Multiple files if either (1) the output image's file format does not allow multi-image files, In summary, ImageMagick tries to write all images to one file, but will use Will create a sequence of 17 images named my00morph.jpg, my01morph.jpg, my02morph.jpg. $magick> convert logo: rose: -morph 15 my%02dmorph.jpg These strings, such as ' %d' or ' %03d', are familiar to those who have used the standard printf()' C-library function. Including a C-style integer format string in the output filename will automagically enable +adjoin and are used to specify where the -scene number is placed in the filenames. Per file (for example, GIF, MIFF, and TIFF). To separate files, whether or not the file format allows multiple images Use +adjoin to force each image to be written Suffix, in order to make distinct names for each image. Modified by adding a -scene number before the Such, if more than one image needs to be written, the filename given is Image per file, and in that case ImageMagick is forced to write each image as a separate file. However, some formats, such as JPEG and PNG, do not support more than one

I'm allready have a UDF to adjust the brightness but now how to detect when needed.įunc _AlterBrightness ( $StartCol, $adjust, $Select = 7 ) Local $Red = String ( $adjust * ( BitAND ( 1, $Select ) 0 ) + BitAND ( $StartCol, 0xFF0000 ) / 0x10000 ) Local $grn = String ( $adjust * ( BitAND ( 2, $Select ) 0 ) + BitAND ( $StartCol, 0x00FF00 ) / 0x100 ) Local $blu = String ( $adjust * ( BitAND ( 4, $Select ) 0 ) + BitAND ( $StartCol, 0x0000FF ) ) Return Hex ( _AlterBrightness _Limit _Column ( $Red ), 2 ) & Hex ( _AlterBrightness _Limit _Column ( $grn ), 2 ) & Hex ( _AlterBrightness _Limit _Column ( $blu ), 2 ) EndFunc =>_AlterBrightness Func _AlterBrightness _Limit _Column ( $cc ) If $cc > 255 Then Return 255 If $cc _AlterBrightness_Limit_ColumnĮxpand collapse popup #include #include #include see Local $c1 = 0xFFFF00 Local $c2 = 0x0000FF GUICreate ( "Calculate color Contrast", 550, 400 ) GUICtrlCreateLabel ( "", 50, 50, 200, 200 ) GUICtrlSetBkColor ( - 1, $c1 ) GUICtrlCreateLabel ( "", 300, 50, 200, 200 ) GUICtrlSetBkColor ( - 1, $c2 ) Local $iContrast = ColorContrast ( $c1, $c2 ) GUICtrlCreateLabel ( Round ( $iContrast, 3 ), 225, 300, 100, 30, $SS_CENTERIMAGE + $SS_CENTER ) GUICtrlSetFont ( - 1, 24 ) GUISetState ( ) While True Switch GUIGetMsg ( ) Case $GUI_EVENT_CLOSE ExitLoop EndSwitch WEnd Func ColorContrast ( $iC1, $iC2 ) Local $iL1 = RelativeLuminescence ( $iC1 ) Local $iL2 = RelativeLuminescence ( $iC2 ) Return $iL1 > $iL2 ?

I'm right this wil give the contrasted color but that is not what I'm looking for.
