1.22.7 BLOX.BImage: image management

blank

Blank the corresponding image

data: aString

Set the image to be drawn to aString, which can be a GIF in Base-64 representation or an X pixelmap.

dither

Recalculate the dithered image in the window where the image is displayed. The dithering algorithm used in displaying images propagates quantization errors from one pixel to its neighbors. If the image data is supplied in pieces, the dithered image may not be exactly correct. Normally the difference is not noticeable, but if it is a problem, this command can be used to fix it.

fillFrom: origin extent: extent color: color

Fill a rectangle with the given origin and extent, using the given color.

fillFrom: origin to: corner color: color

Fill a rectangle between the given corners, using the given color.

fillRectangle: rectangle color: color

Fill a rectangle having the given bounding box, using the given color.

image: aFileStream

Read a GIF or XPM image from aFileStream. The whole contents of the file are read, not only from the file position.

imageHeight

Specifies the height of the image, in pixels. This option is useful primarily in situations where you wish to build up the contents of the image piece by piece. A value of zero (the default) allows the image to expand or shrink vertically to fit the data stored in it.

imageWidth

Specifies the width of the image, in pixels. This option is useful primarily in situations where you wish to build up the contents of the image piece by piece. A value of zero (the default) allows the image to expand or shrink horizontally to fit the data stored in it.

lineFrom: origin extent: extent color: color

Draw a line with the given origin and extent, using the given color.

lineFrom: origin to: corner color: color

This method’s functionality has not been implemented yet.

lineFrom: origin toX: endX color: color

Draw an horizontal line between the given corners, using the given color.

lineFrom: origin toY: endY color: color

Draw a vertical line between the given corners, using the given color.

lineInside: rectangle color: color

Draw a line having the given bounding box, using the given color.
