Picture Quality in the General Field

[vnbabu]

Hello Everyone

I store a BMP picture in my table in a general field

When I Insert Picture in the general field, The quality of Picture is changed and it is poor, Hence if I retrive the picture from the field to print in a report or preview, I get a poor quality picture.

Any sugesstion to sort out the above problem.

Thanks in advance for all of you.


Regards

Babu

Firstly most developers would not store an image in a general field.

Do a keyword search on general and you will find many threads on that topic.

Instead store the path\filename.ext in a field in a table.

As far as quality is concerned, raster graphic, ie bitmaps, can be reduced in size without loss of quality. They can only be enlarged by a relatively small percentage.

Displaying or printing an enlarged raster graphic will always show a reduction in quality - how much is dependant on quality and nature of the original image and the percentage of enlargement.

I personally like to save my images into a Binary Memo field...

To save the bitmap:
Append Memo MyTable.MyMemo From "C:\MyPicture.bmp" Overwrite

To retrieve the bitmap:

Copy Memo MyTable.MyMemo to "C:\MyPicture.bmp"

There is no degradation of the image quality when done like this, you are simply restoring the picture you have previously saved. I used the C drive in this example code, but usually I will use the temp directory SYS(2023) as the directory where I extract the image files to when I need to use them on a form or in a report at runtime.
