HelloWorld,

I have the feeling there is a way to compress image files with a vba script. If anyone agrees to that can we take up that challenge?


Basically, I will be compressing from a folder. And will like the smallest size possible.

Say below 100kb .

Thanks in advance
Kelly
 

Excel Facts

Why are there 1,048,576 rows in Excel?
The Excel team increased the size of the grid in 2007. There are 2^20 rows and 2^14 columns for a total of 17 billion cells.
So I have been able to search and come across these codes.

I don't reallyunderstand them. But I have the feeling they can be tweaked to my needs. Can someone with that skills fix it for me? By compress I mean reduce in bytes not dimensions.

Thanks

Code:
Sub CompressPic()
Code:
[COLOR=#333333][FONT='inherit']    If TypeName(Selection) = "Picture" Then[/FONT][/COLOR]
[COLOR=#333333][FONT='inherit']        Application.SendKeys "%a~"[/FONT][/COLOR]
[COLOR=#333333][FONT='inherit']        Application.CommandBars.ExecuteMso "PicturesCompress"[/FONT][/COLOR]
[COLOR=#333333][FONT='inherit']    End If[/FONT][/COLOR]

[COLOR=#333333][FONT='inherit']End Sub

This is the code that loads the images. So when I print the worksheet, (I print through a loop which can take up say 100 counters ) the file size grows . I have no idea why. That's why I need to compress image before run the loop. Thanks

Code:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim fPath As String, sFile$
If Target = Me.[h9] Then
    fPath = ThisWorkbook.Path & "" & Me.CmbTerm.Text
    sFile = Dir(fPath & "" & Right(Me.[h9].Text, 3) & ".*")
    If sFile <> vbNullString Then
      Me.Image1.Picture = LoadPicture(fPath & "" & sFile)
    Else
        Me.Image1.Picture = LoadPicture("")
    End If
    If Err.Number = 53 Then Me.Image1.Picture = LoadPicture("")
End If
End Sub

I sorted image file size compression last summer, took me 8 months to write. I have to get files under 4MB for uploading to a client database all day.

I've added some code before the macro, so a MsgBox appears briefly at the end, I use this MsgBox active window text in a Log Macro in Excel, which records all active windows text.

I have a copy of this macro as macro c lowercase with the SendKeys as E for 96ppi.

Currently I'm trying to simplify the macro by detecting Compression options: "Apply only to this picture" and always ensure it is unticked. I couldn't work this out, so my loop of all images will either apply to that image selected, or all images. I want to save time and not loop through all of them. Stumped me still.
