hi,
let suppose
bmp = new Bitmap(530, 335);
I think it’s means that bmp is consist of 530 x 335 pixels.
Am I right ?
|
|
|
|
|
Yes 530 is pixels width and 335 is height.
|
|
|
|
|
You are correct.
Take care,
Tom

Or even looked at the constructor tooltip when typing. It's the 5th overload of the constructor out of 12. Says very clearly Bitmap.Bitmap(int width, int height)
|
|
|
|
|
Or even checked the .Width or .Height of the bitmap after construction.

I am working with large files in a compressed state. From what I can find it is not possible to copy compressed files without uncompressing first. Does anyone know if it is possible to copy compressed files compressed? As I am writing the code in C# I have included the question here.
Thanks for any help.

What do you mean by "copy"?

The archive contains 3-7 files, if a change is made to one file the old archive is maintained "as is" and a new one with the change is created. The files which were not changed need to be added to the new archive, or copied.

to modify the contents of a compressed archive it will need decompressed and recompressed afterwards. I suspect you can find a library that will hide the details for you.

What library are you using to create your archives?
Technically, it's possible to copy a file from one archive (e.g. a .zip file) to another archive without decompressing it first. But this really depends on the archive's format. For example, I think you can do it with .zip files, but other formats I'm not sure. In reality, I'm not sure if archive libraries have this type of feature.
Take care,
Tom

I have been working mostly with #ZipLib which does use the .zip files. Any thoughts on where I can look for how to do the copy compressed?

I haven't tested this, but it looks liks you can get the ZipEntry from the first archive and add it to the second archive. You may need to Clone the ZipEntry.
Let me know if this doesn't work.
Take care,
Tom

I would guess that the methods for copying just any file would work fine.

What I have been able to find and play around with, as soon as the compressed file is put on a stream for copying it is uncompressed. To put it into another archive requires re compression. As the file sizes are gig this is a heavy time/cpu crunch. If the copying could be done compressed the time/cpu would be saved.

double zip the files?
ie zip each file separately at your chosen level of compression, and then use a 0% compression outer zip as a container. Inserting/extracting from the outer zip should be no more expensive than any other file copy operation.

you can copy an compressed bytestream just as easily as an uncompressed one. The copy will also be compressed. If you want an normal copy you'll need to decompress it first.

Lithium actually.
Does anyone know how to enable auto-scroll in the Lithium control of the Netron project?
Thanks.

Select the lithium control and set the AutoScrol property to True. Sorry if the answer sounds fascetious, but that's what I did when I used it.

Thanks, but I actually went through all the properties and saw that one. Didn't do squat. I also tried setting it programmatically using, but to no avail.
lithiumControl.AutoScroll = true;
lithiumControl.HorizontalScroll.Enabled = true;
lithiumControl.VerticalScroll.Enabled = true;
lithiumControl.HorizontalScroll.Visible = true;
lithiumControl.VerticalScroll.Visible = true;
The version I'm using is v3.3.2831.18624 from SourceForge[^].
Any other suggestions? The example it came with also does not scroll.

Do you still have your last working example or do you have any graph suggestions?

I am trying to calculate time differences in C#, I get the start time in a Lable1 and end time in Lable2, and The start time can start at 23:30 and end time at 0:30hrs, I am only looking for difference in time. Please advice.

You may subtract one time from other if you store data in two variables of DateTime type.
Such as-
DateTime i,j;
j.Subtract(i);
I hope this helps .
