Hello

I open a picture on my computer, and want to access the graphics. The picture is not nil, but the graphics are Nil. How is this possible?

[code] Dim picFile As FolderItem  
picFile = GetOpenFolderItem()

If picFile \<\> Nil Then  
Dim pic As Picture  
pic = Picture.Open(picFile)

```
pic = ModernizePicture(pic)

pic.Graphics.ForeColor = &cFFFFFF
pic.Graphics.TextUnit = FontUnits.Pixel
pic.Graphics.TextSize = 50[/code]
```

Just tested, picFile.IsWriteable returns true.

What does “ModernizePicture” do? Can you post the Code please?

Hello

It was the ModernizePicture function from this page: [http://documentation.xojo.com/index.php/Picture](http://documentation.xojo.com/index.php/Picture)

But I found out what was wrong. It had something to do with HiDPI support.

ModernizePicture was:

[code] If input.hasAlphaChannel Then Return input

Dim result As New Picture( input.Width, input.Height )  
result.HorizontalResolution = input.HorizontalResolution  
result.VerticalResolution = input.VerticalResolution  
result.Graphics.DrawPicture( input, 0, 0 )  
Return result[/code]

I deleted the first line, now it ALWAYS makes a new copy of the image. Now it works. I totally don’t understand why an image would be immutable because of HiDPI, but apparently, it is.

Thanks for thinking with me!
