Adjust a Bmp to a xBrowse-Cell-Grid ?

[ukoenig]

Hello,

is it possible, to fill a xBrowse-Cell complete with aBMP ( like a picture table ) ?
Normally at least one Char is needed.
I think it must be changed inside the class.
I would be nice, xBrowse could be used as a real picture-browser ( no text )

The color resolution of the used / tested imaged from the image-directory is very low.
Is it maybe possible to use JPG- or BMP-files with higher resolutions ?

Possible Cell-Display ?


Inside the Browser it works, but doesn't fill the cell completely.


There was a possible xBrowse-solution, I have done for Silvio to display images on Mouseclick inside a cell.
I can show any Backgrounds and display a Cell-Bmp on top of it.
I want to use something like that inside my own application.
For a graphic-software, I need to show small scanned portraits of students, belonging to a school-class.
With a double-click on a cell, I open a file-list from a directory with all students-pictures to select a picture.
Each class is displayed with a extra browser. For a 3D-effect, I included a xBrowse-Shadow.
The final version will have two folderpages :
1. Page the Browser
2. Page shows Detail-informations of the student of the selected cell.

The first solution ( Silvio )

Hi Uwe

Your project sounds useful for my sons school.
Just a thought...I thought BMP's can be adjusted to fit a frame.
Long time since I experimented with them.
The display of native JPG's would be better though.
I can't help at the moment, maybe someone else can help you.
When you have sorted out the problems please let me know.

Best wishes

Hello Uwe

yes, please try with this columns data lBmpStretch and set "true"
oBrw:aCols[ 1 ]:lBmpStretch := .t.

Is it maybe possible to use JPG- or BMP-files with higher resolutions ?

yes, see my post in spanish forum
viewtopic.php?p=76565#p76565
this explain how paint jpg and other imagen format in xbrowse

With a double-click on a cell, I open a file-list from a directory with all students-pictures to select a picture.

i 'm thinking for other case, i hope have answer soon

Hello Daniel,

I did some tests, but it doesn't work with other formats.
With BMP it is ok. Freeimage is included because i use a JPG-Logo on Main-Screen and that works.
Test.jpg is shown as logo on Screen for a test ( size 50 x 50 ).

hBitmap = FILoadImg( AllTrim( "Test.jpg" ) )

if Upper( cFileExt( cFile ) ) = "BMP"
return ReadBitmap( 0, cFile )
endif

67 nFormat = FIGETFILETYPE( cFile, 0 )

It seems only BMP is accepted.

Hello Daniel,

I didn't include the DLL-functions, because they are defined
in class TIMAGE.prg.
I added them to the test and it works fine now.
But why do we need them to define twice ?
I still have to figure out, to display a Image without text inside a cell.
( a column with only images )
There is a new FREEIMAGE-version I tested with :
new size 2.084.864 / 27.07.2008
It works without problems.

Thank You
Best Regards
Uwe

i think are private function

Hello Daniel,

Your solution works fine. The basics are done, but there is still much to do.
Because in the future, I will work with a database, I added a dynamic-bmp-list.
There will be a "blanc" picture added to the array, if a picture is missing.
Each person will have a picture-number.
The picture-name in the picture-directory will be "Picture" + alltrim((database)->NO)) + ".jpg"
There will be a index on < Picture-Number > in the database, to build the array for xbrowse.

Hi Uwe

Looks promising,

With a double-click on a cell, I open a file-list from a directory with all students-pictures to select a picture.

Possibly a drag and drop!

There will be a index on < Picture-Number > in the database, to build the array for xbrowse.

Do you intend to rename the <Picture-Number>?
What about date the picture was taken - cameras automatically allocate a number to the next picture taken.
Maybe the picture directory name will contain the year.
An option is to index on the data file - Student Class - and have a field in this student data
file containing the <Picture-Number> to fill the array.

Useful stuff.

Jonathan
