I don't think I've posted this before. It's a small image I use, showing the various paths for getting an image into a PowerBASIC application/control. Right now, I've got it shown as my desktop image, just for easy access while I'm doing some graphics programming.
On the left are the image sources that PowerBASIC application can use - *.bmp files and *.pbr resource files.
The terminology "x3" refers to any of the three allowed graphic targets: Graphic Window, Graphic Control, Memory Bitmap.
On the right, in green, is a short statement of whether the entire image is affected by the function, or whether it can operate on part of the image. Also in green is whether the statement can resize the image.
For example, the last line says that a *.bmp disk file can be pulled into a Memory Bitmap using the Graphic Bitmap Load statement. The entire image is loaded and cannot be resized during loading.
The 3rd line says that any graphic target ("x3") can use Graphic Copy to copy part/all of an image to another graphic target, but cannot resize it during the step.
Finally, the 5th line says that a *.pbr can be used to create an ImageList, which the Graphic Imagelist statement can use to copy a complete image to any of the graphic targets ("x3") without resizing.
This helper image does not address Image, ImageX, ImgButton or ImgButtonX controls - all of which require an image from a *.pbr resource file. Nor does it describe how to add an image to a *.pbr file.
I hope this is useful to some of you. If anyone finds something wrong with it, or has a suggestion on a better format, please let me know.
