c# - Image from manually created byte[] -


i want create image byte[] create manually, jit error

system.argumentexception: parameter not valid. @ system.drawing.image.fromstream(stream stream, boolean useembeddedcolormanagement, boolean validateimagedata)    @ createbitmapfromstream.form1.form1_load(object sender, eventargs e) in c:\data\c#-workspace\createbitmapfromstream\createbitmapfromstream\form1.cs:line 35    @ system.windows.forms.form.onload(eventargs e) ...

here code:

private void form1_load(object sender, eventargs e) {   var data = new byte[20*10];   (int = 0; < data.length; i++)   {     if (i < 100)       data[i] = 0x15;     else       data[i] = 0x99;   }    using (var ms = new memorystream(data))   {     var img = image.fromstream(ms, true, true);       panel1.backgroundimage = img;   } }

what doing wrong?

an image constructed according format.

it's not sequence of pixels. if want draw pixels, use bitmap class provided system.drawing

bitmap b = new bitmap(1, 1); b.setpixel(0, 0, color.gray);

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
