There is no ability for you to change this behavior through modifications to the form file itself. Bitmap Fields Bitmap fields are available in two types – they may either be a static image loaded from a file on disk, or they may be dynamically constructed by your code using the axlGRPDrw family of functions. Both have additional considerations as outlined in the following section. Static Images When loading a bitmap file into a form file, the bitmap will normally be stretched to fit the field size indicated in the form file with the FSIZE line. In these cases, an image file sized as close to the actual size that the FSIZE line represents will look the best. If this cannot be done, using a more detailed (higher resolution) image will display better rendered in the form. When the stretch option is not being used, the bitmap will be displayed at its true resolution. This can result in your form being larger in size than you intend, but it does prevent loss of graphical precision, if you know the image looks the way you want it to.
