DEFINE IMAGE oTest FILENAME c_Path1 + cDestFile

// needed for dialog-size
nImgWidth := oTest:nWidth
nImgHeight := oTest:nHeight

// is used, to make it possible, to show a image RESIZED
oBrush := TBrush():new( ,,,, ResizeBmp( oTest:hBitmap, nImgWidth, nImgHeight, .T. ) )
oTest:End()

DEFINE DIALOG oDlg1 TITLE "EXPORT-IMAGE" FROM 0, 0 TO nImgHeight, nImgWidth PIXEL

ACTIVATE DIALOG oDlg1 CENTER ;
ON INIT oDlg1:SetBrush( oBrush )

oBrush:End()

RETURN( NIL )
 

Best regards

Cristobal,

but the control should be drawn with the same size as the image you want to upload.

So do you want an AUTORESIZE clause for TImage (or sort of)? If yes, you have to ask to Antonio, sorry.

Thanks for your interest
AUTORESIZE clause?
Well, it may be, I want to load an image of 150x100, for example, and the control that contains it also has the size 150x100, nothing more.

Gracias por tu interes
Claúsula AUTORESIZE?
Bien, puede ser, yo quiero cargar una imagen de 150x100, por ejemplo, y que el control que lo contiene tenga también ese tamaño 150x100, nada mas.

And please, why can't you use SetSize()? I still don't understand, I'm very sorry...

Sure I'll use SetSize, I was just researching and asking if anyone knew that the monitoring was twice the size of the image, or was I knew not use the IMAGE command.
And also, by investigating the size of the image you get in C has 4 pixels less in width and height than that obtained in FWH
Thanks again

Claro que voy a usar SetSize, solo estaba investigando y preguntando si alguien sabia por que el control era doble de tamaño que la imagen, o era que yo no sabia usar el comando IMAGE.
Y tambien, investigaba por que el tamaño de la imagen que obtengo en C tiene 4 pixeles menos en ancho y alto que la que se obtiene en FWH
Gracias otra vez

Cristobal,

Enrico

I already answered: TImage, as any other control, doesn't automatically resize to its content.

And also, by investigating the size of the image you get in C has 4 pixels less in width and height than that obtained in FWH

I can't replicate this behavior, sorry. Can you show me a little sample?

I already knew
But catches my attention that if we give the file to display, and the classe it calculates the size of the image before drawing the control, do not you draw with these dimensions
In other cases I have always understood that it was more complicated to adapt the size of the control to its content.
It's just curiosity.
Prepare an example you can compile

Eso ya lo sabia
Pero me llama la atencion que si le damos el fichero a mostrar, y en la classe él calcula el tamaño de la imagen antes de dibujar el control, por qué no lo dibujaba con esas dimensiones
En otros casos siempre he entendido que era mas complicado adaptar las dimensiones del control a su contenido.
Solo es curiosidad.
Preparo un ejemplo que puedas compilar

Uwe
thanks
I think the edge of the image, may be the problem I have

Uwe
Gracias
Creo que el borde de la imagen, puede ser el problema que tengo

[Enrico Maria Giordano]

Cristobal,

Thank you, I'm curious now.

Cristobal,

1. the image was captured with BORDER
2. You can paint and capture without border
3. or You can adjust the dialog

the screenshot shows a captured image with border and dialog adjusted ( covering the border of the EXPORT-image.
I changed this line inside the posted function, to cover the border of the captured image :

DEFINE DIALOG oDlg1 TITLE "EXPORT-IMAGE" FROM 0, 0 TO nImgHeight - 5 , nImgWidth - 5 PIXEL

( Added some more options )



Best regards
