Fabien,
thank you for your tips. I cannot remove
fr.cached = True
before the file open dialog comes up:
Dialog.Title = "Save image file..."
...
If I do remove the line, the file dialog comes to halt, taking minutes to
display a single file entry. Maybe may Gambas application is refreshing i
Thanks for the link to sourceforge.

works fine? I suspect that on the first run, you see some sort of blue-ish
stripes, and what happens after "Load" and selecting a PPM image? On my
system, nothing happens if I use "Paint.DrawImage". Only if use the
Paint.brush method, it works, and the loaded image is displayed.

work fine here

Hi Tobi,
this is very kind of you. Your sample project works like a charm: I see the
pixels update and change color randomly.
The problem with my project is: After I fill my image with color data, it
gets displayed correctly. Then I fill in new color data, and it is not being
updated anymore. Whi

The stream ByteOrder property defines the byte order (little endian or
big endian) used by the READ and WRITE instructions when us
Monsieur,
here is a demo project I uploaded:

Basically, click on "Load", and you are prompted for a binary PPM or PGM
file. The picture is then displayed. If you click on "Save", you can select
a new filename and save the picture

No, I am not calling "Refresh" in the mousemove event, only once after the
image data has been read in.
I set "cached" to "False". Still, the image does not appear with
"DrawImage". But with painted brushes, it works. I can live with that. I
just wished I understood the logic behind why some of th
are you calling the refresh in the mousemove event ?

My program ran fine until I inserted the line
"img.Clear"
"img" is of type Image and properly instantiated.
In the project, I already used "img" to store integers as color values for
the pixels.
The line crashed the first time Gambas tried to execute it. I can reproduce
it as often as I like. I h
Hi Tobias,
thanks for looking into this:
In the fr.Draw() event handler, when I plot my image pixel by pixel, using
this code:
For y = 0 To img.Height - 1
For x = 0 To img.Width - 1
Draw.Foreground = img[x, y]
Draw.Point(x, y)
Next
Next
the image appears. But this

Hi Fabien,
thank you for your prompt reply. I must be missing something, I guess. It
still does not display the image.
In the Form_open event, I set
fr.cached = false
I see the effect when I drag the window with the mouse. It is slow and a bit
jerky as, I guess, the redrawing is taking place

Dear list members,
in my program I seemingly cannot get an image to be painted.
I have a DrawingArea called "fr".
In memory I keep an image named "img".
In my form code, I declare
public img as image
In the Form_Open handler, I instantiate "img" with
img = New Image(fr.Width, fr.Height
