Missing images in xBrowse
Posted: Thu Nov 07, 2019 03:07 PM

Hello,

I want to list all created bmp's from a defined directory
I noticed all normal Bmp's are visible but not the created ones.
The images are OK because they are visible at the bottom on
xBrowse row-selection

saved like

oBmp1:SaveToBmp( c_path2 + "Img64_" + ALLTRIM(STR(nCount[1])) + ".bmp" )

in xBrowse

WITH OBJECT:aCols[ 1 ]
:cDataType := 'F'
:nDataBmpAlign := AL_CENTER
:lBmpTransparent := .f.
//:lBmpTransparent := .t.
END

some of the created Bmp's

any idea

regards

Maybe if you increase the row height of the xbrowse?

The row-height is defined with 65 pixel
to show a image with the max size of 64x64.
It is funny that only the saved images are not visible.
I can copy any other image to the directory
like shown in the screenshot from above and it works.

I think I will create a working test to show the effect

We do not know your xbrowse code.
We also do not know if the bitmaps created are valid bitmaps.
We can advise if you provide a self contained sample program.

I think I found what happens

We also do not know if the bitmaps created are valid bitmaps.

1. I did a screenshot

ACTIVATE WINDOW oWnd ;
ON RIGHT CLICK oWnd:SaveToBmp( "test.bmp" )

2. using < PIXELFORMER > the problem is visible.
The filemanager is showing the normal bmp.

Loading the file I'm getting a funny result, everything is transparent.

We do not know your xbrowse code.

That is the reason xBrowse doesn't show the created bmp

The same happens using another freeware < xNView >
Again a different result.
Now the filemanager and editor are showing < Test.bmp > as a transparent image

maybe another solution instead of using :SaveToBmp ?
I tested :
hBmp := FW_MakeYourBitmap( 64, 64, { |hDC,w,h| GradientFill( hDC, 0, 0, h, w, ;
{{ 1, aColors[2] , aColors[4] }} ) } )
FW_SaveImage( hBmp, AllTrim( c_path2 + "Img64_" + ALLTRIM(STR(nCount[1])) + ".bmp" ) )
but the same result created but not visible in xBrowse

3. using a professional program < COREL Paintshop Pro >.
The filemanager and editor are showing the normal bmp.

There must be something wrong with the file-format

the created oWnd:SaveToBmp( "test.bmp" )

another test
loaded and saved again with a new name without any changes
now it works

I changed to xImage and added a export-format-option.
A created JPG is ok, a BMP is not visible

is there any solution for BMP's

You may get this problem in case of bitmaps with only 2 colors.

Please try
oCol:lBmpTransparent := .F.

I tested with a screenshot ( many colors ) and got the same result
it seems to be somethig wrong with the BMP-format

The BMP is created but not visible in xbrowse

I found a working solution for the moment

If BMP-format is selected I create a working PNG
next I load the PNG and save as BMP
next I delete the PNG

Code (fw): Select all Collapse

IF cType = ".bmp"
     cCounter := ALLTRIM(STR(nCount[1])) 
     cFile := c_path2 + "Img64_" + cCounter + ".png"
     oBmp[5]:Save( .T., cFile )
     FW_SaveImage( FW_ReadImage( nil, cFile )[ 1 ], ;
           c_path2 + "Img64_" + cCounter + cType )
     DELETE FILE &cFile
ELSE
     oBmp[5]:Save( .T., c_path2 + "Img64_" + cCounter + cType, 100 )
ENDIF

I still can not believe that xbrowse can not display a valid bmp and you have to find workarounds.

Can I see the bitmap that xbrowse can not display? If that is the case we will find a solution.

with the new release I'm working on
I can change the XImage background-brush

I changed the brush and saved the image < as viewed >
I got a new image with a < blustone.bmp > - background
the brush AND image is saved correct like the filemanager shows
xBrowse shows only the image and ignores the background
maybe the tests can help to detect if there is something wrong
it seems the background is detected as transparent but it is a pattern brush

Loading the image in PIXELFORMER shows the background from
< blustone.bmp > transparent as well like xBrowse with a missing background

I think the problem doesn't belong to xBrowse

the test bbb.bmp
It looks like there is a border around that makes it transparent

I added -> oImage:lBmpTransparent := .F.
but no difference

Funny and hard to understand as a test I reloaded this posted image and it works
